General Overview of 5th Generation Wireless Technology
The 5thgeneration wireless is known as a wireless networking architecture which is built on 802.11 ac Institute of Electrical and Electronics Engineers (IEEE) wireless networking standards. The method has the objective to enhance the data communication speed to at least thrice compared to the 4G technology (IEEE 802.11n). The new technology implements the architecture recommendations by the IEEE 802.11ac and it will operate in the 5 GigaHertz frequency mode. The new technology is composed with the primary objective of availing an increased amount of data communication rate between the wireless local area networks and that will result in an increment of speed up to 1.5 GBps and an area coverage of 90 meters which will be thrice of the 802.1n.

The technological industry is significantly depending on the advantageous factors of the new technology for faster and smoother processing. The paper discusses the implementation of the 5th generation wireless network and the factors which are influential for the implementation of the new technology.
