How can I efficiently use the RF spectrum?
1 13 2
RF spectrum is a preciousand limited resource for
Operators
Differentiation andprioritization of the traffic ismandatory to save the RFspectrum
With FlexiHybrid it is possibleto enable QoS via software
With Quality of
Service
Priority to most precious
traffic in case of
congestion

How can I optimize the traffic Upstream?
C1
C2
C3
C4
C < C1+C2+C3+C4
The embedded L2 switch in FlexiHybrid (in conjunction with statistical
multiplexing) guarantees the aggregation of the traffic toward the radio port, leadingto an optimal network design in the upstream and significant lower investment
in the transport network
There is also a solid benefit due to the saving of an external switch and its NMS
Hence there is a CAPEX and OPEX reduction for the customer

How can I provide more capacity for data over the
same RF spectrum keeping low the investment?
With Adaptive modulation
The Adaptive modulation is a new way for boosting the link capacity
keeping the proper Quality of Service for the different classes of traffic
It fits very well with the bursty nature of the data traffic
More capacity, same antennas, same spectrum
There is a CAPEX saving (no link re-engineering) and OPEX saving
(no on-site operations and further fees for the spectrum)
With FlexiHybrid it is possible to enable the Adaptive Modulation via software

How can I optimize the mapping of the Ethernet inthe radio?

Ethernet
Native Ethernet Stack
Radio
EthernetMapping Layer
Ethernet
Typical PDH/SDH Stack
FlexiHybrid is a packet radio, hence it features a native Ethernet stack
In a packet radio there is an improvement of the transmission efficiency
due to the elimination of the mapping layer (usually used in PDH and SDH
systems)
This benefit leads to saving in RF spectrum and less equipment spending

QoS is implemented using weighted priority queues. Incoming packets areassigned to a priority queue based on one or more of the following criteria
Incoming Port: port based priority allows assignment to a priority queue basedupon the port the packet arrived on
802.1Q VLAN Tag Priority: packets are assigned to a priority queue basedupon the priority tag field in the VLAG TAG
IPv4 TOS: packets are assigned to a priority queue based upon the TOS field inthe IPv4 header
DiffServ: packets are assigned to a priority queue based upon the value of theDS field of the IPv4 header (the DS field is the re-defined IPv4 TOS field)
