Abstract
A wireless network device comprises a first wireless communication device that includes a first radio frequency (RF) transceiver that generates a synchronization pulse and that transmits and receives data according to a first period. A second wireless communication device receives a signal indicative of the synchronization pulse and includes a second RF transceiver that transmits and receives data according to a second period. The second period is not equal to the first period and the second wireless communication device adjusts the second period according to the first period and the synchronization pulse.
Claims16
A Bluetooth device, comprising:
- a radio frequency transceiver configured to operate in a Bluetooth network, the radio frequency transceiver configured to communicate, with a first network of client stations in the Bluetooth network, according to a first period that is defined by a synchronization signal, wherein the synchronization signal is transmitted prior to a start of data transmission in the Bluetooth network;
- and
- an access point configured to operate in a wireless local area network, the access point configured to receive the synchronization signal,
- determine a second period that is based in part on the first period, and communicate with a second network of client stations according to the second period;
- wherein the access point is configured to adjust communication timing of the second network of client stations based on a multiple of a length of a single time slot of the first period.
A method of operating a Bluetooth device, the method comprising:
- using a radio frequency transceiver configured to operate in a Bluetooth network,
- communicating, with a first network of client stations in the Bluetooth network, according to a first period that is defined by a synchronization signal,
- wherein the synchronization signal is transmitted prior to a start of data transmission in the Bluetooth network;
- and
- using an access point configured to operate in a wireless local area network,
- receiving the synchronization signal,
- determining a second period that is based in part on the first period, and
- communicating with a second network of client stations according to the second period;
- wherein the access point is configured to adjust communication timing of the second network of client stations based on a multiple of a length of a single time slot of the first period.
