A method is provided for a remote device to monitor and communicate with a wireless network using cyclic beacons. The remote device receives a beacon, which beacon includes beacon information that defines a superframe. From the beacon information, the remote device determines whether the received beacon and the associated superframe are assigned to a network device or are unassigned. By receiving as many beacons as there are allowable devices in the network, the remote device can determine if the network is full. If the remote device runs through all of the beacons and all indicate that their associated superframes are assigned, then the remote device determines that the network is full and performs a network-full function. If the remote device receives a beacon that indicates that its associated superframe is unassigned, it determines that the network is not full and performs an association request during the unassigned superframe.
