The 5G era has brought more deployments, booming data traffic and subscriber growth. Networks require new levels of spectral efficiency to meet the user and capacity demands now required. Mid-band is the sweet spot between coverage and capacity: Massive MIMO technology offers communications service providers the larger bandwidth of the mid-band to deliver powerful 5G experiences in a cost and energy efficient way.
Massive MIMO explained
Massive MIMO more effectively exploits the spatial domain to improve the coverage, capacity and user throughput of mobile networks. This is achieved by harnessing multi-antenna technologies like beamforming, null forming and multiplexing. The results include a better user experience, higher network capacity, and an ability to support long-term traffic growth that would not be possible with conventional solutions using remote radio units.
Traditional MIMO (LTE, Wi-Fi)
Multi-antenna technologies have existed for several decades, and by the time of the 4G/LTE era were being deployed in a range of commercial uses, with techniques even used in everyday Wi-Fi routers.
Multiple input multiple output (MIMO) systems use multiple antennas at both the transmitter and receiver along with software to coordinate signal paths and ultimately increase throughput. The resulting gains were a significant breakthrough, but the 5G era demands far more in terms of throughput and capacity. Enter, Massive MIMO.
The evolution to Massive MIMO
Massive MIMO dramatically expands upon the scale and capabilities of MIMO, and has been an intrinsic component of networks since the start of 5G.
