Massive MIMO goes Sub-GHz: Implementation and Experimental Exploration for LPWANs
Massive MIMO goes Sub-GHz: Implementation and Experimental Exploration for LPWANs
Low-Power Wide-Area Networks operating in the unlicensed bands are being deployed to connect a rapidly growing number of Internet-of-Things devices. While the unlicensed sub-GHz band offers favorable propagation for long-range connections, measurements show that the energy consumption of the nodes is still mostly dominated by the wireless transmission affecting their …
