4G is the integration of wireless LAN and Wide Area Network providing 100MHz for mobile and 1GHz for stationary devices. It uses packet switching networking and is based on Orthogonal Frequency Division Multiplexing Access (OFDMA) technology. Wireless LANs soon will begin multiplying or more in throughput and range if a smart antenna technology named MIMO works out as its benefactors foresee. The Third Generation Partnership Project (3GPP) Evolved Universal Terrestial Radio Access (E-UTRA) Long Term Evolution (LTE) principles are a piece of 3G advancements. Multi-input,multi –output (MIMO) has turned into a key innovation to enhance communication over a wireless channel. With constrained spectrum, MIMO procedures attain to least target cell spectral proficiency, peak spectral effectiveness and cell edge client spectral efficiency which are the base necessities indicated by the ITU. 4G allows IP-based voice, information and streaming multimedia at higher speeds and offers no less than 100 Mbit/s with high versatility and up to 1GBit/s with low portability (traveling). Various advancements thought to be 4G measures incorporate Long Term Evolution (LTE), Ultra Mobile Broadband (UMB) and the IEEE 802.16 (WiMax) standard. At the point when utilized as a part of MIMO frameworks it would have the capacity to give high information rate up to 100Mbps furthermore give QoS and Security administrations to end clients. The 4G goal is to meet difficulties displayed by the perpetually
