Massive MIMO solutions increase capacity and coverage, while also improving energy efficiency
As demand for mobile broadband services explodes, operators need to maximize the efficiency of their valuable spectrum resources to increase network capacity.
Massive Multiple Input Multiple Output (MIMO) techniques and products hold the to achieving this. Today’s MIMO antennas typically use two transmit and two receive antenna elements, which double the capacity of a basic antenna. Developed by Nokia’s Bell Labs, Massive MIMO goes further, using many antenna elements to simultaneous transmit and receive streams of signals controlled by advanced software to create a much higher network capacity.
Nokia’s AirScale massive MIMO Adaptive Antennas are available in a wide variety of configurations, frequency bands and power outputs to fulfil most deployment scenarios. These Massive MIMO antennas leverage beamforming techniques to deliver efficient coverage and improved indoor penetration.
With Massive MIMO, operators now have a powerful new tool to boost capacity using their existing spectrum.
Nokia and Sprint have jointly proven the benefits of Massive MIMO, with Sprint becoming first U.S. operator to demonstrate massive MIMO for TDD-LTE spectrum with 64T64R, for both the downlink and uplink on an existing LTE frequency.
