Abstract:
1. A method of transmitting information in a wireless network to facilitate a determination of a position of a wireless mobile receiver in the wireless network, comprising: determining time offset information, with respect to a common clock, associated with a transmitter for signal transmission between the transmitter and the wireless mobile receiver in the wireless network; controlling a delay time apparent at the wireless mobile receiver for the transmission signal by modifying at least a portion of a waveform of the transmission signal so as to adjust a phase of the portion of the transmission signal based on the determined time offset information; and transmitting the adjusted transmission signal comprising the modified waveform from the transmitter to the wireless mobile receiver to enable a determination of the position of the wireless mobile device, based in part on the delay time perceived by the wireless mobile receiver; wherein the transmission signal includes a positive or negative parameter to indicate an advancing or a delaying of the transmission signal with respect to the common clock that is based on a global positioning system signal.
