1. Introduction
In order to provide a proper and consisten way to handle the transmission planning for the access
network, certain rules and guidelines have been established. These rules and guidelines are
discussed in this document, occasionally including an explanation on why the rule or guideline
has been devised.
1.1 Scope
The scope of this document entails the rules and guidelines for the access transmission network
of Vodafone NL.
The information in this document is intertwined with the future plans for the network and plans
for that in the Network Evolution Plan
1.2 General strategy
The general strategy is to build and maintain an access transmission network that is future proof,
and economically and technically viable.
These three requirements are equally valid for each situation. In the sections below each of them
is explained in slightly more detail on what they entail and what is to be taken into account during
the day to day planning practices.
1.2.1 Future proof design
Any planning is to be done taking the future of the network into account. This means that
generally any alteration to the planning should not be required for the near future. Only a limited
amount of alterations should occur for the mid term future, and only in the long term future
alterations may be required for every part of the network.
This future proof concept is applicable to several parts of the planning, like topology, medium,
capacity and others.
1.2.2 Economical and technical viable
Future proof, as mentioned in the previous section, means that the chosen solution is both
economical and technical viable. It is a mixture of the ways to look at it. One should attempt to
reduce both the OPEX and CAPEX as much as possible, whilst ensuring that the technical
capabilities will suit the network for a longer period.
The difficulty is in finding the balance between (timely) investments in equipment, operational
costs and the required capabilities of the network.
1.2.3 Quality
An additional important part of the strategy is the quality of the network. The availability and the
quality of service provided by the network are to be ensured at all times.
1.3 General goal
The general goal is to design a future proof and high quality network, which encompasses the
following separate items:
Sufficient capacity, not overdoing it, yet ready for the future
Planning R&G for Access transmission
Classification C3 Page 6 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
High quality
Resilient
These goals are the starting point for the various rules and guidelines in the chapters below.
1.4 Exception handling
When this document does not provide a clear answer on an issue or when the particular situation
is not properly handled by the rules and guidelines stated in this document, specific guidance
may be requested at the Engineering department at Vodafone NL. Or simply put, the author or
someone of the replacing him or her during absence.
When a particular request on handling backhaul cannot be handled within the parameters of the
rules and guidelines stated in this document similar guidance is to be requested.

2. Total network overview
The whole transmission network used to consist of two parts: the core transport network and the
access transmission network. By means of the ‘PTN-network’, an intermediate layer is added
between them.
The network looks generally like in Figure 1.
Figure 1: A very high level layered view of the transmission network.
2.1 Core transport network
The core transport network is a meshed network connecting the MTX locations using DWDM and
dark fiber connections. Every connection is protected and all transport between any element is
routed by this network. This is also globally shown in Figure 1.
2.2 Access transport network
An overview of the access transport network, including the PTN network is shown in Figure 2.
From top to bottom one sees the PTN3900/PTN6900 equipment at the switch and MTX locations
which form the basix of the PTN network.
Towards managed fiber disclosed locations, e.g. KPN fiber sites, a connection is made to an
PTN910 or PTN950 on the RAN site, extending the PTN network to these locations. This is done
to ensure proper handling of the QoS settings of the network and provide the right priority and
delay to the various services, since this is not handled by the managed fiber connections.
Furthermore, one sees in Figure 2 the additional fiber locations like the FT’s and EF FttS sites. The
FT’s are collection points for multiple trees of microwave links.
The EF FttS locations are connected via rings between MTX locations and/or FT’s for redundancy
and function as small FT’s. In this way fiber is brought closer to the RAN locations in order to
enable (future) capacity demands.

Figure 2: A global overview of the whole access network, including the PTN network which
provides the connection to the core transmission network.
There is a slight difference on handling the different protocols, E1’s are generally still carried
towards the FT before they are delivered to the SDH network, while IP traffic is handed as quick as
possible to any PTN equipment (fiber) found on route towards the MTX location.

3. Planning framework
This chapter describes the capabilities and possibilities for the different media, protocols,
locations and such. To know what can be done and used, is vital to the actual practice of
planning.
3.1 Media
Currently there are three main possibilities as a medium: copper leased lines, fibre connections
and microwave connections. There are other options, but they are currently deployed only when
other options are not possible, e.g. attachment to local internet connection on customer
premises and similar solutions.
3.1.1 Copper leased lines
The copper leased lines are all delivered by KPN, and connections of single E1’s on sites. The E1’s
are bundled by KPN into STM-1’s and delivered at one of the switch locations.
In order to accommodate the increasing capacity demands, the amount of leased lines per
location may become quite large. Added to that KPN will cease to deliver the service in the near
future, hence a leased line solution is definitely not a preferred option due to the relatively high
OPEX and the limited duration for which it is possible.
A proactive project will probably start to exchange all copper TDM based leased lines for another
solution.
3.1.2 Fiber connections
For fibre connections there are the older Fibre Towers and the newer FttS locations or FN’s. The
FT’s have DWDM equipment available to handle very large capacity demands. The FN’s are
equipped to (currently) handle a capacity ranging from 50 Mb/s up to 1 Gb/s.
The fiber for the FT’s and about half of the FN’s is dark fiber, while the other halve is managed
fiber.
3.1.2.1 Dark fiber
The dark fibre locations (FT’s and half of the FN’s) are placed in rings with a certain set of existing
sites that will collect the Ethernet traffic of a limited amount of surrounding sites.
The FT’s have larger capacity PTN equipment and DWDM equipment to relay the traffic.
The FN locations have relatively small PTN equipment to handle the traffic and maintain the ring
structure.
3.1.2.2 Managed fiber
The managed fibre locations will consist of a modem by the vendor with a limited but premium
(none-overbooked) capacity on a radio site and a connection on the switch location. Since only IP
traffic can be handled a small PTN910 is generally placed on site to enable at least QoS and
possibly CES.
At the MTX location the connection is done via one or more GE interfaces bundling the traffic of
multiple radio loctions. The routing for each separate location is handled by unique VLAN’s. The
actual available capacity at the radio location varies with the demand.
Planning R&G for Access transmission
Classification C3 Page 10 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
There are currently two potential vendors of managed fiber:
ECS (internal solution, used when ECS is already present on the location for other
services)
KPN (commercial managed fiber vendor)
3.1.3 Radio backhaul
By far the largest amount of radio sites are backhauled via a microwave connection. Other options
are currently under investigation.
3.1.3.1 Microwave connections
Currently equipment of four different vendors is deployed in the network:
DMC-Stratex (SPII)
Siemens (SRA-L and SRAL-XD)
Ericsson (MINI-LINK Traffic Node or ML TN)
SIAE (AL, AS and ASN series)
The equipment has different capabilities, mainly due to the age and the technology at the
moment of procurement. In the following sections some of the particularities of the equipment is
described. Much more detailed information can be found in the manuals by the vendors.
For all equipment in this section, there is a clear license requirement which provides protection
from interference from others.
3.1.3.1.1 SPII
The SPII equipment is old and not capable of handling IP. Therefore, it has been decided that the
SPII hardware is to be replaced by new equipment when a change is to be made on the
connection. At the moment of writing less than 5 links exist in the network, they will be removed
within a year.
3.1.3.1.2 SRA-L /SRAL-XD
The SRA-L and SRA-XD are comparable to the SPII equipment, the incompatibility with IP make
that the approach is similar: replacement when a change has to be made to the connection. At
the moment of writing less than 80 links exist in the network, they will probably be completely
removed within 1-2 years.
3.1.3.1.3 MINI-LINK TN
No investments are done to upgrade/change the MINI-LINK TN equipment. But since much more
than the DMC-Stratex and Siemens exist (about 500 of them) and they are IP capable, the
decrease will not be as fast as for the other two vendors.
3.1.3.1.4 AL / AS / ASN
The latest equipment from SIAE is the preferred hardware for microwave connections.
Specifically the large range in modulation and options for adaptive modulation make this vendor
the currently preferred option by Vodafone.
3.1.3.2 Semi-licensed microwave connections
A new frequency band is slowly coming available, the 60 GHz band. Since this particular band is
very limited in propagation capabilities, the Regulator has decided op the option of ‘light-
licensing’. This means that the Regulator will not verify interference, it will only register the
Planning R&G for Access transmission
Classification C3 Page 11 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
connection. But since all connections can be found on one location, believed is that the various
users will take heed of the frequency space already in use for each connection.
The particular band is limited in propagation, which means that the maximum possible distance is
less than 1 km. Furthermore, the first option available are not quite adaptable on modulation,
bandwidth and output power, thus apart from some pilots, a large roll out is not expected yet.
3.1.3.3 NLOS connections
The use of None-LOS radio connections, using a frequency below 6 GHz is an option to backhaul
the traffic of smaller sites. However, one is to bear in mind that all these frequencies are none-
licensed, thus highly limited in output power. Hence, the possibilities to overcome distances,
interference from others and such are quite limited.
No further steps than pilots have been taken to investigate the possibilities.
3.2 Protocols
Several different protocols are currently in use in the network. This particular section describes
the current and the future way they are handled. One is to bear in mind that the protocol is
basically independent of the medium, but not nessecarily of the service or chosen solution.
3.2.1 Protocol options
There are multiple protocols possible, but basically they are split into two variations:
TDM
IP
ATM is actually transported via TDM, so for the transmission network it is not an additional
protocol.
TDM is found to be either PDH or SDH and used where it is still required. The IP traffic is mainly
devided into physical port types (electrical or optical) and capacity (FE, GE or 10GE) interfaces.
3.2.2 Customer demands
The access transmission network handles different ‘customers’, each with different requirements
for the connection.
3.2.2.1 GSM protocols
Currently all GSM traffic is handled via TDM. This means that on site locations E1 interfaces are
used and at the MTX location the traffic is aggregated onto STM-1 connections. The E1’s may be
handled via CES in the network and delivered at the MTX location in STM-1’s but this does not
affect the operation of the GSM site itself. In the near future it may be the case that the A-bis
interface will become IP based, but for not this is not the case yet.
3.2.2.2 UMTS protocols
The UMTS sites relay the traffic in three possible ways:
All TDM
Dual stack (TDM for synchronization and voice, while HSPA is done via IP)
Single stack (all via IP)
The actual used solution depends on the location and requirements of the site. The general
solution will become an all-IP backhaul for 3G.
Planning R&G for Access transmission
Classification C3 Page 12 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
3.2.2.3 LTE protocols
The backhaul for LTE is done via IP, no other solution is supported.
3.2.2.4 ECS services
ECS supplies IP connectivity to customer premesses and where a direct solution like fiber is not
possible the extensive RAN backhaul network (access transmission network) is used to relay the
traffic via microwave connections. This is the reverse of the managed fiber provided by ECS to the
mobile network, here the mobile transmission network provides connectivity for ECS.
Generally the demand for these services may consist of two parts:
Premium (a guaranteed bandwidth)
Best effort (the bandwidth is available, but shared with others)
3.3 Location definitions
The RAN network depends on several thousands of locations, which are defined for transmission
purposes by the amount of traffic that they relay. Each of these is briefly described in the sections
below.
3.3.1 Fiber Towers
Fiber Towers (FN’s) are a limited amount (about 60) of high structures that have the following
properties:
Part of the dark fiber meshed network
Steelwork and permissions for at least 15-20 microwave links
Virtually permanent access to the premises
They function as large collection point for many microwave links.
3.3.2 Fiber Nodes
Fiber Nodes (FN’s) are present in two variations: stand alone or hub.
3.3.2.1 Stand alone FN’s
Stand alone FN’s are locations that have a fiber connection but do not relay traffic of other
locations, this may have various causes of which two are most common:
No other option possible but a managed service for relaying the traffic (no LOS, no
permissions) and higher than copper leased line capacity demand.
Incidentally close to existing fiber making it a very good and economical solution.
Most often the first case makes it an KPN FN, the second one an EF FN.
3.3.2.2 Hub FN’s
Hub FN’s are locations that have a fiber connection and relay traffic for additional sites that is
collected via microwave links. Since multiple sites are relayed, access to the equipment should
preferably be 24/7.
3.3.3 Sites
A ‘regular’ site has no special additions to accommodate the transmission network. This means
that a regular amount of antennas is possible. There is usually no additional cabinet for the indoor
equipment; hence it must be placed inside the RBS (outdoor sites) or in a regular transmission
cabinet (indoor sites). Here the demand for round the clock access is not as pressing as for the
other locations, but it is always something important to consider.
Planning R&G for Access transmission
Classification C3 Page 13 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
3.3.4 VPN sites
VPN sites are all connected via a copper leased line to the core transmission network to provide
connectivity between the network and the PABX of the customer.
These locations will all be under scrutiny to alter the transmission as the change towards an all-IP
network will affect this as well.
3.3.5 ECS locations / KSD indoor locations
These locations always have a specific solution and will always be a tail site, when it is connected
via a microwave link. When it is connected via fiber; it will be via a managed service not in a dark
fiber ring.
For each of these a specific solution is devised, chosen as close as possible to the standard
solutions.
3.4 Routing and switching equipment
As the capacity of the network is constantly increasing, switching and/or x-connect equipment is
(going to be) placed more and more in the access transmission network.
3.4.1 Microwave equipment
The microwave equipment, both SIAE and Ericsson, contains a switch in the indoor units. This
switch is used to route the IP traffic.
For locations where the specific capabilities of the PTN series equipment is not required all the
Ethernet traffic routing will be done by using the build-in switches in the microwave equipment.
3.4.2 PTN equipment
The PTN series from Huawei is being deployed to accommodate the required switching for the
MTX locations, FT’s and FN’s.
The PTN3900 and PTN6900 are placed at the MTX locations, since they can handle larger
capacities and have specific functionality.
At the FT’s the PTN3900 is placed to handle many incoming traffic via multiple ports from the
large amount of microwave links.
The PTN950 is generally placed on hub FN’s and the PTN910 on stand alone FN’s to provide the
connection to the fiber network.
3.4.3 RXI
The RXI is handling and grooming all the Iub traffic on ATM by changing the delivered channeled
STM-1’s from the access transmission network into un-channeled STM-1’s connected to the RNC.
This will remain the case for as long as ATM is one of the solutions for the Iub interface. The
increase of locations where single stack IP is the means of transmission for the 3G sites will
decrease the amount of RXI’s in the near future.
3.4.4 DXX equipment
The DXX equipment is currently being proactively phased out.

4. General planning guidelines
In this chapter the general planning guidelines are described. These guidelines are mostly
devised in order to fulfil the strategic goals.
Only for temporary solutions, e.g. for an event or quick solution for a trouble ticket, these
guidelines may be used loosely. For all other occasions, thus the permanent solutions, these
guidelines help to create a sturdy and future proof solution.
This chapter has 3 parts: topology, medium and capacity. The topology and medium selection are
highly connected to each other, while the capacity selection depends on both the requirements
by capability and traffic capacity.
4.1 Topology evolution
The topology is evolving further and further from an tree-and-branch network with the FT’s as
collection points towards an more distributed tree-and-branch network with the FN’s as
additional collection points.
For locations where EF FN’s or microwave connections are not possible, a FN solution with
managed fiber will be used.
Overall, one will find the network looking as depicted in Figure 2, with more and more emphasis
on the FN instead of the FT’s.
4.2 Medium selection
The medium selection, the decision on whether fiber, or microwave is used depends on the actual
location, the duration of the connection and the capacity demand.
As a rule of thumb the preferred options are as follows, from most to least preferred:
Microwave
Dark fiber
Managed fiber
Other options
Depending on the cost, the decision will most often become to select the second option due to
the distance for the fiber.
4.3 Expected changes of medium per location type
The medium to relay the traffic depends on the location type, each of these is described in the
following sections.
4.3.1 Fiber Towers
All FT’s are part of the meshed core transport network, e.g. all traffic is relayed by handing it over
to the DWDM equipment handling the core transport network.
In the future the growth of the smaller FN’s my render some of the FT’s too large and they may be
reduced into a role of FN instead of FT. The amount of FT’s will therefor not increase but slowly
decrease.
Planning R&G for Access transmission
Classification C3 Page 15 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
4.3.2 Fiber Nodes
The FN’s are devided into two options: dark and managed fiber. The more permanent and
economical possible locations should be using dark fiber, while the secondary option is to use
managed fiber.
The total amount of FN’s will increase to accommodate for the increased capacity demand. These
increases are mostly triggered by separate projects.
4.3.3 Regular radio sites
The ‘regular’ radio sites are connected via microwave links or copper leased lines. These locations
will decrease due to the increase of FN’s, e.g. less sites will be using microwave links as more FN’s
will be deployed.
Locations using TDM leased lines will be transferred to either FN, microwave or a new solution.
4.3.4 Client Specific Coverage (indoor)
KSD’s will have the same treatment as the regular radio sites that have copper leased lines, since
the increasing capacity demand cannot be handled by the E1’s.
Thus these locations will be transferred to either FN, microwave of a new solution.
4.3.5 Small cells
The backhaul of traffic of small cells will depend highly on the chosen solutions for these small
cells. It may become, fiber or a radio backhaul solution. At the moment of writing there is no clear
decision on this.
4.3.6 VPN customers
The VPN customers are currently attached via copper leased lines, this should be altered
according to the availability of other solutions.
4.3.7 ECS customers
The ECS customers are always handled via microwave links, since only when fiber cannot be
arranged by ECS, the help of the access transmission network is required.
4.4 Trends from the medium selection
The trends shown for the medium selection are as follows:
No more copper leased lines for E1’s
Decrease of the amount of FT’s
Increase of the amount of FN’s
Overall it is a shift from TDM toward IP, going along with an increase in capacity, invoking an
increase in fiber and relatively stable amount of high capacity microwave links.
4.5 Capacity selection
The capacity selection is the initial choice on the required capacity per location. Measurements
on the actual utilization or congestion may give rise to capacity increases for specific paths or
hops.

4.5.1 Capacity capabilities
Every chosen medium has specific capacity capabilities, these are given in the brief descriptions
below.
4.5.1.1 Fiber Nodes
The capacity capability per FN depends on whether it is managed or dark fiber.

Table 1: The available capacity for the FN's according to the contract without cost increase.
4.5.1.1.2 DARK FIBER
The Eurofiber Fibre Nodes are connected in a ring and share a minimum capacity of 1 Gb/s on
that ring. As the average amount of sites handled per ring will be about 20, the average available
capacity per site is approximately 50 Mb/s.
A capacity increase of the whole ring to 10 Gb/s will be performed once capacity monitoring
shows the necessity for that measure.
4.5.1.2 Microwave connections
The latest microwave links can handle quite some capacity, currently up to 341 Mb/s.
4.5.1.3 Copper leased lines
Every copper leased line has a maximum capacity of only 1 E1, e.g. 2 Mb/s. Hence, this is not a
future proof solution to be used.
4.5.2 Capacity demand per technology
Each technology has different capacity demands, briefly depicted in the sections below.
4.5.2.1 2G
GSM and DCS are generally requiring 1 E1 per site, though some locations require more capacity,
up to 2 E1’s per location per frequency.
4.5.2.2 3G
The 3G capacity requirements are mainly depending on the speedcode scheme they are part of,
as well as the amount of carriers per site. This is easiest depicted in Table 2 for the sites that are
using TDM only and dual stack for the traffic.
When the site is using single stack, one should have the total Tx capacity available in IP capacity.

2 3 E1’s
3 4 E1’s
Table 2: The capacity demand for the 3G locations in the network for initial planning, actual
measurements and/or congestion may alter this per site.
In Table 2 one sees that the largest part on the capacity increase for the TDM part is due to the
increased signaling capacity when additional carriers are present on the location.
4.5.2.3 LTE
LTE capacity demands are very high per technology, Table 3 is the applicable planning guideline.
4.5.2.4 VPN customers
The VPN customers do not have a common connection as the other locations, hence the
capacity for these, until a replacement of the lease lines is possible, remains at 1 E1 for each
connection.
4.5.2.5 ECS customers
The ECS customers have varying capacity demands for both premium and best effort services.
This provides specific demands on the actual capacity to be reserved for them.
The last microwave link is only used by the ECS customer and the PTN network has a high
capacity available, hence for these no restrictions apply other than the requested bandwidth.
Only when a microwave link is shared with other sites one should take care on the total capacity
available for the service.
The following rules apply for shared microwave links:
If the maximum possible capacity on the hop minus the capacity theoretically used by
the site(s) (cumulative), according to the sections above, is larger than the requested
premium capacity, it can be granted.
When the rule above is not feasible, one is to confer with the responsible person at
Vodafone
For best effort services the rule above can be used much more lenient, but one is to verify the
actual utilization when the requested best effort capacity exceeds 25% of the maximum possible
capacity on the microwave link before implementing the connection.
4.5.3 Capacity demand per location
For the wireline solutions the capacity is set by either the managed fiber provider or the
connector used on either end.
Planning R&G for Access transmission
Classification C3 Page 18 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
The demand per location depends on the technologies (2G, 3G and/or LTE) on site, and whether
the location is a tail site or a relay point in the network.
In Table 3 one sees the capacity requirements depending on the technologies on the location for
tail locations.

Table 3: The minimum capacity demand for various locations in the network for initial planning,
actual measurements and/or congestion may alter this per site.
Notes, explanations: † When LTE800 and LTE1800 are co-located, the bandwidth of the microwave link is to be 56 MHz
in order to enable the larger throughput per user due to the carrier aggregation in the radio
parameters. The highest modulation is to be chosen: 256QAM. If this is not possible, the
exception handling procedure applies. ‡ When LTE is present on site, except for the case described above, the bandwidth of the
microwave link is to be 28 MHz using the highest possible modulation of 256QAM. If this is not
possible, the exception handling procedure applies (section 1.4).
When multiple hops are required, which should be minimized at all times, then an additional
capacity demand comes in to play:
The capacity demand of each location is to be multiplied by 0.5 and all are then to be
added to find the new total minimal capacity requirement.
The total required capacity as stated in Table 2 (no LTE present) and Table 3 (LTE
present), is to ensured for each site end to end.
When the total minimal capacity requirement exceed the maximum possible capacity, the
exception handling procedure applies (section 1.4)..

5. Microwave planning guidelines
For planning of microwave links, a specific set of rules and guidelines are applicable in order to
provide a future proof network.
5.1 Topology choices
The choices for the topology, or put differently, the A-end selection for microwave links is altered
quite a lot due to the introduction of many Fibre Nodes capable of handling large quantities of
traffic.
One has to take the following into account for this particular decision:
Amount of links per FT or FN
Amount of cascaded links
Contract with the landlord
Wind load
LOS possibilities
Upcoming changes in the network
Access to the A-end
In the sections below a more detailed description is given, but the largest factor is whether the
capacity demands of the site at hand can be handled by the A-end. E.g. the proximity to a Fibre
Node becomes essential, as well as the amount of locations relayed by the FN.
5.1.1 Amount of links per FT or FN
The amount of microwave links per FT or FN is not restricted, it merely depends on the possible
restrictions below.
The amount of locations backhauled by a FT is not restricted either, since the developments are
decreasing these numbers. The amount of locations by a dark fiber FN is limited, yet flexible:
An average of 25 locations backhauled per EF ring
An average of 5 locations actual part of the EF ring
Makes an average of 4 locations connected via microwave to an dark fiber FN
For the managed fiber FN’s there is no clear limitation on the amount of microwave links, but the
same amount of 5 (the one itself and 4 via microwave) locations per fiber connection is a proper
guideline. When it exceeds 8 locations it is to be verified whether another solution is not possible.
5.1.2 Amount of cascaded links
The guideline is to go for a no cascaded microwave links network, thus all connections should in
the end ideally become only one hop. For existing connections that are not being altered the
already present number may remain. If exceptions are required due to the restrictions given
below it is possible. The expectation is that the average amount of cascaded links will decrease as
more and more microwave links can use additional Fibre Nodes as a relay point.
5.1.3 Constraints
The constraints in planning and deployment of microwave links are contracts (permissions), wind
load and LOS possibilities.
5.1.3.1 Landlord contracts
The contracts with landlords tend to limit the amount of antennas on a site.
Planning R&G for Access transmission
Classification C3 Page 20 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
This limitation is to be taken into account when an A-end is to be selected. It may be wise to
retain possible antenna positions on specific locations.
5.1.3.2 Wind load
When the wind load on the antennas may become too large for the structure, one may have to
reconsider selecting the A-end. The redevelopment of a site is relatively expensive compared to
selecting a different A-end.
5.1.3.3 LOS possibilities
Only when the Line of Sight required for the to-be-deployed microwave link is sustainable for a
longer period the A-end can be selected.
5.1.3.4 Site accessability
When it is known that a site has limited access, either by contract or construction, then it
decreases the likelihood to select that particular location as an A-end up to the point that it
cannot be used at all.
For HVP’s the accessability takes too long to use them as an A-end at all.
5.2 Hardware selection
The selection of the hardware and vendor to be used depends on the situation, whether it is the
upgrade of an existing connection or a new connection.
5.2.1 Implementing a new microwave link
For all new links the latest equipment is to be deployed:
ODU’s: ASN series, an exception may be extremely short links in 38 GHz with AS series
IDU’s: ALCplus2e series.
5.2.2 Change of an existing microwave link
For existing connections the change is primarily an upgrade of the capacity of the microwave link.
Here the selection on the hardware is different.
SPII, SRA-L and SRAL-XD:
o The existing equipment is to be removed and replaced by equipment as if it is a
new connection.
MINI-LINK TN:
o The existing equipment is to be removed and replaced by equipment as if it is a
new connection.
SIAE AL series:
o When the upgrade is required for LTE the IDU and possibly the ODU is to
replaced. When the upgrade is requied for other technologies and it can be done
remotely, the existing hardware can remain in place. More simple: If a site visit is
required it is to become a future proof connection.
5.3 Planning guide
The sections in this part can be read as a guide through the process of planning a microwave link:
Frequency band selection
Ensure proper High/Low configuration
Bandwidth and modulation selection
Channel and polarization selection
Planning R&G for Access transmission
Classification C3 Page 21 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
Antenna selection
Configuration selection
Splitter or coupler selection
Use of waveguides
5.3.1 Frequency band selection
The available frequency bands for the Vodafone Netherlands network are 18, 23, 32 and 38 GHz.
In order to use the available frequency space in an efficient way, the following rule is to be
followed:
One is to use the highest frequency band that is possible
Thus the preferred selection sequence is first 38, followed by 32, 23 and 18 GHz. ‘Possible’ in the
rule means: whilst ensuring the required availability figures. There is a clear limit in lowering the
frequency band with regard to the distance, which is given by the Regulator in Table 4.
Frequency band Minimal distance <140 Mb/s Minimal distance ≥140 Mb/s
18 5 km 3 km
23 5 km 3 km
32 2.5 km 1 km
38 0 km (no minimum) 0 km (no minimum)
Table 4: The minimum distance matching the capacity of the microwave link and the frequency
band.
The idea is not to ‘waste’ frequency space on the lower bands for microwave links that would
operate nicely with in a higher frequency band.
5.3.2 Ensure proper High/Low configuration
Straightforward:
No High/Low conflict is allowed in the network.
5.3.3 Bandwidth and modulation selection
The bandwidth and modulation are to be selected according to the capacity requirements earlier
in this document. Previously the capacity demands were not as large as currently, hence a
thorough selection was needed.
5.3.4 Channel and polarization selection
The selection of a frequency channel consists in the actual channel selection and the
polarization selection. The rules are as follows:
F1 (H) – F1 (V) – F2 (H) – F2 (V) – F3 (H) - …
When the link is shorter than 1.5 km, the preferred option is to use H over V.
Thus the preferred polarization is Horizontal and the channels are to be selected according to the
schemes in Appendix B: The microwave frequency schemes.
Planning R&G for Access transmission
Classification C3 Page 22 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
5.3.5 Antenna selection
The antenna selection concerns the size and the type of antenna, both affect the actual
operation of the microwave connection quite a lot. Each of these are discussed in the sections
below.
5.3.5.1 Antenna size selection
The selection of the antenna size depends on multiple factors:
The rules of the regulator
Dish permissions by the landlord
Wind load on the site
The required availability figures
The Regulator uses the scheme as shown
Frequency range (GHz) Antenna size (m)
< 10 1.2
10 to 20 0.6
> 20 0.3
Table 5: The directives from the Regulator on the antenna size.
Preferred is the following rule:
Use the smallest antenna possible to please the landlord and reduce the wind load
following the scheme from the regulator
However, one may decide on a larger dish than stated according to the rules of the Regulator for
the following reasons:
Ensuring the availability
Avoiding interference
The use of a smaller antennas related to each frequency band than indicated in Table 5 is not
allowed by the regulator and will therefore not be used.
5.3.5.2 Selecting dual polarized links / antennas
The key rules on using cross polarized links using the same frequency:
Output powers are to be the same (thus the availability of Horizontal configurations is
leading)
Modulation cannot be higher than 32QAM (due to the limitation on the C/I demands and
the discrimination thereof by the polarization)
Thus one should be very, very carefull planning two cross-polarized microwave links, concerning
the availability and interference, e.g. modulation and power, certainly with using adaptive
modulation and ATPC.
When a dual polarized link cannot be avoided, one is pressed to avoid the use of dual polarized
antennas when possible. The use of one antenna per connection is definitely the preferred
configuration. However, in certain cases where it cannot be avoided, dual polarized antennas can
be deployed. The reasons for the utilization of dual polarized antennas can for example be a
restriction on the implementation of two antennas.
Planning R&G for Access transmission
Classification C3 Page 23 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
5.3.6 Configuration selection
The microwave link may be implemented with MSP 1+1 hardware protection. Hardware
protection (MSP 1+1) is only to be applied when the accessibility to the site(s) may cause an issue
to make repairs. It is possible to deviate from this rule in certain cases after consulting the
engineering department.
Some examples:
An HVP is straightforward, access is hard to arrange since the power generally has to be
rerouted, which takes more than one week to arrange.
Industrial chimneys, advertising masts and wind turbines often require a crane or
cherrypicker to access the equipment, taking quite some time to arrange, thus
protection is commonly used.
A location with an indoor solution and microwave backhaul with only access during
office hours has definitely no need for hardware protection, since at the moment there is
no access, there won’t be any users that would be affected by a failure
Regular masts are always accessible, no protection
Residential buildings generally have a key safe to grant access, hence no protection
needed
Implementing MSP 1+1 protection should be logical. Since safety regulation prohibits one to
access high places during the night, one could reason that even masts should get hardware
protection to meet repair times, yet this is not applicable. Thus other locations like residential
buildings and offices should be treated similarly.
In general only HVP’s, chimneys and such will have MSP 1+1 protection, not any other site type.
5.3.7 Splitter or coupler selection
When a links is to have hardware protection the preferred option is to use symmetrical
splitters/couplers in contrast to asymmetric splitters/couplers.
Asymmetric splitter/couplers are only to be used in order assure the proper operation
(availability) of the microwave link.
5.3.8 Waveguide selection
The deployment of waveguide is, due to the relatively fragile nature thereof, to be avoided at all
times. It is possible to deviate from this rule in exceptional cases after consulting the engineering
department.
5.4 Availability demands
The availability calculations are to be performed properly to ensure the quality of the network.
5.4.1 Ground rules
The ground rules are as follows:
The availability of a microwave link is to be 99.995% or better, due to rain influences.
Interference is not permitted and is to be estimated using the calculation tool by using
the relevant output powers and receive levels of the links at hand.
The location definition, e.g. the coordinates and the height of the location and antennas
are to be as precise as possible.
Planning R&G for Access transmission
Classification C3 Page 24 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
For the first two rules, the detailed implication using adaptive modulation and ATPC or RTPC per
microwave link are found in 5.5. The third rule is imperative to make a proper estimation on the
outcome of the first two rules.
5.5 Availability and interference calculations
The availability and interference calculations depend on whether a fixed modulation or adaptive
modulation is selected, as well as on the (possible) flexibility of the output power by means of
ATPC or RTPC.
5.5.1 Selection of ADM or fixed modulation
When only guaranteed services are handled by the microwave connection, e.g. TDM or equal
services that may be impared by decreasing the capacity, one is not allowed to use ADM. The
modulation is to be fixed. This, however, will not be the dominant case, in a few years these
locations will cease to exist.
When a microwave connection uses IP connections one is to use ADM at all times. This will
increase the overall availability by merely temporarily decreasing the capacity during the
attenuation by rain.
The selection of the range for the ADM depends on the capacity demands. The minimum
required capacity is described in section 4.5.3. The maximum chosen capacity when using ADM is
preferably one modulation higher than the required capacity. The lowest allowed capacity
depends on the bandwidth required for guaranteed services, like TDM traffic, synchronization and
any real time traffic like voice and video. Thus, only the purely data part is allowed to decrease in
capacity during atmospheric attenuation.
Modulation BW (MHz) Capacity (Mb/s)
4QAMs 28 36
4QAM 28 42
8PSK 28 63
16QAM 28 83
32QAM 28 104
64QAM 28 125
128QAM 28 145
256QAM 28 171
Table 6: The various modulations and the related capacity for microwave links using ALCplus2e
equipment with a bandwidth of 28 MHz.
For situations where the bandwidth is 56 MHz, not present in Table 6 , the various capacities are
different and can be found in iQ.link. The same way of handling ACM applies though. One is to
ensure the basic requirement for properly managing the minimum of capacity for vital
traffic/signalling like voice and synchronization.
The minimum value for the ADM is as follows:
When TDM (E1’s) is present: the E1’s are to be ensured
When no TDM (E1’s) is present: the lowest value is sufficient (4QAMs, e.g. 35 Mb/s)
Planning R&G for Access transmission
Classification C3 Page 25 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
Note!
If one allows 4QAM, one automatically allows 4QAMs as well, hence for ensuring the guaranteed
values it is as if the row of 4QAM does not exist in Table 6. But it does so in the real network.
5.5.2 Selection of ATPC or RTPC
In order to reduce the interference as much as possible, one is to use ATPC when possible.
However, to make sure that there is no unwanted interaction with ADM and reasonable benefits,
the values in the tool, as given in Table 7, are the minimal values for the border between RTPC
and ATPC.
Maximum modulation Engineering reference Minimum fade margin for ATPC
4QAM 4QAM 13
8PSK 4QAM 20
16QAM 8PSK 20
32QAM 16QAM 20
64QAM 32QAM 20
128QAM 64QAM 20
256QAM 128QAM 20
256QAM 256QAM 20
Table 7: The minimal Fade Margins (dB) to allow ATPC with regard to the maximum allowed
modulation and the engineering reference modulation.
If the fade margin is less than indicated in Table 7, RTPC is to be used.
One is to bear in mind that these parameters are set in the planning tool and one may want to
manually change them when a none-ADM microwave link is designed (which will be an
exception) the limiting fade margin for every modulations becomes 13 dB.
5.5.3 Availability calculation
The actual availability calculation is done for the engineering reference, e.g. the modulation that
is chosen to be the engineering reference. The following rule is applicable:
The engineering reference is to be the required capacity according to section 4.5.3.
The engineering reference is thus the highest or second to highest possible modulation in the
ADM range (depending on the outcome of section 5.5.1). The availability of the microwave link is
to be 99.995% for rain attenuation calculated for annual calculations.
5.5.4 Interference calculations
The interference calculations are to be done using the following parameters:
ATPC criteria swithed on (always on ‘TX ATPC’, never using ‘TX max’)
Adaptive modulation set at ‘Worst Case’ always
Evaluation of potential interference cases are to take the following items into account:
Correlated fading, the tool does not take that into account
Planning R&G for Access transmission
Classification C3 Page 26 of 33
Template 1v0 Comercial in Confidence – Copyright Vodafone 2011
Actual level of interfering signal compared to the noise floor of the equipment
By means of these two items one should be able to plan the actual frequencies more efficiently
than one would when merely the flag of potential interference by the tool is used.
