WebThe frequency hopping spread spectrum variant of 802.11 includes information about how long each station is expected to remain in each beacon frame.Are wired and wireless Bluetooth beacon frames able to communicate with one another? WebAFH is used in Bluetooth wireless technology to improve resistance to radio frequency interference by circumventing high-traffic frequencies in the hopping sequence. This type of adaptive transmission is simpler to implement with FHSS than with DSSS.
