Also. we used a set of drive test equipment with GPS and Sony Ericson W995 (TEMS) mobile station in the test car. 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. 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 . the test result will help provide an understanding of network reliability and performance. and a laptop computer installed with data collection/analysis software (TEMS Investigation).2 Test method and Test Route For the drive test. Both are used to define the forward coverage range of the system. For better detailed network information according to BTS distribution and landform. to maintain a profitable customer base. The two mobile stations were set for both long call and short call respectively at full rate. 2. The MS was used to test Rx_level (received power) and the Rx_Qual (Speech/Voice Quality).

FINCON Drive Test Engineer: Alozie Charles Date: 12/03/2014 Supervisor: Jude Abba fincon . C. 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. 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. they are experiencing very poor network coverage. Areas marked D. B.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. Areas marked A and C has a poor coverage because of the dense vegetation and has no settlements. It can be clearly seen that the received power is not impressing especially for the marked areas. D. E. Hence no optimization is required for these areas. E and F . As indicated in the figure for areas marked A. 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.

transmission back bones as well as resources for calls. the following steps can be taken for the optimization plan. 4. and F in the RX_LEVEL diagram should be down tilted by an angle of two degrees below so as to increase network coverage. to ensure consistency in good network performance. SQI. must be in good status so as to maintain an excellent Rx_level. E. call setup ratio etc.1 OPTIMISATION PLAN From the above analysis. a neighbor cell (Site 1_ sector2) should be configured on site3_ sector1 in order to avoid forward interference. except for some areas that are having poor signal receivedlevel due to thick vegetation surrounding the areas and distances.
