Abstract :
This paper introduces a novel 128-element sub-6 GHz Massive MIMO (Multiple-Input Multiple-Output) testbed being developed by the University of Bristol in collaboration with National Instruments and Lund University as part of the BIO (Bristol is Open) city testbed. Distributed Massive MIMO systems avoid large single-piece antenna facets and their associated windage problems and also offer greater spatial diversity, but node synchronization and phase alignment becomes more challenging. Simulated network performance of a co-located 128-element 3D Multi-User MIMO system at a possible test site in Bristol are presented based on our 3D channel propagation model.
