My first thought was that wireless is probably about all forms of wireless technology, including wifi, bluetooth, proprietary wireless USB devices, etc, but the tag wikis seems to suggest the tags may actually be duplicates, in which case I suggest they ought to be merged:
Examining the 50 most recent wireless questions, all were about wifi. Braiam previously fixed one that was also tagged Bluetooth (one out of all 317 tagged wireless).
So wireless is overwhelmingly about wifi.
Indeed, that's how people use the term. If someone worries about using too much data on their phone plan because his/her smartphone isn't on wireless at work, that makes perfect sense. Wireless means WiFi. You don't become confused because cell data is wireless. Similarly, if someone suggests turning wireless off on your phone to troubleshoot something, you don't put in in airplane mode.
So just merge it all to wifi, and put a synonym in place. The synonym will help people asking questions, and also anyone trying to search by tag.
If at some point people start using wireless to mean AM radio again, a mod can undo the synonym.
Since wireless can be loosely interpreted as anything that transmit data using non-wired medium (RF, wifi, et al) I suggest just renaming wireless to wifi and done. No synonym. Of course it will be helpful to have a list of the questions that were affected so we can review calmly.
- merge wireless into wifi.
- remove any synonymization that puts wireless and wifi to mean the same
This will be in line with our stances of creating technically correct tags without ambiguous meanings, ane synonymizing a ambiguous tag (wireless) with a clear tag (wifi) is not the way to go.
After the discussion in chat, my suggestion is that we:
- Merge all existing wireless questions into wifi
In the future, perhaps other wireless technologies (Wireless USB?) will be ubiquitous enough to warrant their own tag suggestion as well.
