GL Communications has announced 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 bandwidth—up 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 network".

Main Features

• 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 captured data
• 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 spreadsheet
• 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
