Communication Between Devices using mmWave within Small Cells in Wireless Network and Exploiting Spatial Reuse.

Abstract

In this era of technical evolution, large scale demand and use of wireless mobile communication is drawing attention of academics researchers as well as the industries. The exponential growth of mobile data network traffic, here 4g plays an important role. 60GHz radio frequencies, up to 7GHz bandwidth are allocated worldwide for license free. With the help of unlicensed frequency bandwidth of mmWave of 60Mhz band, many gigabites per second can be transmitted. Communication can be done between the nodes with the spectrums of mirco frequencies available in plenty which provided cost effective communication with high capacity backhaul. Wireless backhaul is one of the emerging options for small cells as it provides a less expensive and easy-to-deploy over fiber cables. There are multitude of bands (e.g. spatial multiplexing, LOS/NLOS etc.) that need to be smartly used to connect to the small cell for communication. Candidate bands include: sub-6 GHz band that is useful in non-line-of-sight (NLOS) scenarios, microwave band (642 GHz) that are used in point-to-point line-of-sight (LOS) scenarios, and mmWave bands (e.g. 60, 70 and 80 GHz) that are mostly being commercially used in LOS scenarios. In many deployment topologies, it is more profitable to use aggregator nodes, located at the roof tops of tall buildings near small cells. This paper proposes, development of new protocol for communication between devices. The protocol provisions concurrent transmission in minimum frequency to the greater extent. Further to enhance the efficiency of network, performance analysis and different parameters will be calculated.
