Introduction
Our company specialized in radio telecommunication puts under your disposition our skills and experiences concerning: - Site verification radio parameters - Drive test data - Analysis and recommendations in order to optimize the performance of our network
We perform testing for 2G and 3G networks (GSM/GPRS/EDGE/ UMTS/R99/HSDPA/HSUPA)
We use Nemo tools in drive test data

Site verification of radio parameters (1) Hardware Checking
For each cell, we choose one location close the BTS. The target Cell should be in the Light of Sight. The following items should be checked approximately:
Antenna Azimuth Antenna Tilt
Note: This test should be repeated for each Sector

Site verification of radio parameters (2) Network Checking
For 2G Network Check, we could collect the information below using an IDLE UE locked in 2G mode :
Frequency BCCH BSIC Cell ID LAC/RAC
For 3G Network Check, we may collect the information below using an IDLE UE locked in 3G mode :
Frequency Primary Scrambling Code Cell ID LAC/RAC

Network performance checking in static positions
For 2G Service Check, we could do the following tests using a UE locked in 2G mode
Mobile originated calls, Mobile terminated calls, EDGE FTP Download, EDGE FTP Upload
For 3G Service Check, we are able to do the following tests using a UE locked in 3G mode
AMR originated call, AMR terminated call R99 FTP download, R99 FTP Upload HSDPA FTP download and HSUPA FTP Upload

Network performance checking in mobile positions
For 2G Service Check, we use 2 UEs and one GPS in order to execute the long and short calls tests.
For 3G Service Check, we use 2 UEs in order to execute the AMR long and short calls and data transfer. Note: the test should be made Clockwise and anti clockwise

Area Drive test verification After site verification of radio parameters, it’s possible to perform Drive test in global area in order to optimize the radio performance (detect call drops, Handover Failures, Call set up Failures and resolve these problems)
For 2G Service Check, the following tests will be considered: 2G Long and Short call Automatic Long call (2G and 3G) EDGE FTP Download MOS For 3G Service Check, the following tests will be considered: 3G short and Long call R99 FTP download HSDPA & HSUPA FTP transfer MOS
