Evolution of massive MIMO

NEWS


Massive MIMO (multiple-input and multiple-output) is a well-known technology that has been developed and deployed to cope with the expected high data traffic demand, leveraging existing cell sites (where possible) and the large bandwidths allocated to 5G in c-band and mmWave. In spite of all the advantages that the technology brings for Mobile Network Operators (MNOs), such as enhanced spectral efficiency and better end user data throughputs, there are technical challenges that have driven further investment in Research and Development (R&D) in order to improve the performance of the solution along with innovation in physical features that lead to ease the cell site installation. ABI Research summarizes some of the technical challenges as follows:

  • Pilot Contamination occurs if the same set of orthogonal pilots are used by different User Equipment (UE) in both the neighbor and home cells. The ...
