5G Massive MIMO

Massive MIMO extends conventional MIMO antenna technology used today. MIMO typically uses two transmit and two receive antenna elements to run two parallel streams of data between the base station and device, doubling the capacity. Massive MIMO goes further, using many simultaneous transmit and receive streams controlled by advanced software to create much higher network capacity.

AirScale massive MIMO Adaptive Antenna deploys 64 transmit and 64 receive streams to deliver up to five times more network capacity and wider coverage. Massive MIMO also enhances beamforming. 3D, or Full Dimension (FD), beamforming increases hotspot capacity and improves indoor penetration, while also providing extended coverage. All of which means operators can avoid the need for network densification involving the costly building of new base station sites.
In future 5G deployments, massive MIMO will enable new high frequency bands that typically suffer high propagation path losses to deliver similar coverage as lower frequencies. Once again the need to build many more new sites will be reduced.

AirScale Base Stations are 5G ready, deliver Single RAN for FDD and TDD, offer market-leading 28 Gbps throughput per system module, which handles baseband and control, and includes fronthaul and backhaul interfaces. More baseband capacity can be implemented by simply chaining together more system modules. Furthermore, AirScale Base Station can take advantage of additional baseband capacity available from AirScale Cloud RAN for unlimited scalability.
