  • 9. GSM / EDGE / WCDMA Product Overview 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. Copyright © X-TEL Communications, Inc. 2007 Page 9
  • 10. GSM / EDGE / WCDMA Product Overview X-2 GSM Scanner with BSIC Decoding The X-2 GSM BSIC Scanner is a DSP-based software radio that provides unparalleled precision and user-defined options for the measurement of GSM signals across 850 MHz, 900 MHz, 1800 MHz and 1900 MHz networks. X-2 WCDMA Scanner The X-2 WCDMA Scanner provides SCH, CPICH and PCCPCH scans to measure Eps/I0 and Ess/I0 for the synchronization channel, Ec/I0 for the pilots in the CPICH and Epc/I0 for the specified scrambling codes in the Primary Common Control Physical Channel. Portability and In-Building Collection The GSM/WCDMA system combines in-building data collection with vehicle data collection system. The user can import floor plans using a variety of file formats such as TIFF, DXF, JPEG and others. For in-building collection, simply pick a starting point and an ending point on the floor plan and data is mapped in the same manner as drive test data. For the first time ever, full drive test functionality and in-building data collection is integrated into one test tool, without sacrificing features and functionality. Copyright © X-TEL Communications, Inc. 2007 Page 10
  • 11. GSM / EDGE / WCDMA Product Overview 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. Copyright © X-TEL Communications, Inc. 2007 Page 11
  • 12. GSM / EDGE / WCDMA Product Overview Engineers can use the X-TEL GSM/WCDMA Xi software to playback test data collected in the field. The map, graphs, charts and other displays viewed during playback function the same as in real-time. In addition, the speed of the playback is adjustable, which offers engineers more control in post data collection analysis. Engineers can also use the right and left arrow keys on the computer keyboard to step back in 2-second increments or to step forward data point by data point. By changing the location marker, engineers can scroll either forward or backward within the data file to look at all information collected during the drive test. Phone Status Display The X-TEL GSM Real-Time Display is one of the most flexible software applications ever developed for data collection, display and analysis. Displays include bar graphs, moving maps with data attributes, charts and other color-coded displays for viewing of system specific parameters. Unique user profiles allow display windows to be configured according to individual preferences. Windows can be sized and customized creating a virtual drive test dashboard of detailed attributes relating to real-time system performance. WCDMA Intra Status Screen The X-TEL WCDMA Intra Status screen includes Phone Task Description, Channel Mode Status, UARFCN, Primary Scrambling Code, UTRA RSSI, Target SIR, TX Power and other key parameters.

  • 14. GSM / EDGE / WCDMA Product Overview 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. Copyright © X-TEL Communications, Inc. 2007 Page 14
  • 15. GSM / EDGE / WCDMA Product Overview The pilot pollution type 3 (PP3) above was triggered because the Ec/Io difference between the first SC of the Active Set was within 5 dB of the third SC of the Active Set. The threshold is user selectable for PP3. Pilot Pollution Type 4 The pilot pollution type 4 (PP4) above was triggered because the Ec/Io difference between the first SC of the Monitored Set was within 5 dB of the first SC of the Active Set. The threshold is user selectable for PP4. Copyright © X-TEL Communications, Inc. 2007 Page 15
  • 16. GSM / EDGE / WCDMA Product Overview Pilot Pollution Type 5 Pilot Pollution Type 5 is defined as the Ec/Io difference between the 5th and 6th strongest SC being a user defined difference (8 dB by default). Copyright © X-TEL Communications, Inc. 2007 Page 16
  • 17. GSM / EDGE / WCDMA Product Overview 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. Copyright © X-TEL Communications, Inc. 2007 Page 17
  • 18. GSM / EDGE / WCDMA Product Overview Layer 3 Message Display Layer 3 information is logged and presented in real-time and during playback for both GSM and WCDMA networks. Simply select the message of interest and double click to decode the message. Examples of both GSM and WCDMA messages are below. The L3 Filter and Search utilities allow users to select the specific L3 messages they wish to display during data collection and those they wish to find after data collections, respectively. This powerful feature allows the user to concentrate only on specific messages of interest, failed hard handovers, for example. Copyright © X-TEL Communications, Inc. 2007 Page 18
