  I think you've got a conceptual problem here.  (Low-power) 2.4 GHz
equipment is portable, not mobile.  It works by sitting the unit on some
furniture and aiming receiver at transmitter and vice versa.

  You may not have to aim too accurately, but it is not the sort of
thing you walk around with.  Even less so if it's one-way because you
depend on acknowledgements and retransmission ("packet" protocols) to
get the data through if the link is anything other than fixed.
