Abstract: Various arrangements for determining a location of a base station without timing synchronization are presented. A mobile device may determine that it is moving faster than a threshold velocity. The mobile device may capture a first unsynchronized time of arrival (TOA) measurement and determine an associated first location, wherein the first unsynchronized TOA measurement is based on a first unsynchronized timing measurement of a first received reference signal. The mobile device may capture a second unsynchronized TOA measurement and determine an associated second location, wherein the second unsynchronized TOA measurement is based on a second unsynchronized timing measurement of a second received reference signal. Based on the mobile device moving faster than the threshold velocity, the first location, the second location, the first unsynchronized TOA measurement, and the second unsynchronized TOA measurement may be used for determining the location of the base station.

Abstract: Disclosed are systems, methods and devices for application of determining position information for mobile devices. In specific implementations, measurement of a signal travel time and a signal's strength may be combined to characterize a transmission power of the signal's transmitter. The characterized transmission power may be applied to affect expected signal strength signature values for use of the signal's transmitter may be updated in order to enhance a location based service where location may be effected by accuracy of a transmitter's power.
