Abstract
A method includes: receiving, at a mobile device configured for communication using a communication protocol associated with a dedicated frequency band, a first inbound signal from a first node, the first inbound signal having a format in accordance with the communication protocol and having a first frequency that is outside the dedicated frequency band; receiving a second inbound signal, from a second node, having a same format in accordance with the communication protocol as the first inbound signal and having a second frequency in the dedicated frequency band; determining location information for the first node using the first inbound signal; and sending an outbound signal to a location server, the outbound signal including the location information for the first node and a node identifier of the second node, the outbound signal being formatted according to the communication protocol and having a frequency in the dedicated frequency band.
