Speaking to the media, Mr. Jagdish Vadalia, a senior manager at GL said, “GL has a range of products to support wireless protocol analysis and simulation. They include, CDMA 2000, UMTS, TRAU, GSM, and GPRS Protocol Analyzers, Simulators and Emulators”. Referring about the GL’s Wireless Voice Quality Product, he added, “In many cases, wireless network providers and equipment manufacturers have been in search for a way to quantify the impairments in a consolidated, unified, and "end-to-end" manner. GL's Automatic File Transceiver (AFT) software combined with GL's Voice Quality Testing (VQT) software permits this simple "end-to-end assessment" in an efficient, portable, and hassle-free manner. Results include Mean Opinion Scores (MOS), which provide an excellent overall measure of end-to-end voice quality and detailed measurements of specific impairments”.
GL’s latest products include:
Wireless Protocol Analysis and Simulation Products
• MobNetMon™ - “Over Air” wireless network monitoring and analysis GL's new product, MobNetMon™, permits automatic "off-air" monitoring of any GSM network directly from a Quad band wireless phone. Supports FSP, GPRS, and EDGE systems
• Emulate and Analyze TRAU traffic at Abis interface with various Codecs such as AMR, FR, HR, and EFR
GL's TRAU Analyzer is used to non-intrusively monitor TRAU frames at the Abis interface (between the BTS and the TRAU node at BSC / MSC). GL's T1/E1 Analyzer can be equipped with TRAU Toolbox™, TRAU Traffic Playback, and TRAU Analyzer applications for emulation and analysis of traffic at A-bis interface
• Monitor GSM interfaces A, Abis, B, C, D, E, H, J, Gs
GL's GSM Analyzer is used to analyze GSM protocols, a switching and signaling telecommunication protocol between MSC & BSC, BSC & BTS, MSC & HLR, MSC & VLR, etc. and operates on T1 & E1 channels
• Monitor GPRS/EDGE interfaces Abis, Gb, Gs, Gn
GL's GPRS Analyzer performs real time (and offline) analysis across the Gb (T1/E1) and Gn (Ethernet) interface. The companion GSM Analyzer can also monitor the Abis and A interfaces, simultaneously
• Monitor CDMA 2000 Networks across A1, A3-A7, & A11 Interfaces
GL's CDMA 2000 Protocol Analyzer can be used to analyze and view protocols across A1 (between Base Station Controller and Mobile Switching Centre), A3 and A7 (between two Base Station Controllers), A9 (between Base Station Controller and Packet Control Function), and A11 (between Packet Control Function and PDSN) signaling interfaces
• Analyze UMTS network across Iub, Iur, IuCs and IuPs
GL's UMTS analyzer is capable of capturing, decoding and performing various test measurements across various interfaces i.e. Iub, Iur, IuCs and IuPs interfaces of the UMTS network. In addition, it supports ATM as the transport layer. It helps in fault diagnosis and troubleshooting UMTS network.
Mobile Voice Quality Testing Products
• Voice Quality Drive Testing
GL's Wireless VQT Drive-Testing platform provides the capability to automatically analyze voice quality of wireless networks on the road, i.e. drive testing
• Automated Drive Testing with GPS mapping;
• Fully portable and self contained;
• Voice quality per ITU Standards (PESQ);
• Round Trip Delay Measurement.
The equipment associated with the GL Drive-Test solution can easily be transported within a vehicle… just plug into the cigarette lighter!! (for power) and start the test.
• VQuad™ - Voice Quality Testing Across All Networks
GL's VQuad™ makes assessing Voice Quality between and within differing networks easy, portable, and convenient. The system provides all necessary capability for automatic measurement of Voice Quality and QOS for any desired network including VoIP, TDM, Wireless, or Analog.
