Introduction:

Objectives:

The purpose of the drive test to perform the RF design verification, identify any coverage and quality problems to optimise WCDMA network performance.

At this stage, the main focus is on fundamental end-to-end service accessibility target (e.g. Calls set up and drop rates) and on performance targets such as coverage related targets (such as CPICH RSCP and CPICH Ec/No), and HSDPA/HSUPA speed performance.

For this case it was needed each other from drive test data collection and also Physical site changes like tilting, antenna orientation and antenna height.

RF Solution Department

Drive Test Equipment• Drive test Tools ,UE’s, Scanner and GPS can be used

– The Scanner measures all used carriers/cells and their corresponding DL scrambling codes,

– UE only measures SC signals from the cells that the system has informed/ordered the UE through the BCH (neighbour list) or via the “measurement control” msg.

UE: • RSCP Active/Monitored Set• Carrier RSSI• Ec/No Active/Monitored Set• UL/DL Data Throughput• The BLER downlink• Random Access Initial Tx Power• Random Access Preamble Count & Step• SIR target (UE dependent)• UE Tx Power • Call Statistic: AMR, CS and PS data calls• CQI• Modulation techniques

Scanner:• For low coverage areas• For Antenna Installation problems• For Missing neighbours• For Coverage optimisation• With Scanner you can get following info

from the surrounding cells:– Different Scrambling codes– CPICH RSCP value (dbm)– CPICH Ec/No value (dbm)

Important to drive with call logging equipment and 3G/2G scanner in the same van
