LTE Analysis and Simulation


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.

LTE Network Test Solutions

  • 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 Protocol Simulation

  • Supports emulation of for several interfaces – currently S1 – MME, eGTP-c ( S3, S4, S5, S8, S10, S11 and S16), and Diameter (S6a, S6d, S13, Cx, Dx, Gx, and Rx), X2-AP interfaces.
  • Simulate up to 500 Smartphones (UEs) powering up and down
  • It can simulate various nodes across LTE network –
    • S1-MME interface - eNodeB (also called Evolved NodeB), and MME (Mobility Management Entity) nodes in
    • eGTP-c interfaces - MME (Mobility Management Entity), SGSN (Serving GPRS Support Node), SGW (Serving Gateway), and PGW (Packet Data Network Gateway)
    • X2-AP interface – two eNodeB (also called Evolved NodeB) end-points
    • Diameter interfaces - MME (Mobility Management Entity), HSS (Home Subscriber Server), AF (Application Function), PCRF (Policy and Charging Rules Function), CSCF (Call Session Control Function), SGSN (Serving GPRS Support Node), PCEF (Policy and Charging Enforcement Function), EIR (Equipment Identity Register) and PDN GW (Packet Data Network Gateway)
  • Authenticate and confirm security procedures
  • QoS requests for greater or lesser bandwidth
  • Temporary addressing management for mobility and security
