Introduction:

As wireless communication and multimedia applications are increasing at a rapid pace and there is need to meet the requirements a better standard for communication is developed titled LTE. With the release of various versions over the years shows a continuous enhancement in the framework standard. This paper discusses about the advent of LTE into the mobile and wireless communication universer and the need for it. The various features and technical aspects are also discussed. With features such as closed subscriber group, self-organising networks, location services, enhancement cell ID and Multimedia Broadcast services this is a standard which pretty much became the norm. Technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output(MIMO) which were instrumental in the evolution to the LTE-Advanced are also discussed.

scalable multiple transmission bandwidths are supported by LTE including one for the packet-switching (PS) mode. Whereby, all traffic flows are provided in the PS domain . The data rate is 100 Mbps in the DL and 50 Mbps in the UL. The throughput and spectrum efficiency are a big improvement from regular HSDPA and USUPA. The average cell spectral efficiency is similar to capacity and the cell edge user throughput is 5% of the CDF of user throughput and both are really important. to mitigate the performance between the vicinity of the cell site and cell edge the throughput plays a big part along with latency reduction. One is the control plane latency, i.e. connection setup latency, the other one is the user plane latency
i.e. transfer delay in RAN. achieved by the specified radio interface achieved the requirements and targets. the inherent robust...

The 3GPP LTE defines the basic functionality of a new, high-performance air interface providing high user data rates in combination with low latency.

Conclsoin :

We have noticed how the LTE came about and later it got evolved into LTE – Advanced. These both offer very high speed access to the internet allowing for easy working of various applications involving voice calls, video calls, etc. The main reason for this evolution are the increased data rates, spectrum efficiency and coverage, reduced latency. Various features of the LTE are also studied and their usefulness. We also studied the secrity features and the various vulnerabilities in the 4G LTE networks. In essence LTE basically set into motion the increased usage of mobile and wireless communications in modern day-to-day activities but there is still space for improvement.
