Expectations and spectacular developments in the field of mobile communications have paved the way to long Term evolution (lte). Take a look at the changed architecture and the scope of richer content messaging through the evolved 4g technology

With the user and operator requirements and expectations continuing to evolve, the foundation of higher-level open systems interconnect (OSI) model protocols such as Long Term Evolution (LTE) has been incorporated under the third-generation partnership project (3GPP R7).

It is generally assumed that there will be a convergence towards the use of Internet protocols, and all future services will be carried on top of IP. Therefore the focus of the evolution is on enhancements to the packetswitched domain.

Later, with all the inherent drawbacks and discrepancies, the long-term evolution has allowed a smooth migration to a higher-level technology called 4G.

What’s 4G mobile technology?

4G mobile is based on open wireless architecture ( OWA)— a high- speed wireless transmission platform with more cost- effective and spectrumeffective methods.
