Abstract
A system and method for preventing a wireless controller system and WiFi radio system within a game console from interfering with each other. Specifically, the WiFi system is adapted to avoid activating its transmitter during the controller receive times by detecting a signal sent to the WiFi module indicating where the controller receive times occur without an explicit signal indicative of the controller receive times.
Claims17
A gaming console, comprising:
- a memory;
- a microprocessor;
- an RF energy detection module;
- a first radio subsystem that communicates to a network infrastructure;
- and
- a second radio subsystem that communicates to a wireless accessory,
- wherein when said second radio subsystem communicates to said wireless accessory, said RF energy detection module receives transmissions from said second radio subsystem and generates a signal that is input to a local timing signal in order to delay and output of said first radio subsystem such that the transmissions from the first radio subsystem do not interfere with said second radio subsystem.
A method of collaboration between a first radio subsystem and a second radio subsystem in a gaming console, comprising:
- generating a local timing signal provided to said first radio subsystem;
- detecting transmissions of said second radio subsystem;
- adjusting said local timing signal in accordance with said detected transmissions;
- and
- delaying and output of said first radio subsystem such that the transmissions from the first radio subsystem do not interfere with said second radio subsystem.
A method of collaboration between a WiFi radio and an Adaptive Frequency Hopping (AFH) radio that share frequency spectrum, comprising:
- generating a local timing signal provided to said WiFi radio;
- detecting transmissions of said AFH radio;
- adjusting said local timing signal in accordance with said detected transmissions;
- and
- delaying and output of said WiFi radio such that the transmissions from said WiFi radio do not interfere with said AFH radio.
