Signal strength in the tested area on idle mode is good with the average RSCP(3G) -85.79 dBm & Rxlev-80.34dBm,

Signal quality is excellent with the average RxQual value 0.89.

EcNo value is low, with the average of -9.38 which means that the signal quality is good.

There is only 1 call drop on 2G and 1 call drop on 3G

Overall Signal strength & Signal quality is good

Bad Spot Reamrk/Area of Optimization:-

Need Site Audit & Physical Optimization for JKP100E, with Ant Height : 21, Azimuth : 70, M Tilt : 4, E tilt : 2. 8Please

Up tilt the mechanical from 4 to 0 & Down tilt the electrical from 2 to 8.

Need Site Audit & Physical Optimization for JKP044 and swap sector JKP044B & JKP044C.

Site BGR018 is down so EcNo & RSCP are very bad & served from far neighbors site (BGR012F, BGR020G,

BGR076G, BGR017G).

Site KDP004 is down so EcNo & RSCP are very bad & served from far neighbors site (KPD003G, KDP015G,

BGR013G) performance BGR018 & KDP004 on May 26, 2012

EcNo & RSCP are very bad because no dominant serving cell, . Need Site Audit & Physical Optimization for

JKS155E. Please Up tilt the mechanical from 3 to 0 & Down tilt the electrical from 0 to 5

EcNo & RSCP are very bad because no dominant serving cell, . Need Site Audit & Physical Optimization

for JKS155E & JKS171G. Please re-azimuth JKS171G from 270 degree to 300 degree EcNo & RSCP are very bad because no dominant serving cell, Need Site Audit & Physical Optimization

for JKS165 & JKS069. Please re-azimuth JKS069G from 300 degree to 270 degree.
