Massive MIMO for future wireless networks: about scalability and sustainability

Future wireless networks should support a very large number of simultaneous high throughput streams. Moreover, sustainable connectivity for IoT nodes operating on an ultra-constrained energy budget is desired.

We will present recent results and experiments that confirm that distributed massive MIMO operating in the ‘golden’ below 6GHz frequencies can offer both scalability and sustainability.

Furthermore, the use of new waveforms, the design of initial access protocols, (non-full) coherent operation, and synchronization in cell-free networks offer both technological challenges and compelling opportunities to grasp.
