System and method of determining a location based on location of detected signals |
摘要 |
A system and method is provided that allows a client device to determine its position based on the location of signals detected by the device. The signals' locations may be obtained from a server, and some of the information may be pre-fetched and sent to the client device before the client device detect the signals. The pre-fetched data may also be encrypted so that a client device cannot determine the location of a signal unless it is proximate to the signal. |
