Abstract
A gaming table includes a network analyzer. The network analyzer detects antenna reflection coefficients faster than RFID tags can be read, enabling game state information to be monitored quickly. The network analyzer detects changes in the reflection coefficients that result from movements of a human appendage, enabling the system to change game states in response to the detected hand movements.
