I don't think this is something that should go into the osm db for the 
same reasons we don't want e.g. air pollution:

  - it can change within days
  - it's not fixed on the ground
  - it's not easy verifiable by a mapper
  - it's different for different people (4st floor vs. basement)

This is sth. that should be saved in a special DB. Maybe one could save 
Points with known quality and calculate Areas around it, estimating the 
quality in other points.

What yould go into OSM are the transmitter stations and their power.
