INTRODUCTION

Rapid growth of mobile Internet and other mobile services has resulted in increasing demand

for higher data transmission capacity. Based on WCDMA, UMTS is one of the evolving 3G

mobile communications systems designed to meet this demand. High bit rates for both circuit

and packet switched services allow mobile multimedia, i.e. voice, data, video, etc in the same

call. Since UMTS uses the same core network as GSM and GPRS, it allows operators to use

existing infrastructure during the rollout phase. Coverage planning is performed with a

planning tool including a digital map with topography and population distribution

information of the area.

PROJECT OBJECTIVES

The task of planning a network can be very challenging as it involves many careful studies

with a lot of considerations, and at times trial and error. The aim of this project is to

undertake initial pilot channel coverage plans for a 3G network within the ring road boundary

of Oxford City. The target for coverage planning is to find optimal locations for base stations

to build continuous coverage according to the planning requirements.

ASSET3G is a network planning and analysis tool containing a complete range of

functionality for the design and simulation of GSM, PCS, AMPS, TDMA, TACS,

PMR/TETRA/iDEN, UMTS, DVB-H, W-CDMA, CDMA2000, EV-DO, TD-SCDMA and

WiMAX networks. Its functionality includes hierarchical network planning, propagation

modelling, service definition, analysis arrays, neighbour list definition, automatic frequency

planning, CW data analysis, detailed reporting and simulation of network performance

LOCATION AREA AND SITE SURVEY

Oxford is a city and the county town of Oxfordshire in South East England located at

51°45′07″N, 1°15′28″W. The city has population of just fewer than 165,000, with 151,000

living within the district boundary with a total area of 17.6 sq mi (45.59km2

) and a population

density of 8,469.3/sq mi (3,270/km2).

TOTAL COVERAGE AREA ANALYSIS3

Fig. 3: Oxford city map showing the intended area to be served

From the map in fig.3 above, to provide full coverage within the ring road, the circle in the

figure has to be considered, since Oxford ring road is not a perfect sphere.

The area inside the ring road can be calculated as follows:

The longest (A) and shortest (B) distance from the center of the circle to the boundary of the

ring road are:

A=4.78km, B=2.48km, then the longest area A1 and shortest areas A2 can be calculated as

follows:

found to be approximately equal to 46km2

which is going to be considered in this project.

TASK1

ANTENNA CONCEPTS

An antenna is a device that is made to efficiently radiate and receive radiated electromagnetic

waves. Antenna transform wire propagated waves into space propagated waves by receiving

electromagnetic waves and pass them onto a receiver or they transmit electromagnetic waves

which have been produced by a transmitter.

There are several important antenna characteristics that should be considered when choosing

an antenna for an application, the characteristics are explained below.

• Power Gain

• Directivity

• Polarization

• Antenna radiation patterns

ANTENNA POWER GAIN

The power gain of an antenna is a ratio of antenna power input to the power output from the

antenna as shown in equation (1). Unless otherwise specified, the gain refers to the direction

of maximum radiation. The gain is a dimension-less factor related to power and usually

expressed in decibels.

................................................................................ (1)



- 6 -

EQUIVALENT ISOTROPICALLY RADIATED POWER (E.I.R.P)

Is the amount of power that an isotropic antenna will emit to produce the peak power density

observed in the direction of maximum antenna gain. As given by the relation below:

......................................... (2)

Where PT is the power transmitted in dBm, Lc is the cable loss in dB and G is gain expressed

dBi.

The EIRP is used to estimate the service area of the transmitter and to co-ordinate

transmitters on the same frequency so that their coverage areas do not overlap. In built-up

areas, regulations may restrict the EIRP of a transmitter to prevent exposure of personnel to

high power electromagnetic fields however, EIRP is normally restricted to minimise

interference to services on similar frequencies.

DIRECTIVITY AND RADIATION EFFICIENCY

The directive gain of an antenna is a measure of the concentration of the radiated power in a

particular direction. It may be regarded as the ability of the antenna to direct radiated power

in a given direction. It is usually a ratio of radiation intensity in a given direction to the

average radiation intensity.

Directivity relates to the power radiated by antenna (PO) and Gain relates to the power

delivered to antenna (PT).



- 7 -

where η is the radiation efficiency (0.5-0.75)

POLARIZATION

Polarization is the orientation of electromagnetic waves far from the source. The power

received by antenna from a particular direction is maximal if polarization of the incident

wave and the polarization of the antenna in the wave arrival direction have the same axial

ratio, sense of polarization and spatial orientation. So for best performance you will need to

match up the polarization of the transmitting antenna and the receiving antenna.

There are several types of polarization that apply to antennas.

Linear Polarisation this comprises, Vertical, Horizontal and Oblique

Circular Polarisation this comprises, Circular Right Hand (RHCP); Circular Left Hand

(LHCP), Elliptical Right Hand and Elliptical Left Hand.

Polarization is most important if you are trying to get the maximum performance from the

antennas.

ANTENNA RADIATION PATTERNS

The radiation pattern is a graphical depiction of the relative field strength transmitted from or

received by the antenna. Antenna radiation patterns are taken at one frequency, onepolarization, and one plane cut.

Antenna radiation patterns usually take two forms, the elevation pattern and the azimuth

pattern. The elevation pattern is a graph of the energy radiated from the antenna looking at it

from the side as shown in fig.4a. The azimuth pattern is a graph of the energy radiated from

the antenna as if you were looking at it from directly above the antenna as shown in fig 4b.



- 8 -

When you combine the two graphs, we have a 3-D representation of how energy is radiated

from the antenna as shown in Fig.4c

When chosen a radiation pattern there are some key elements to be considered the major

elements includes.

- Gain

- Beam Width

- Nulls (Positions)

- Side-lobe levels

- Front-to-back ratio

- Beam Tilt

Beamwidth

Beamwidth of an antenna pattern is a measure of its directivity, the angle between the half

power (-3dB) points of the main lobe. In other words is defined as the angle between the

directions in which the radiated power is 3dB below the maximum. It is usually expressed in

degrees as shown below.

Fig5: Radiation pattern showing beamwidth

Nulls



- 10 -

Null fill is used in radio antenna systems which are located on mountains or tall towers, to

prevent too much of the signal from overshooting the nearest part of intended coverage

area. Null fill does not come without a penalty, however, generally slightly lowers the gain of

the antenna.

Front-to-back ratio

The front-to-back ratio (F/B) is used as a figure of merit that attempts to describe the level of

radiation from the back of a directional antenna. Basically, the front-to-back ratio is the ratio

of the peak gain in the forward direction to the gain 180-degrees behind the peak. On a dB

scale, the front-to-back ratio is the difference between the peak gain in the forward direction

and the gain 180-degrees behind the peak.

Beam tilt

Beam Tilt is used in radio to aim the main lobe of the vertical plane radiation pattern of an

antenna below (or above) the horizontal plane.

The simplest way is mechanical beam tilt, where the antenna is physically mounted in such a

manner as to lower the angle of the signal on one side. However, this also raises it on the

other side, making it useful in only very limited situations. More common is electrical beam

tilt, where the phasing between antenna elements is tweaked to make the signal go down

(usually) in all directions. This is extremely useful when the antenna is at a very high point,

and the edge of the signal is likely to miss the target entirely.

Side-lobe levels

Side-lobes are the lobes of the far field radiation pattern that are not the main beam as shownin Fig.2 above. The power density in the side lobes is generally much less than that in the

main beam. It is generally desirable to minimize the side lobe level (SLL).

ANTENNA SECTORISATION



- 11 -

Sectorisation is commonly used technique to enhance capacity or coverage by equipping the

site with (more) sectors. It is traditionally provided by means of directional high gain

antennas. Each of the sectors creates a new cell.

With sectorisation, due to the newly created cells, coverage and capacity can be improved in

both directions. Depending on the application, the site may be comprised of one sector

(omnidirectional antenna) or sectored (Directional antenna).

Omnidirectional antenna, an omnidirectional antenna is an antenna that has a non-

directional pattern (circular pattern) in a given plane with a directional pattern in any

orthogonal plane.

Directional antenna A, a directional antenna is one that radiates its energy more effectively

in one (or some) direction than others. Typically, these antennas have one main lobe and

several minor lobes

To provide services in an isolated area, single sector (omnidirectional antenna) approach is

applicable to micro or pico cells, as well as macro cells; the cell requires being isolated from

the remaining network by, e.g., terrain obstacles.

Two sectors may be employed for line coverage at macro layer (e.g. sites along the

motorway) or for coverage and capacity of dense areas at micro layer. Three sectors can be

used to provide regular footprints of the network service at macro layer with low or medium

load, and six sectors to provide additional capacity and improved coverage to regular macro

layers.

The performance of a sectorised site is mainly given by the horizontal (azimuth)

characteristics of the used antennas and, obviously, the number of sectors. The more the

sectors are used, the narrower the beamwidth of the antennas has to be. A narrower antenna

provides usually a higher directional gain, and hence improves the link budget in both

directions. In addition, less overlapping between neighbouring sites is provided; thus, less

interference is received from other cells and less soft handover overhead is present.

TASK 2 & 3

By Ibrahim Mohammed Gumel

TASK 2

Path loss is the reduction in power density (attenuation) of an electromagnetic wave as it

propagates through space. Path loss is a major component in the analysis and design of

the link budget of a telecommunication system.

This term is commonly used in wireless communications and signal propagation. Path loss

may be due to many effects, such as free-space loss, refraction, diffraction, reflection,

aperture-medium coupling loss, and absorption. Path loss is also influenced by terrain

contours, environment (urban or rural, vegetation and foliage), propagation medium (dry or

moist air), the distance between the transmitter and the receiver, and the height and location

of antennas.

The aim of this task is to relate the general path loss formula for the Macrocell cell model 3

used in this coverage and the Hata model. These models determine the path losses of the

radio signal.

MACROCELL MODEL 3

The asset3G uses generic path loss model which can be adjusted using various parameters. In

our work we used Macrocell model 3 for all cells. The general path loss formula for the

Macrocell model is:

Where

d Distance from the base station to the mobile station (km)



- 19 -

Hm Height of the mobile station above ground (m)

Heff Effective base station antenna height (m)

Diffn Diffraction loss calculated using either the Epstein-Peterson, Bullington,

Deygout or Japanese Atlas knife edge techniques

k1, k2 Intercept and Slope. These factors correspond to a constant offset (in dBm) and

a multiplying factor for the log of the distance between the base station and

mobile.

k3 Mobile Antenna Height Factor, Correction factor used to take into account the

effective mobile antenna height.

k4 Multiplying factor for Hm

k5 Effective Antenna Height Gain, this is the multiplying factor for the log of the

effective antenna height.

k6 Multiplying factor for log (Heff)log(d)

k7 Multiplying factor diffraction loss calculation

C_Loss Clutter specifications such as heights and separation are also taken into account

in the calculation process.

HATA MODEL

The original established Hata path loss model is

LdB=

Where A(hr)= the correction factor for the height of the

receiving antenna and ht and hr are the transmitter and receiver height respective the A(hr) for

small or medium sized city, and is only valid 150 MHz to 1500 MHz

The original Hata model is only valid for frequencies between 150 and 1500 MHz, but has

been extended by COST 231 to 1500 to 2000 MHz.

The basic equation for predicting path loss in (dB) using COST-231 Hata model is shown in

Equation below.

The two path models are same with only small discrepancies when comparing the constant in

which Hata model shows 164.15 and Macrocell model 3 shows 164.74. Also comparing the

coefficients of Hm, Hata model shows 2.93 while Macrocell model 3 shows 2.55. Apart from

this the two models are the same.

This comparison shows great similarities between the models as also shown in the graph in

fig.11 below

Fig 11: Graph of Path loss models against distance



- 23 -

TASK 3

The aim of this task is to find values for k1-k7 parameters which would make the path loss

model for a UMTS macrocell represent a FSPL model.

The free space path model is shown in equation (3.1) below

FSPL= ..................................................................................... (3.1)

Simplifying the equation we have

=

= ................................................................................... (3.2)

Taking f=2000MHz, c= 3x108m/s

Where c, is velocity of light in the air, f and are the frequency and wavelength

of transmission respectably

, =0.15m

Substituting in equation (3.2) above

FSPL =

FSPL =

FSPL = .................................................................................................... (3.3)

To determines k1-k7 parameters values, simplified free space path loss in equation (3.3)

above is compared with general path loss formula for Macrocell model below

We have

K1= 38.47

K2=20, while k3= k4=k5=k6=k7= 0



- 24 -

This indicates that free space path model is not suitable for mobile environment because it

does not take care of many factors that cause losses in the mobile environment. This is shown

in the fig 11 above which shows the free space path model is far below the macrocell model 3

and Hata model.

SCRAMBLING CODE

In both the UL and DL, spreading codes are used to spread the signals to the required chip

rate and provide channelization. The signals spread by the channelization process is also

scrambled

-There are 64 code groups

-Each group containing 8 primary codes

-The scrambling ID can be calculated by 64*8=512, so there are 512 primary scrambling

codes

The sequence can be generated as follows:

Each Node B differ from each other in the scrambling code ID by a factor 8 while each cell

within the given Node B differ by a factor of 1

Let Node Bk

n represents a base station where

k can take a value from 0 to m (0 been the first Node B and m the last Node B)



- 26 -

n can take values 0, 8, 16, 24, 32, 40 ……,

TASK 6

NOISE RISE AND ORTHOGONALITY FACTOR

Noise rise (NR) is the ratio of the total received wideband noise to the thermal noise power.

The orthogonality factor: orthogonal codes in the down link is used to separates users and the

degrades, accounted by j

the noise rise increases. A point is reached where by as the noise rise increases the penalty is

so large where by there is no power budget available for the radio path loss and this point is

called the pole capacity and the maximum noise at this point is called the noise rise limit

From fig. 14 above it clearly show that the noise rise decrease as the Orthogonality factor

increases with an increase in distance.

TASK 7

Pilot Power is 33dBm

Maximum power is 43dBm

EIRP is 62.5dBm

Pilot power +29.5 =EIPR

Maximum power +19.5 =EIRP

EIRP = PT+G where PT and G are the transmit power and antenna gain respectively

The gain of antenna used was 19.5 and by decreasing the maximum transmit power at the

fixed gain the EIRP decreases, similarly increasing the maximum power increases the

antenna EIRP

TASK 8

The Common Pilot Channel (CPICH) is transmitted by a base station in each cell to make the

channel estimation possible. Therefore, the CPICH carries an unmodulated signal which is

spread at the spreading factor equal to 256 and is scrambled with the cell-specific scrambling

code. It has to be detected in the whole cell. Besides channel estimation, the CPICH channel

is used in measurements in handover and cell selection operations. Therefore, it has to be

broadcasted within the cell with high power.



- 30 -

Using maximum transmit power of 43dBm,

let X be the pilot channel power in mW.

Therefore 43= 10log(X)

X= Antilog (4.3)

X= 19952mW ≈ 20W.

This is comparable with the transmit power of the Vodafone Node B’s obtained from the site

finder as shown in Table.4 above.

TASK 9

Information carried on PCCPCH

Primary Common Control Physical Channel (PCCPCH) is the downlink physical channel that

carries the BCH (broadcast channel) in the downlink direction. The BCH channel is used to

send network and cell specific information to UEs in a cell.

The PCCPCH is transmitted with very high power from the base station to reach all terminals

in the cell. The PCCPCH is available in a way that all the terminals populated within the cell

coverage are able to demodulate its contents.

The PCCPCH uses a fixed channelization code and thus its spreading code is fixed. This is a

must because otherwise the terminals will not able to "see" and demodulate the PCCPCH.

The PCCPCH bit rate is 30 kbps with a spreading factor value of 256. The bit rate must be

low because this channel is transmitted with relatively high power. If using higher bit rates,

the interference starts to increase thus limiting the system capacity.

There is only one Primary Common Control Physical Channel within a cell, and it is used to

carry synchronization and broadcast information for users

TASK 10

Information carried on SCCPCH



- 31 -

The Secondary Common Control Physical Channel (SCCPCH) carries two transport

channels, the Paging Channel (PCH) and Forward Access Channel (FACH). The bit rate of

SCCPCH is variable bit rate and fixed spreading factor is used. PCH carries pages from the

base station to UE. While FACH sends information to a UE after the UE makes a random

access attempt on the PRACH uplink physical channel. SCCPCH contains no power control

information.

TASK 11

CELL COVERAGE AND ANTENNAS

Signal coverage can be predicted by coverage prediction models and is usually applied to a

start-up system. The task here is to cover the whole of area of Oxford city, approximately

45.5 km2

and population of about 165,000 people with a minimum number of cell sites. The

cell sites must be engineered so that the holes are located in the no-traffic locations. The

service areas as occurring in one of the following environments have to examine:

Human-made structures

In a building area

In an open area

In a suburban area

In an urban area

INITIAL COVERAGE DEPLOYMENT

The coverage deployment was started with twelve (12) Node Bs as shown in fig.16 (8 three

sectored, 1 two sectored and 3 six sectored). After initial deployment, a lot of patterns

overlaps among the neighbouring cells were observed. For instance where sector 1 of Node A

overshoot to Node B, Node C and Node D. similarly, sector 2 of Node A overshoot to Node

B, Node E and Node F. In location F also the boundary between Node G and Node H patterns

was not clearly defined, as they overlapped.

Also gaps were observed in some places such as in location Q and L. The terrain of the area

is responsible for the coverage gap, which is a hill about 93m high above the sea level at

location Q. Node I (at location, 001014’17.92’’W, 51

046’28.58’’N) with 15m height the Node

B was meant to serve the site including Northern bypass road. Measuring the height profile

between the Node B and some locations on the Northern bypass road (e.g. location D) there

was no fresnel clearance to the road with LOS obstruction of 3.9m as shown in fig.18 Below.

The same thing happened at location E. This is because of the present of hill in the area with

elevation of about 108m above the sea level.

Another issue was the received signals along some part of the boundaries such as locations A,

B, C, D and E shown in the fig. 16 which was observed to be below the signal threshold

(minimum receiver sensitivity).



- 38 -

The coverage percentage was found to be 70.245%, which was a bad coverage and not

optimum enough to provide coverage to all residence and the motor ways. Therefore, various

optimisation techniques needed to be employed in the network coverage deployment to

increase the percentage coverage and to reduce the interference in the neighbouring cells.

COVERAGE OPTMIZATION

EFFECTS OF ANTENNA HEIGHT ON THE NETWORK COVERAGE

The antenna height play an important role in network coverage, as the height of the antenna

must be carefully optimized to improve coverage and signal strength due to the nature of the

terrain.

The effects of antenna height on the coverage using six sectors antenna was studied and

analysed using antenna height of 20m and 25m and bar chart was drawn as shown in fig 19 &

20 below. The table 8 below shows the increase in the percentage coverage with increasing

antenna height. The same procedure was used using three sectors antenna. The height of the

antenna was varied from 15m to 20m and bar chart plotted shows the increase in coverage

percentage with increasing the antenna height.

Observed from the table 8 above that as the height increases from 20m to 25m the corresponding

network coverage area increases from 30.85 (72.90%) to 32.42 (76.60%) therefore, the coverage area

percentage increased by 6%. Bar chart representation of the table is shown in Fig 19 & 20.

provide a coverage of 81.93% therefore it clearly shows that network coverage increase with

an increase in antenna height. Similarly for the same display area, 20m three sectors antenna

provides better coverage than 20m six sectors. The bar chart shows the representation of the

EFFECT OF MECHANICAL DOWN TILT (MDT) ON THE PILOT COVERAGE

The impact of MDT on the coverage has been studied using three and six sectors antenna.

The main aim of this is to provide answers to two main questions

1-On how to select the down tilt angle of the NodeB

2-What are the impacts of antenna down tilt on the network coverage.

Using fixed EDT of 60, the effect of MDT on the network coverage was investigated as

shown in the table below

Fig .23 showing the effects of MDT on coverage at different heights for three and six sectors antenna

From table 10 above, the MDT decreases the coverage area but it tends to reduce overlaps of

the pilot signal form neighbouring cells which reduce other cell interference in the main lobe

direction. The bar chart shows the representation of the table. Similarly the effect of MDT

and Heights on received signal and distance was also investigated; the graphs showing the

effects can be found in Appendix A.

FINAL COVERAGE DEPLOYMENT

From the above studies (Effects of antenna height and tilting on the coverage); it was found

that the percentage coverage can be improved with increasing the antenna height and by

adjusting the antenna mechanical down tilt specific areas can be served to prevent overlaps of

the pilot signals in the coverage. The initial deployment above was optimised by increasing

the various antennas height and adjusting the antenna mechanical tilt down where

appropriate.

Since the initial deployment percentage coverage recorded was only 70.245%, to improve the

coverage, additional two (2) Node Bs were employed to make the total number of Node Bs in

the network to be fourteen (14) as this was the number of Node Bs required based on the



- 46 -

estimation obtained above in the coverage dimension analysis, and Node C (six sectored

antenna) in fig. 16 was replaced by three sectored antenna because Node C could not provide

enough coverage for both residence and the motor way (Northern bypass road), the

population and expected traffic is not large to necessitate six sector deployment.

As an example to the methods employed to improve the coverage, the problem recorded

during initial deployment where obstruction observed from Node I base station to the

Northern bypass road was solved by increasing the node B height to 25m instead of 15m that

was initially used. The height profile after increasing the base station height is shown fig. 24

below with the LOS clearance of 8.9m, when measuring distance up to 1km away from the

node B.

Fig 24: showing LOS clearance

Height profile measurements was undertaken to make sure there is Fresnel clearance from a

given Node B to any point within the area intended to be served by the Node B. Some figures

category 1 ( i.e. category with very low signal level below the threshold, see Appendix B for

the category ranges). The least coverage percentage was 99.88% with 0.66% in category 1 for

Node 15A, the cell in three sectors antenna at coordinate (0010 12’ 24.01”W, 51

0 44’

50.26”N) aimed to provide coverage to the residential area along the Hollow away Rd, the

other sector provide coverage to the eastern bypass Rd. This problem could be as the results

of the terrain of the area as shown in the fig. 35 below which shows the presence of high hill

by 72.5m LOS obstruction just 90 meters away from the main road. So the Node B is not

serving the total area. Our aim is to serve up to the road not beyond and is achieved as shown

in fig. 34 with Fresnel clearance of 15.6m from the Node B to the road. Similarly Node 3A

gives coverage of 99.96% and 0.20% in category 1 this may be as the results of hill 780m

away from the Node B which block some of the signal from reaching target area as shown in

fig. 36 below.

CONCLUSION

Network coverage planning is essential part of 3G networks, in this report 3G network

coverage for oxford city was design.

The effect of antenna height and tilt on the signal level and coverage was studied to optimize

the performance of the network parameters so as to achieve good coverage it was found the

network coverage and signal strength increases as the height increase. And the tilt tends to

decrease the overlaps of the pilot signal

After deployments the total displayed area was 57.446km2

and the total covered area was

57.428km2

with coverage percentage of 99.96%.

Apart from small discrepancies observed, the deployed coverage provides very good

coverage with very good defined boundaries. Due to the different terrain in different areas the

percentage coverage of individual Node B varies. The pilot power received at any point

throughout the total coverage area is within the acceptable range

Based on the figures in Appendix A, the total power received 1km away for each Node B was

very good and the Ec /Io for each sectors are still good to maintain call 1.2km from each

NodeB.
