1. A system-on-chip comprising:

  • a first radio module having a periodic listening mode for asynchronous communication, each cycle of the periodic listening mode having time slots that are each configurable as an active time slot effective to enable asynchronous communication or an inactive time slot effective to prevent asynchronous communication, the time slots of the periodic listening mode being configurable as a duty cycle of consecutive active time slots and consecutive inactive time slots, the first radio module having exclusive access to an antenna during the active time slots and having non-exclusive access to the antenna during the inactive time slots;

    a second radio module configured to communicate via the antenna when the first radio module does not have exclusive access; and

    a communication manager configured to;

    determine that an estimated bandwidth requirement of the first radio module as a percentage of total available antenna access during one cycle of the periodic listening mode is approximately twenty-five percent of a bandwidth available over the antenna,set parameters of the consecutive active time slots and consecutive inactive time slots based on the determined percentage of total available antenna access during one cycle of the periodic listening mode required by the first radio module being approximately twenty-five percent of a bandwidth available over the antenna effective to establish the duty cycle of the periodic listening mode,configure at least two consecutive time slots of the periodic listening mode as inactive time slots effective to prevent the first radio module from having exclusive access to the antenna for at least the two consecutive time slots of the periodic listening mode, andgrant the second radio module access to the antenna for at least a portion of the two consecutive time slots for which the first radio module does not have exclusive access to the antenna.
