Low-power Wide Area Networks (LPWANs)

LWPANs are a family of emerging technologies that fill the market gap for cost-effective, low-power, long-distance, narrow-band communication. As for LR-WPAN, different industrial alliances have been formed in the attempt to conquer the market, and in some cases, establish a standard protocol stack for universal LPWAN networks. This process has led to a healthy competition on features, costs, and power-saving features.

LPWAN technologies are usually based on sub-GHz physical channels, but using different radio settings, allowing for an increased range. Devices can communicate with each other over the air, and in some cases use an infrastructure to increase coverage, even across thousands of kilometers, ...
