Since initial developments in the 1990s using 2.4 GHz spectrum, WiFi has evolved to become a ubiquitous part of electronic communications. Each step along the way has required identification of new radio frequencies capable of being operated in a licence exempt mode and setting the regulatory conditions for use of these. While in the early days there was a high level of commonality, now with use of the 5 GHz and 6 GHz bands there are regional variations in the spectrum available, permissible power levels, technology solutions required to reduce interference risk and enable operation and other restrictions that might be applied. These developments impose both complexity and cost for current and future WiFi developments. In this presentation a brief history of the spectrum and regulatory environment for WiFi is covered together with current work on frequency bands and permissible use.
