Study of Redundancy with Domain Proxy for Citizen Broadband Radio Service in 5G Network

In order to ensure a significant increase in the requirements of the bandwidth and the devices for many applications, the CBRS is suggested as a means. Citizen's Broadband Radio Service (CBRS) is a set of new frequency bands that can be accessed or authorized for the private communication. CBRS provides a new spectral range of 150 MHz that is dearly needed for firms all of which have cluttered wireless network or want more authority over their networks. This paper shows the analysis of how the CBRS communication is done between the CBSDs and SAS without the presence of domain proxy and explains the implementation and design of the domain proxy along with the protocol for the CBRS communication to the domain proxy for the acquisition of spectrum and relinquishment from the CBSD. The paper also presents the proposed system of using the secondary domain proxy to improve the network robustness in case of primary domain proxy failure and introducing the secondary SAS for interoperability for the communication network.
