Abstract
Various techniques are disclosed for facilitating tracking locations of players and/or wireless communication devices in a casino network. In at least one embodiment, an electronically switched Doppler antenna array may be utilized to detect a first wireless signal from a first signal source. Bearing information may be generated using information from the detected signal. In at least one embodiment, the bearing information may include a first directional bearing to the first signal source. Using at least a portion of the first bearing information, a first location of the first signal source may be determined. According to specific embodiments, the first signal source may correspond to a wireless communication device such as an RFID-enabled player tracking card or gaming chip. In at least one embodiment, a current location of the wireless communication device may be automatically tracked in real-time as the wireless communication device is moved through a first region of the casino.
