4 Conclusion and suggestion

Coverage Summary

Site ID Site Name Town(s) Covered Coverage Statistics Meet CoverageCriteria (Yes/No)

RV0151 Ndashi Ndashi Better than -85dBm = 96.73% Yes

The site has a wrong coordinate. The correct coordinate is N7.109725 and E5.208641.

Most of the roads in the village were in accessible due to obstructions (forest and farmland) at

the time of drive test, but CQT was done in all directions of the village to confirm coverage.

Both RX_Lev and RX_Qual are good.

Silent calls were noticed throughout the CQT.
