Wireless personal area networks with rotation of frequency hopping sequences

A method of wireless communication that comprises:

• coordinating a series of superframes, wherein the coordinating includes transmitting a beacon for each superframe,
• wherein each beacon indicates a frequency hopping sequence to be used for communications during that superframe, and
• wherein each beacon specifies a rotation sequence indicative of frequency hopping sequences that will be used for communications in subsequent superframes;
• and
• using the frequency hopping sequence for each superframe to receive any frames other than the beacon during that superframe.

A piconet member device that comprises:

• an antenna;
• a processor coupled to the antenna to receive and transmit piconet communications;
• and
• a memory coupled to the processor, wherein the memory stores software that configure the processor to:
• detect beacon frames in the received piconet communications, wherein the beacon frames delineate piconet superframes;
• and
• obtain from the beacon frames a rotation sequence for frequency hopping sequences.

A piconet coordinator device that comprises:

• an antenna;
• and
• a processor coupled to the antenna to receive and transmit piconet communications, wherein the processor is configured to:
• transmit beacon frames that delineate piconet superframes, wherein each beacon frame includes a field that specifies a rotation sequence for frequency hopping sequences, and further includes a field that indicates a frequency hopping sequence to be used in an associated superframe.
