Southampton for Wireless Communications is amazing. Southamptons reputation for anything related to computer science is way better than anyone else.
Oxbridge/Imperial would probably be considered the overall strongest compsci departments in the UK at postgraduate/research level, then Manchester/Edinburgh/Southampton/Bristol just below that, and Glasgow slightly lower (check QS/ARWU if you dont believe me).
We are talking about very small differences though, all 4 are very good universities
I dont know anything about Wireless Communications in particular though, its possible one of those universities is especially strong in that area.
