Abstract
A distributed antenna system comprises a base antenna system and coverage antenna systems. The base antenna system wirelessly receives a network pilot signal and transfers the network pilot signal to a first coverage antenna system and to a second coverage antenna system. The first coverage antenna system wirelessly transfers the network pilot signal and a first pseudo-pilot signal that is correlated to a first location. The second coverage antenna system wirelessly transfers the network pilot signal and a second pseudo-pilot signal that is correlated to a second location. In some examples, user devices translate the pseudo-pilot signals into their correlated locations.
