NS3 LTE Simulation is also the latest high-speed cellular transmission network.LTE is a 4G technology also with download speeds that run the gamut from 3 to 28 Mbps worldwide.4G LTE is also one of several competing 4G standards along with Ultra Mobile Broadband (UMB) andWiMax (IEEE 802.16).Ns3 is also the best choice among network simulator for simulating LTE framework.We also provide customize NS3 LTE Simulation Projects based on customer Requirements.
Advantages of LTE:
- LTE will supports seamless connection also to existing networks like GSM,CDMA and WCDMA.
- It has also simple architecture because of low operating expenditure
- Time required also for connecting network and is in range of a few hundred ms and power savings states can now enter and exited very quickly
- High data rates can be achieved also in both downlink as well as uplink.
- Both FDD and TDD can also used on same platform.
- Optimized signaling for connection establishment and also other air interface and mobility management procedures have further improved the user experience.
Architecture of NS3 LTE Simulation:
LTE parameters:
- Transmission bandwidth.
- Mobility.
- Frequency range.
- Duplexing.
- Channel bandwidth.
- Channel coding.
- MIMO.
- Multi-antenna technology.
Sample code for LTE:
