A Comprehensive Research Study on 5G Backhauling: Solutions, Requirements and Challenges

Abstract

The 5 th generation cellular technology i.e. 5G network is considered as most emerging wireless technology to enable the IoTs. Nevertheless, the key challenge is to offer a ubiquitous and efficient backhaul networking to small cell devices. There are several backhaul solutions are available which can address the backhaul challenges for 5G networks. In this context, the present survey study providing a detail overview on 5G infrastructure with respect to different architectural concept followed by different backhaul solutions. A qualitative review on prior backhaul solutions and different standards are discussed. Furthermore, highlighting perceives solutions over 5G backhaul networks, which are not apparent when backhaul networking is examined as individual part of 5G technology. This comprehensive survey study is key in exploring the significant catalysts which are supposed to mutually cover the way to solve the new wireless backhaul challenge. In the last, have defined key points generated from existing solution and providing consolidated research directions for new 5G backhaul network deployment.
