Press Release: GL Participates in recently concluded CTIA Wireless 2008 at Las Vegas, USA

Gaithersburg, Maryland, USA - April 18, 2008 - GL Communications Inc., announced today, its participation in recently concluded CTIA 2008 exhibition in Las Vegas, NV, USA. Speaking to the media, Mr. Jagdish Vadalia, senior manager at GL said, "We demonstrated at the show, GL's test and measurement equipments that provide support to Wireless Protocol Analysis and Simulation. They included, CDMA 2000, UMTS, TRAU, GSM, and GPRS Protocol Analyzers, Simulators and Emulators. Our VoIP and TDM Protocol Analyzers & Simulators compliment the Wireless tools to provide a complete network monitoring solution".

He added "GL's test tools can also serve the wireless network providers and equipment manufacturers who are 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 impairments."

Mr.Vadalia, further added, "We like to thank all who have visited GL's stall and showed an interest in knowing about GL's test and measurement products during the show".


Brief description of GL's latest Wireless products displayed during the show:

Wireless Protocol Analysis and Simulation Products

  • Emulate and Analyze TRAU traffic at Abis interface with various Codecs such as AMR, FR, HR, and EFR

    TRAU carries speech, data, O&M frames at full rate or half (8/16 kbps) rate and control information, over T1/E1 in a GSM network. GL's T1/E1 Analyzer can be equipped with TRAU ToolboxTM, TRAU Traffic Playback, and TRAU Analyzer applications for emulation and analysis of traffic at Abis interface (BTS to BSC), and A-ter interface (BSC to MSC) interfaces.

  • 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 Center), 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 interfaces

    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.

  • 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.

VoIP Analysis & Emulation (SIP, RTP, RTCP, MEGACO, MGCP, Video, H323)

  • A single-box solution to simulate an entire IP network
  • Capture & segregate live IP traffic
  • Test IP phones, Gateways, IP Routers and Switches, and Proxies
  • Bulk call generator for stress testing and precise analysis

TDM Analysis & Emulation (T1, E1, T3, OC-3, STM-1)

  • All traffic types (Voice, Digits, Tones, Fax, Modem)
  • All protocols (HDLC, ISDN, CAS, SS7, MLPPP, GR303, ATM, ...)
  • Real-time signal measurements, and automated call control

Voice Quality Testing Solutions

  • VQuad™ - VQT Solution
    • Low Density Network - Low Cost
    • Uses Intrusive T1E1 (PRI ISDN, CAS), VoIP (SIP, RTP, H323), Wireless (Mobile Phones, Radios, GPS), & Analog Probes (2-Wire) with VQuad™-VQT software
    • VQT measurements using PESQ, PAMS, and PSQM
    • Remote Control and Monitoring System with Regional Command Center & Remote Client NetViewer™
  • VBA (Voice Band Analyzer) Solution
    • High Density Network - Scalable Network Solution for detail analysis
    • Uses Non-Intrusive T1E1, VoIP, Wireless, & Analog Probes with VBA software
    • Remote Monitoring System with VBA WebViewer™
