Our company specialized in radio telecommunication puts underyour 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 Cellshould 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

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 UElocked in 2G mode
Mobile originated calls, Mobile terminated calls, EDGE FTPDownload, EDGE FTP Upload
For 3G Service Check, we are able to do the following tests using aUE locked in 3G mode
AMR originated call, AMR terminated call R99 FTP download, R99 FTP Upload HSDPA FTP download and HSUPA FTP Upload

For 2G Service Check, we use 2 UEs and one GPS in order toexecute the long and short calls tests.
For 3G Service Check, we use 2 UEs in order to execute the AMRlong 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, its possible to perform Drivetest in global area in order to optimize the radio performance (detectcall drops, Handover Failures, Call set up Failures and resolve theseproblems)
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
