A plurality of beacons transmit beacon signals indicating beacon identifiers. A mobile communication device receives a first one of the beacon signals indicating a first one of the beacon identifiers when the mobile communication device is proximate to a first one of the beacons. The mobile communication device generates a random code and transmits a first message indicating the first beacon identifier and the random code. The mobile communication device receives a second one of the beacon signals indicating a second one of the beacon identifiers when the mobile communication device is proximate to a second one of the beacons and transmits a second message indicating the second beacon identifier and the random code. A computer system receives the first message and the second message and processes the random code, the first beacon identifier, and the second beacon identifier to determine the velocity of the mobile communication device.
