New hopes for TV white space solutions in IoT and rural wireless

The TV white spaces (TVWS) spectrum was once proclaimed as a resource that would transform the wireless industry, from supporting low cost broadband access to supporting low power IoT networks. In fact, other IoT technologies such as LoRa, in 868/900 MHz spectrum, left the TVWS initiatives behind, and the spectrum has proved too limited in capacity to add significantly to the WiFi landscape. But Microsoft and Google, in particular, have continued to push this source of unlicensed spectrum, in broadband projects in emerging economies, and in the USA. Microsoft set up the AirBand Alliance in 2017 to promote TVWS solutions, mainly for rural fixed wireless, both for consumer broadband and IoT.
