I've been working recently with content falling under the heading Radio Frequency. I've noticed the tag wireless is synonymous with wifi. In fact, it defaults to wifi, and this is reasonable considering its proper usage. But as for the wireless, I'd rather not have it a synonym of wifi.
The term wireless in its basic or original meaning denotes a communication technology, which doesn't employ a wire, in general. And what I would do is to make it stand for itself for the wireless communication in general. Moreover, I'd make it synonymous with a yet nonexistent tag rf, denoting Radio Frequency technologies ranging from bluetooth through mobile to satellite.
- wifi is synonymous there with ieee-802.11
while wireless has this usage instruction:
For WiFi or 802.11 questions, please use the [ieee-802.11] tag. For questions about wireless networking, including any licensed or unlicensed RF medium used to provide point-to-point or point-to-multipoint network links.
