Abstract
Briefly, in accordance with one or more embodiments, the location of a mobile device within a floor plan of a building or the like environment may be determined using a single transmission link between transceiver and the mobile device. A bit error rate value and a receiver signal strength indication value are measured for the present location of the mobile device in the floor plan. The coordinates where the mobile device is located may be determined by looking up the measured bit error rate value and the received signal strength indication value in a lookup table. Due to environmental factors of the floor plan, the combination of the bit error rate value and the received signal strength indication value corresponds to a unique coordinate location in the floor plan from which the location of the mobile device may be determined.
