ABSTRACT:
A computing arrangement may include a first radio transceiver operating in accordance with a first communication protocol using a frequency band and a second radio transceiver operating in accordance with a second communication protocol using the frequency band. An access point operates in accordance with the first communication protocol and transmits a communication signal that has a frame including a first time interval indicative of when communications using the first communication protocol via the frequency band are permitted to the computing arrangement. The computing arrangement determines if the frame includes a second time interval, which is indicative of and is reserved for exclusive communications in accordance with the second communication protocol. If the second time interval is absent from the frame, the computing arrangement inserts the second time interval into the frame. The computing arrangement communicates with a further device only during the second time interval.
