Abstract
Electronic equipment in a system may transmit and receive wireless advertisement messages. Each wireless message may include location information and may have an associated received signal strength indicator when received from transmitting equipment by receiving equipment. The transmitting equipment may be associated with stationary equipment such as equipment installed at a building, adjacent to a road, or in traffic control equipment or other traffic structures. The receiving electronic equipment may be mobile equipment such as a vehicle or mobile computing equipment such as a cellular telephone or portable computer. Satellite navigation system signals may be received by the receiving electronic equipment in addition to the wireless messages. The receiving electronic information can present alerts to a user based on a location determined using the wireless messages and the satellite navigation system signals.
