Press Release: GL Announced today its Wireless Protocol Analysis, Simulation and VQT products
at CTIA Wireless 2007!
Gaithersburg, Maryland, USA - April 5, 2007 - GL Communications Inc., announced today its Wireless Protocol Analysis,
Simulation and VQT products at CTIA Wireless 2007! 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 VQuad™ 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
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.
About GL Communications Inc
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless,
and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and
convenient features like portability, remotability, and scripting.
GL's TDM Analysis & Emulation line of products includes T1, E1, T3, OC-3, STM-1, analog four-wire, and analog two-wire
interface cards and solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits,
tones, fax, modem), all protocols (HDLC, ISDN, SS7, CAS, GSM, GPRS, CDMA), and with capacities up to thousands of channels.
GL's VoIP products generate / analyze thousands of calls simultaneously with traffic types such as voice files, digits, tones,
noise, and fax using G.711, G.729, AMR, EVRC, and GSM codecs. Additional features include visual analysis, real-time listening,
recording, and voice quality assessment using ITU algorithms PAMS, PSQM, and PESQ.
GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and CDMA 2000
networks. Connections can be made to any wireless phone with automated call control, GPS, mapping software, and real-time
GL's Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing
per G.168 and G.160.
GL's Network Surveillance and Monitoring products include Probes for TDM, VoIP, ATM, and Wireless networks. An open
standards based approach provides a scalable, feature rich, real-time access to network intelligence. Centralized or
distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring
