The Wireless Broadband Alliance (WBA) has published the results of the second phase of trials for the low-power IoT-focused WiFi variant – IEEE 802.11ah, i.e. HaLow. As HaLow gears up for commercial adoption, poised to take advantage of the already installed WiFi footprint, these test results should do much to persuade skeptics of the technology. HaLow is most different from the main WiFi flavors because of its support for sub-GHz spectrum. This is the main reason behind its performance, but a number of additional improvements have been made to the standard, to eke more out of the specification. These include narrower channel widths, for better density, and altering the stack to better suit battery-constrained devices. The commercial model should see…
