Claim:
1. An apparatus, comprising: a memory; a microprocessor; a first radio subsystem that transmits data to and receives data from a network infrastructure; and a second radio subsystem that transmits data to and receives data from a wireless accessory during defined time slots that repeat over time, the first and second radio subsystems operating independently of each other; and a radio frequency (RF) energy detection module that detects wireless transmissions of said second radio subsystem and autonomously generates, based on the detected wireless transmissions of said second radio subsystem, a frame timing signal that reflects the time slots in which data is transmitted and received by the second radio subsystem, the frame timing signal generated by the RF energy detection module being used to control the timing of transmissions by said first radio subsystem to reduce interference between the first and second radio subsystems.
