Evolution to 5G Massive MIMO: Beamforming Simulation

Application Notes

Cellular evolution is accelerating due to the high expectations of 5G. The ever-increasing demand for more data and improved efficiency is driving radio access technology to higher frequency bands, which offers significantly more available bandwidth, and to smaller cells, operating at lower power and allowing network densification.

 

One revolutionary change is in the use of massive multipleinput / multiple-output (MIMO) antenna schemes, enabling spatial multiplexing and maximizing the reuse of scarce bandwidth. With massive MIMO beamforming, it becomes possible to move the network forward from the traditional point-to-multipoint paradigm to a real-time adaptive point-to-point link, with the base station tracking the user and steering its signal to them. Improved antenna gain overcomes path loss, enabling higher data rates per hertz compared with an isotropic signal at the same power.
