As in the title, ExtendedAE adds a Requester Terminal, I'd really like to see its Wireless Version

do you mean merequester's Requester Terminal?
to my knowledge, ExtendedAE doesn't add a Requester Terminal.

a wireless requester terminal for merequester has been worked on in the past, however it was put on hold due to time constraints. (see AlmostReliable/merequester#11)
it is likely to be worked on again in the near future, tho there are also some changes to ae2wtlib I want to make which should happen before that
