Abstract
A wireless communication device determines its location and communicates the location to other local devices utilizing a nonstandard, standard and/or proprietary protocol in combination with another protocol such as a Bluetooth, RFID, IEEE 802.11 and/or a cellular phone protocol. The location may be determined utilizing a GNSS receiver and/or network device information. A new location may be determined based on the determined location, a relative distance and/or a relative direction to other local devices. Determined location information may be communicated to other devices via a network. The wireless communication device may receive locations and/or corresponding location uncertainties from devices located within a limited range. The received information is utilized to determine a more accurate location. The more accurate location is communicated back to the devices within the limited range and/or to other communication devices.
