Complete uplink and downlink transfer characteristics are collected and compared with mobile RF system performance. Simultaneous GPRS testing, along with GSM RF performance parameters can be measured, displayed, replayed and plotted for optimization purposes.

X-TEL’s GSM/GPRS in one of the first drive test systems to support GSM/GPRS system testing for North America. Utilizing multiple phone options, performance data can be measured for any 850, 900, 1800 or 1900 GSM systems worldwide.

In addition, X-TEL supports interfaces to some of the most popular GSM subscriber performance mobiles like the Nokia 6190. For example, by using performance mobiles like the Nokia 6190 configured alongside a GPRS test mobile, detailed GSM/GPRS data is measured simultaneously with performance data. This enables companies to effectively engineer GPRS into their networks, while simultaneously monitoring performance data using the same mobile many of their subscribers are using. We think this approach is unique and is another reason why more and more markets are turning to X-TEL's modular and scalable solution for their test equipment needs.
