New network generation needs to cope with demand of high area throughput to manage with the growing wireless data traffic. Previous network generations resulted improvement in area throughput by cell densification and allocation of more bandwidth. Further cell densification is complex and it appears that a saturation point is reached. Valuable frequency bands below 6 GHz provide good network coverage and service quality. Higher bands work well for short range line-of –sight conditions. So we cannot expect major bandwidth improvements. Earlier network generations has not seen any improvements in spectral efficiency (bit/s/Hz/cell). This paper describes the physical layer technology for Massive MIMO to improve the spectral efficiency for future 5G networks.
