Overview
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.
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.

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.
End-to-End Voice, Data and Video Quality Measurement Systems for all NextGen Networks
(LTE 4G, GSM, and UMTS Smartphones)
- Connect to Mobile Phones, Smart Phones, and Broadband Devices using GL’s portable VQuad™ -
Dual UTA system.
- Test LTE devices for Voice, Data, Video quality metrics with complete automation and centrally controlled system
- Use GL’s VQuad™ - Dual UTA to confirm quality of service during the network upgrade process
- VQuad™ can send commands to the Mobile Device Controller application residing on the smart phones to remotely perform
Automated Data Testing irrespective of whether the phone is on a voice call or not.
LTE Analysis and Simulation
- LTE analyzer is capable of capturing, decoding and performing various test measurements between any two nodes across various interfaces
including S1, S3, S4, S5 (or S8), S6a, S10, S11, S13 and X2 interfaces of the LTE network
- GL has released LTE Protocol Simulation for several interfaces – currently S1 – MME, and eGTP (S5/S8 and S11).
- Simulate up to 500 Smartphones (UEs) powering up and down
- It can simulate eNodeB (also called Evolved NodeB), and MME (Mobility Management Entity) and other interfaces
- Authenticate and confirm security procedures
- Supports both Real-time and Offline types of LTE Analyzer
- QoS requests for greater or lesser bandwidth
- Temporary addressing management for mobility and security
- Trace files for analysis can be loaded through simple command-line arguments.
