Key Benefits Modularity The X-TEL GSM/WCDMA system supports a wide range of phone technologies. These include support for test mobiles across TDMA, GSM, GPRS, EDGE, CDMA, 1XRTT, WCDMA/HSDPA and iDEN technologies. X-TEL also supports industry grade dedicated scanners for TDMA, GSM and WCDMA. Its sophisticated internal bus architecture supports up to 26 ports for system expansion. An easy to use plug and play platform allows engineers to change phone and scanner configurations based on their technology requirements. The cost of upgrading and expanding the HCU platform is very economical when compared with other test systems in the industry. Real-Time Display The X-TEL GSM/WCDMA system is easy to operate and offers the flexibility of choosing parameters that are of interest to engineers to display on the map in real-time. With just the click of a button, the real-time map can be configured to display different phone and cell site attributes, allowing engineers to make critical decisions faster. Street networks from any MapInfo compatible source can be loaded and displayed to further assist engineers with troubleshooting problem areas. Along with the real-time map display, user configurable graphs, charts and text displays of GSM and WCDMA parameters are tailored to assure easy understanding. Playback Mode Engineers can use the X-TEL GSM/WCDMA system to playback test data collected in the field. Maps, graphs, charts and other displays viewed during playback function the same as in real-time. The speed of the playback is adjustable, offering engineers more control in post data collection analysis. Other controls allow the user to jump forward and backward to specific data points within the playback file. Audible alerts are active during playback, just like in real-time. Rush Street Mobile provides additional playback features such as synchronizing all display windows to play back data based on user defined criteria like low signal strength, pilot pollution or dropped calls. Rush Street Mobile Engineers can now analyze data in the field without the need to return to a central post processing location. Rush Street adds several advanced real time features such as plotting multiple devices during data collection. For example, engineers can view and plot both their GSM and WCDMA test phones during data collection. For GSM only networks, the engineers can plot multiple metrics such as RxLev and RxQual during the drive test. Engineers can also define Boolean expressions to search for specific events such as dropped calls, poor signal strength and others. Rush Street Mobile then presents a plot of only those points that match the criteria. Once plotted, the engineer can click on any point to replay the drive from that location. All open windows synchronize to the selected location to assist in troubleshooting. Rush Street Mobile increases productivity of engineers because decisions can be made in the field. Post Processing Fast, reliable post processing of data integrated into MapInfo is yet another reason why the X-TEL GSM/WCDMA system is so popular with users today. Drive test map generation can be performed in the field or at the office. It is fully automated with customizable map attributes and layouts. Hundreds of maps can be generated quickly with little effort or training. Advanced analysis tools include dB Adjust to dynamically change signal strength of one or more channels and then see the effects on best server maps. This tool is ideal for performing “what if” scenarios for new sites with test transmitter data.

Real-Time / Playback Data Display

The GSM/WCDMA Real-Time / Playback map display accurately depicts vehicle position, cell locations and local streets. The vehicle path can be configured to display critical GSM/WCDMA parameters such as RSSI/RxLev or FER. Or display WCDMA parameters such as the primary and secondary scrambling codes, primary CPICH Ec/I0 and UTRA carrier RSSI. The color of the path drawn is also user configurable, providing another convenient way for these parameters to be viewed. Rush Street adds to these capabilities by allowing the engineer to view multiple phones and parameters simultaneously.

Events such as handovers, call origination, call termination and dropped calls will be displayed along the path drawn using user defined colored symbols. The blue arrows in the window above indicate locations where a handover occurred. Neighbor lines are drawn from the vehicle position to serving cell sectors, easily identifying the current serving sector(s). Cyan and yellow lines will be drawn to the strongest and second strongest neighbor, respectively. Anytime a neighbor is stronger than the serving sector, the lines and bar graph in the MAHO Status Screen become red.

WCDMA Pilot Pollution Analysis X-TEL includes five classes of pilot pollution; four based on information from the mobile and one based on independent scanner measurements. The five pilot pollution classes are presented below.

Pilot Pollution Type 1 The first type of pilot pollution (PP1) is defined when a SC Ec/Io is less than a given threshold and the RSCP is more than a defined threshold. These are user defined with defaults set as Ec/Io less then -10 dB while RSCP is more than -85 dB.

Descriptions and examples of pilot pollutions types 2, 3 and 4 follow.

Pilot Pollution Types 2 and 3

The pilot pollution type 2 (PP2) above was triggered because RSCP was more than -85 dB for more than 2 of the Scrambling Codes. The RSCP and quantity thresholds are user definable for PP2.

GSM and WCDMA Missing Neighbor Analysis X-TEL supports missing neighbor analysis for both GSM and WCDMA network testing. Information from the scanner is compared in real time to neighbor information reported by the test mobile. Missing neighbors are user defined based on signal level and proximity.

Missing Neighbor Example

Missing Neighbor: In this area, the phone is not reporting SC 347 as a neighbor, but the WCDMA scanner reports that SC 347 is within the search proximity and greater than the minimum level defined for a neighbor. There is only one active set SC so SC 347 is a potential missing neighbor.

Seek Playback – Synchronized Analysis The Seek Playback feature will synchronize all open analysis windows to the specific point chosen with Seek Playback. Once the event is selected, all windows synchronize and the data file begins playback 2 seconds prior to the selected event. Playback will begin at normal speed to allow the engineer to troubleshoot specific events like multiple handoffs, dropped calls or failed handovers. Using the right and left arrow keys on the keyboard the engineer can step forward data point by data point or backwards in 2-second intervals, respectively.

Seek Playback is a powerful analysis tool that allows detailed playback of specific events at a user controlled speed. One important aspect of Rush Street is the ability to perform detailed analysis in the field. There is no need to return to a central location for traditional post processing that can often be cumbersome and inefficient.
