5. Ease of handover - Seamless mobility across existing 3G  networks to enable world mobility.

6. Better multi path and interference resistance - Use of OFDM and MIMO makers this technology more robust toward multi-path or interference in general.
 
7. Simultaneous user support - Resources can be allocated both in time and frequency. This enables multiple users in a single time slot. 3G only allows 1 user per timeslot.

8. Better encryption and security -  Use of 128 bit encryption keys and AES algorithms.

6. Low cost - lower CAPEX and OPEX cost for network providers with best multimedia experience in return.

What is LTE ? 4G LTE (Long Term Evolution) is a fourth generation standard for broadband mobile technology. This standard is developed to meet long term future requirements of higher data rates, lower latency, better cell coverage and seamless handover.

The lte technology is developed to co-exist with existing 3G networks and allow Network providers to grow services, applications, quality etc.

LTE is purely a packet based switching based on OFDM (Orthogonal frequency division Multiplexing) standard.  

Following are some key driving forces behind LTE.
1. Higher data rates or throughput -

2. Better cell coverage - Improved cellular coverage and better indoor penetration. Target 5 km for with good performance and 30 km with acceptable performance.

3. Low Latency - Latency in 3G networks are around 50-100 ms. The proposal for 4G networks is to reduce the delays by 1/5th.  

4. Higher capacity - High capacity directly relates to better efficiency. The target is to achieve transfer of 15 bits/Hz. 4G networks are expected to be around 3-4 times more efficient
