Air Interface Testing

We can provide car-mounted and portable test equipment that operates across all of the following technologies:

• GSM/GPRS/EDGE
• UMTS/HSPA
• CDMA2000 1XRTT/EV-DO
• GSM-R

From a subscriber perspective QoS measurements include real speech and video quality, drop call rates, failed call rates, SMS/MMS/Email success rates and delivery times, FTP/UDP/HTTP throughputs and other IP-Data parameters.

The engineering view delivers detailed air interface information like signal strength, signal quality, interference, serving/neighbor cells, layer 3 messages and additional measurements, invaluable in trouble shooting and network optimization.

These test units are complemented with a hand-held smartphone solution that can be deployed for autonomous and semi-autonomous applications.

Post-Processing of Data

We are able to provide post-processing solutions that can import data from drive test tools such as TEMS, NEMO and QVoice. L3 message views are standard but with intelligent diagnostics, optimization engineers are immediately provided with a clear view of the QoS issue and L3 analysis at the click of a button.

KPI Reports can be automatically generated as are key coverage and analysis plots. Our solution incorporates smart algorithms to detect swapped antennas, pilot pollution, overshooting cells and missing neighbors. These advanced algorithms also trace back the root cause of dropped and blocked calls in the data.
