Abstract
A digital device 310 with a plurality of collocated wireless networks encounters inter-network interference if the collocated wireless networks operate in a common operating frequency. A coordinator unit 510, coupled to the plurality of wireless networks, provides a transmission reservation system wherein a wireless network with a need to transmit can request and receive a reservation for time to transmit. The coordinator unit 510 provides a way to schedule transmissions from the plurality of wireless networks and to reduce the probability of collisions.

22. A coordinator unit comprising:
-
a reservation request flag line, the reservation request flag line to denote a status of a pending reservation request;
an arbiter unit coupled to the reservation request flag line, the arbiter unit containing circuitry to receive reservation requests and to grant reservation requests based on the state of the reservation request flag line; and
a scheduler unit coupled to the arbiter unit and the reservation request flag line, the scheduler unit containing circuitry to maintain a list of granted reservation requests and to assert the status of a pending reservation request on the reservation request flag line. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
