2.1 Test Original Intention

The motive for conducting Drive Test for the Huawei network in Umuahia Town, Abia State, is to

test for the coverage and the qualit of the network and consequentl !rovide solution to an

e"isting network !roblem that ma be affecting the efficienc of the network# Also, the test result

will hel! !rovide an understanding of network reliabilit and !erformance, and determining what

needs to be done to im!rove consumer e"!erience on the network, to maintain a !rofitable

customer base#

2.2 T"t #"th$( a%( T"t R$'t"

$or the drive test, we used a set of drive test equi!ment with %&S and Son 'ricson ())*

+T'S mobile station in the test car, and a la!to! com!uter installed with data

collection.analsis software +T'S /nvestigation# The two mobile stations were set for both

long call and short call res!ectivel at full rate#

The S was used to test 0"1level +received !ower and the 0"12ual +S!eech.3oice 2ualit#

Figure: RX_LevelSub Distribution Ma !n Umuahia Town

The above figure shows the forward coverage +0"1level of the network# /t can be clearl seen

that the received !ower is not im!ressing es!eciall for the marked areas#

As indicated in the figure for areas marked A, B, C, D, E and F , the are e"!eriencing ver !oor

network coverage#

Areas mared A and C has a !oor coverage because of the dense vegetation and has nosettlements# Hence no o!timi6ation is required for these areas#

Areas mared D, E, and F has a !oor coverage because of the Antenna Tilting and high

antenna height causing areas ver close to the site to have ver low signal strength#

b two degrees below and the antenna height should be reduced#

Area mared B has !oor coverage=s because of forward interference from Site 9 +sector >

which was not configured as a neighbor to the serving Site +sector 9 as shown in the figure

below#

4.1 O@TIMISATION @LAN

$rom the above analsis, and the suggested recommendations so as to im!rove the network

coverage in some areas, the following ste!s can be taken for the o!timi6ation !lan#

The antennas close to the area marked D, E, and F in the RX_LEVEL diagram should be

down tilted b an angle of two degrees below so as to increase network coverage#

Also for area marked B, a neighbor cell +Site 91 sector> should be configured on site1

sector9 in order to avoid forward interference#

4.2 SUMMARY AND CONCLUSION

$rom the analsis above, it can be inferred that most !o!ulated !arts of the ;it are well

covered b the Huawei 7etwork, e"ce!t for some areas that are having !oor signal received-

level due to thick vegetation surrounding the areas and distances#

$inall, to ensure consistenc in good network !erformance, all signaling links, hardware

equi!ment of the radio network, transmission back bones as well as resources for calls, must be

in good status so as to maintain an e"cellent 0"1level, 0"12ual, S2/, call setu! ratio etc# and

other alread established on-goingE measurement inde" for good network qualit
