NS3 LTE Simulation

LTE is the latest high-speed cellular transmission network.LTE is a 4G technology with download speeds that run the gamut from 3 to 28 Mbps worldwide.4G LTE is one of several competing 4G standards along with Ultra Mobile Broadband (UMB) andWiMax (IEEE 802.16).Ns3 is the best choice among network simulator for simulating LTE framework.We provide customized NS3 LTE Simulation Projects based on customer Requirements.

Advantages of LTE:

  • LTE will supports seamless connection to existing networks like GSM,CDMA and WCDMA.
  • It has simple architecture because of low operating expenditure
  • Time required for connecting network and is in range of a few hundred ms and power savings states can now be entered and exited very quickly
  • High data rates can be achieved in both downlink as well as uplink.
  • Both FDD and TDD can be used on same platform.
  • Optimized signaling for connection establishment and other air interface and mobility management procedures have further improved the user experience.

Architecture of LTE:


LTE parameters:

  • Transmission bandwidth.
  • Mobility.
  • Frequency range.
  • Duplexing.
  • Channel bandwidth.
  • Channel coding.
  • MIMO.
  • Multi-antenna technology.
