Abstract
A system for accurate positioning of a communication devices includes a plurality of positioning cells configured for synchronizing to the cellular network and to each other, and for emitting positioning signals during time intervals proximal to time points at which the cellular network emits synchronization signals. In the manner, the positioning signals reach the communication device when the communication device's antenna is on for listening to a synchronization signal of the cellular network. Processing the times of arrival of the positioning signals by a server in communication with the communication device enables accurate positioning of the communication device.
