and determining what needs to be done to improve consumer experience on the network.Fincon drive test report for Huawei network existing network problem that may be affecting the efficiency of the network. Also. The two mobile stations were set for both long call and short call respectively at full rate. we used a set of drive test equipment with GPS and Sony Ericson W995 (TEMS) mobile station in the test car. to maintain a profitable customer base. Both are used to define the forward coverage range of the system. The MS was used to test Rx_level (received power) and the Rx_Qual (Speech/Voice Quality). 2.2 Test method and Test Route For the drive test. the test result will help provide an understanding of network reliability and performance. the drive test route used is shown in the figure below: FINCON Drive Test Engineer: Alozie Charles Date: 12/03/2014 Supervisor: Jude Abba fincon . and a laptop computer installed with data collection/analysis software (TEMS Investigation). For better detailed network information according to BTS distribution and landform.

D. FINCON Drive Test Engineer: Alozie Charles Date: 12/03/2014 Supervisor: Jude Abba fincon . Hence no optimization is required for these areas. C. As indicated in the figure for areas marked A. they are experiencing very poor network coverage. Areas marked A and C has a poor coverage because of the dense vegetation and has no settlements. E. Area marked B has poor coverage’s because of forward interference from Site 1 (sector 2) which was not configured as a neighbor to the serving Site 3 (sector 1) as shown in the figure below. Areas marked D. Optimisation recommended for these areas should be that the antennas should be down tilted by two degrees below and the antenna height should be reduced. B. It can be clearly seen that the received power is not impressing especially for the marked areas. and F has a poor coverage because of the Antenna Tilting and high antenna height causing areas very close to the site to have very low signal strength. E and F .Fincon drive test report for Huawei network Figure: RX_LevelSub Distribution Map In Umuahia Town The above figure shows the forward coverage (Rx_level) of the network.

Finally. and the suggested recommendations so as to improve the network coverage in some areas. call setup ratio etc. Also for area marked B. hardware equipment of the radio network. 4. all signaling links. E.Fincon drive test report for Huawei network 4. to ensure consistency in good network performance.1 OPTIMISATION PLAN From the above analysis. and F in the RX_LEVEL diagram should be down tilted by an angle of two degrees below so as to increase network coverage. it can be inferred that most populated parts of the City are well covered by the Huawei Network.2 SUMMARY AND CONCLUSION From the analysis above. transmission back bones as well as resources for calls. a neighbor cell (Site 1_ sector2) should be configured on site3_ sector1 in order to avoid forward interference. The antennas close to the area marked D. the following steps can be taken for the optimization plan. SQI. except for some areas that are having poor signal receivedlevel due to thick vegetation surrounding the areas and distances.
