2 ProcedureThe procedure for the drive tests is described below:

Cluster drive tests shall perform 3 call scenarios: short call, long call, and PS call. GPRS functionality drive tests were performed by downloading a huge file from an FTP server throughout the cluster drive test route. Configuration of MS is as follows in the DT Kit:

MS1= Long call (MS to MSC Test Number ,continous call )

MS2 = Short call (MS to MSC Test Number, 30sec., 3 sec. delay)

MS3 = EGPRS downloading

MS4 = Idle

GPRS was not connected in Gandhinagar site & Muvattupuzha site’s 2nd sector, informed to OMCR.

5 Recommendation & Technical Overview

In this cluster most of the places having terrian issue(Hilly terrian) We couldn’t able to change the azimuth of Muvattupuzha site’s 3rd sector, due to another

antenna obstraction. There is an over shoot from Muvattupuzha site , On 3rd sector mainlobe of Gandhi

nagar,Because Gandhi Nagar Site’s antenna height is 40m and Muvattupuzha site’s antenna ht is 49 m and sharp variation in AMSL also.

We have attached the radiation patterns for the issue sites. Muvattupuzha 3rd sector antenna photo:
