  • System and method for increasing the range or bandwidth of a wireless digital communication network
    Patent number: 7606222
    Abstract: A system and method, associated with a receiver, for increasing the range or bandwidth of a wireless digital communication network and a receiver incorporating the system or the method. In one embodiment, the system includes: (1) a service class detector configured to determine a service class of a PDU received by the receiver from the wireless digital communication network and (2) a frame check sequence checker coupled to the service class detector and configured to disregard error-checking information in the PDU when the service class indicates that the PDU is a streaming media PDU.
    Type: Grant

  • Interoperability and coexistence between two disparate communication systems
    Publication number: 20040242159
    Abstract: Combined IEEE 802.11 (WiFi) and Bluetooth transceiver and method of operation employing busy signals to monitor when transmissions of each type are being transmitted or received, and employing a synchronizing signal to synchronize the use of time slots. In one embodiment, a simple two-wire interface is exposed linking Bluetooth and IEEE 802.11 radio systems. In another embodiment, the Bluetooth and IEEE 802.11 services can exchange information including scheduling, mode of operation, channel usage and device state via a shared resource such as a memory, referred to as a ‘mailbox’.
