1. A system for indoor localization using satellite navigation signals in a Distributed Antenna System, the system comprising:
a plurality of Off-Air Access Units (OAAUs), each of the plurality of OAAUs operable to receive an individual satellite navigation signal from at least one of a plurality of satellites and operable to route signals optically to one or more DAUs; a plurality of remote DRUs located at a Remote location, wherein the plurality of remote DRUs are operable to receive signals from a plurality of the one or more DAUs; and an algorithm to delay each individual satellite navigation signal for providing indoor localization at each of the plurality of DRUs. |
