The LTE (Long Term Evolution) protocol standard was developed as an enhancement to existing Universal Mobile Telecommunications System (UMTS) to provide users enhanced mobile Internet access. The evolved UMTS terrestrial Radio Access Network (RAN), abbreviated as E-UTRAN, is also known as LTE.

Although an evolution of UMTS (UMTS uses wideband code-division multiple access (WCDMA) for transmitting signals), 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) (DFTS-FDMA) in the uplink that efficiently supports multi-antenna technologies (MIMO).

This robust feature is useful when handling the varying propagation conditions seen in mobile radio.

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.

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.

Capabilities

• 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.

Supported Interfaces

GL's LTE analyzer is capable of capturing and decoding various interfaces i.e. S1, S3, S4, S5 (or S8), S6a, S10, S11, S13 and X2 interfaces of the LTE network. The protocols supported for decoding across all these interfaces are NAS, S1AP, X2AP, eGTP, Diameter, SCTP, UDP, TCP, IP.

Summary

GL’s LTE Analyser provides Protocol Analysis with capable of capturing and decoding various interfaces i.e. S1, S3, S4, S5 (or S8), S6a, S10, S11, S13 and X2interfaces of the LTE network.
