For ultimate future proofing run conduit from accessible areas to the back of wall panels (and to bridge between roof spaces etc). Sounds like future wifi standards may require an access point mounted on the ceiling of every room too...

 

Im sure we can all remember when "futurepoofing" for computer's was running a phone line to every bedroom (cos in the future there is going to be a computer in every room that, but we will access the internet via dial up one computer at a time).

 

Who knows what the dominant standard will be in 20 years time.
