We’re all used to wireless networking, but if there’s one thing the ubiquitous WiFi on 2.4 or 5 GHz lacks, it’s range. Inside buildings, it will be stopped in its tracks by anything more than a mediocre wall, and outside, it can be difficult to connect at any useful rate more than a few tens of metres away without resorting to directional antennas and hope. Technologies such as LoRa provide a much longer range at the expense of minuscule bandwidth, but beyond that, there has been little joy. As [Andreas Spiess] points out in a recent video though, this is about to change, as devices using the so-called HaLow or IEEE 802.11ah protocol are starting to edge into the realm of affordability.
