Wireless personal area networks with frequency hopping and rotation of the
frequency hopping sequences. In one embodiment, a method of wireless
communication is provided, the method including: transmitting a beacon
frame by a piconet coordinator that specifies a rotation index and
hopping index; receiving a beacon frame by a device associated with or to
be associated with the piconet coordinator; extracting the rotation index
and hopping index by the MAC of the recipient device and communicating
them to the PHY for transmission and reception in a current superframe;
missing a subsequent beacon frame by a recipient device; and using the
rotation index and hopping index previously received to determine a
current frequency hopping sequence for a current superframe following the
missed beacon frame.
