The GSM/EDGE solution is an evolutionary system, enabling customers to upgrade or adapt to different technologies such as CDMA EV-DO, iDEN, WCDMA/HSDPA, etc. The GSM/EDGE has full capabilities for post-processing functions using a built-in playback mode as well as the advanced X-TEL Utilities integrated within MapInfo. X-TEL Utilities include automatic post-processing routines with cellsite database integration, data merging and reduction based on time and distance.

The GSM BSIC Scanner allows for fast scanning measurements of signal levels with BSIC decoding capabilities. Additional spectrum scanner options are also available, providing for a second level of spectrum analysis without sacrificing scan speed necessary for BSIC detection. Customers can configure the scanner devices depending on their specific requirements.

The moving map interface is observed in real-time and playback modes. It displays vehicle position, active serving base station, neighboring sites, and colored attributes depicting parameters, such as: hand-offs, dropped calls, RXLEV levels, RXQUAL and many more. The advanced capabilities of the real-time display with integrated mapping aids in rapid identification of missing neighbor sites, serving sectors with poor RXQUAL and RXLEV, and other performance related issues.

Real-time displays unique to the GSM//EDGE system include the GSM/EDGE Phone Status Window, the BSIC Scanner, additional GPRS layer messages and continued support for in-building collection and mapping. The GSM/EDGE Phone Status Window consolidates all the important GSM//EDGE parameters for determining system performance, including, information related to the band, block and channel quality.

X-TEL’s GSM/EDGE test mobiles provide real time performance data on both the uplink and downlink paths. Collect throughput metrics, coding schemes and layer 3 messaging using Xi’s automated FTP utility. Display all critical metrics in tables and in user-defined graphs.

EGPRS Throughput Metrics

The EGPRS Serving Cell Info screen displays GPRS/EGPRS specific parameters in tabular format. The downlink and uplink parameters are placed side by side for easy viewing. Parameters displayed include the actual time slots in use, the coding scheme in use for the uplink and downlink, RLC/LLC throughput and retransmission metrics.

The downlink and uplink GPRS data transfer screens display GPRS specific parameters in graphical format. The graphs depict the uplink and downlink RLC/LLC throughputs, RLC/LLC retransmissions, block error rate, allocated bandwidth and actual bandwidth used.

Automated FTP and FTP Displays

X-TEL includes an automated FTP session generator for continuous uplink and downlink measurements. Once the FTP server is selected, the engineer enables the link and opens the appropriate display windows. Data specific displays for FTP transfer include Uplink and Downlink Speed Charts, Uplink and Downlink Average Throughput Charts and a Speed Measurements Table.
