Abstract: A system and a method are disclosed for protecting the privacy of a wireless data transmission. A request is received from a client device to connect to a base station. A session identification is assigned to the client device and a set of transmission identifications are generated using a block cipher with the assigned session identification and a secret key as input. The transmission identifications identify a frequency channel and a time slot for the client device to wirelessly transmit a message to the base station. The set of transmission identifications are then encrypted and sent to the client device.

Abstract: A system and a method are disclosed for transmitting and receiving wireless signals in a shared communication channel. Embodiments include sending, by a client device, a request to connect with a base station and receiving, in response to the request, a message including a radio transmission slot and a digital identifier. The radio transmission slot identifies a frequency channel and a time slot for transmitting a wireless signal. The client device can then transmit wireless signals using the frequency channel identified by the radio transmission slot during the time slot identified by the radio transmission slot. The client device encodes the digital identifier in the transmitted wireless signal.
