Press Release: GL Announces LTE (Long Term Evolution) Protocol Analyzer
Gaithersburg, Maryland, USA - May 14, 2010 - GL Communications Inc., announced today the release
of its latest product in the protocol analyzer series LTE (Long Term Evolution) Protocol Analyzer software. Addressing
the press conference, Mr. Karthik Ramalingam, Project Manager at GL, said, "LTE (Long Term Evolution) protocol
standard is the so called 4G (4th Generation) mobile standard in the rapidly evolving mobile technologies. Its
distinguishing feature is an all IP infrastructure and significantly greater air interface bandwidth to the mobile handset.
It was developed as an enhancement to the existing 3G UMTS System (Universal Mobile Telecommunications System)
to provide users enhanced mobile radio and internet access".
He added, "The LTE air interface is a completely new system based on orthogonal frequency-division multiple
access (OFDMA) in the downlink and single-carrier frequency-division multiple access (SC-FDMA) in the uplink. The
system efficiently supports multi-antenna technologies (MIMO). OFDMA is considered much better at handling the
varying propagation conditions seen in mobile radio. This is similar to WiMAX. In MIMO techniques, either multiple
antennas can transmit the same data stream to improve data-transmission reliability or different antennas can
transmit different data streams simultaneously to increase throughput. And another significant feature of LTE is its
high bandwidthóup to 20 MHz. Because the usable bandwidth is scalable, LTE can also operate in the existing
5-MHz UMTS frequency bands or in even smaller bands".
Mr.Ramalingam further added, "GL's LTE analyzer is capable of capturing, decoding and performing various test
measurements across various interfaces i.e. S1, S3, S4, S5 (or S8), S6a, S10, S11, S13 and X2 interfaces of the LTE
- Displays summary, detail, hex-dump, summary and statistics views
- Detail View displays decodes of a user-selected frame from the Summary View
- Statistics View displays statistics based on frame count, byte count frames/sec, bytes/sec etc for the entire
- Hex dump View displays raw data as a hexadecimal and ASCII octet dump
- Search and filtering capabilities
- Exports Summary View information to a comma delimited file for subsequent import into a database or
- Capability to export detailed decode information to an ASCII file
- Remote monitoring capability using GL's Network Surveillance System
Additional feature supported by Offline LTE Analyzer
- Trace files for analysis can be loaded through simple command-line arguments
- Multiple trace files can be loaded simultaneously with different GUI instances for offline analysis

About GL Communications Inc
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM,
Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture,
storage, and convenient features like portability, remotability, and scripting.
GLís TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire,
and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband
traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303,
Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products
provide astonishing capacity and capture capability up to and including gigabit speeds.
GLís VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as
frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729,
AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording.
The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput
parameters of Ethernet and IP networks, including delay, errors and other impairments.
GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS,
PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice
Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.
GLís Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE
networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal
GLís Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic
echo. GLís compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted
in the industry.
GLís wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice
compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and
other distortions are easily assessed and accurately measured.
GLís Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional
T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers
provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1,
T3, E3, and many others.
GLís Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An
open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized
or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based
