I’m going to be a little pedantic, for the sake of completeness, because I very much appreciate and value what Decronym bit did here and want it to cover any gaps that may arise (especially for newcomers).
AP doesn’t necessarily have to be wifi or wireless; I’ve used many hardwired APs. WAP stands for wireless access point, though it’s almost always shorthanded to AP (more so now, maybe, because of a dumbass song with the same name).
$15/TB (I’m assuming USD) is incredible!
