The most demanding constraints for next-generation wireless communication systems (5G) are meeting ever-increasing requirement for high data rates while providing a seamless quality of service across the whole network. The deployment of huge Massive Input Massive Output array of antenna and Small cell spatial densification are significant facilitators of high information output, broader scope, as well as increased energy efficiency. However, there are certain critical drawbacks with this technology that must be solved, including performance decrease owing to hardware limitations. To that end, this essay investigates Hardware flaws and their consequences for massive multiple-input multiple-output. In addition, The EE expanding point of operation may be negligible in terms of spectral efficiency, and by increasing the number of base stations, energy may be considerably enhanced.
