User Perspective - Adaptive Frequency Hopping
In the Bluetooth spec 1.1, the Bluetooth devices hop in the 2.4 GHz band over 79-channels. As WLAN
802.11 has become popular, there are improvements in the Bluetooth spec 1.2 specifying how Bluetooth
units can avoid jammed bands and provide an improved co-existence with WLAN.

Technical perspective - Adaptive Frequency Hopping
Figure 4. AFH
First the Master and/or the Slaves identify the jammed channels. The Master decides on the channel dis-
tribution and informs the involved slaves. The Master and the Slaves, at a predefined instant, switch to the
new channel distribution scheme.
No longer jammed channels are re-inserted into the channel distribution scheme. AFH uses the same hop
frequency for transmission as for reception.

User Perspective - Faster Connection
This feature gives the User about 65% faster connection on average when enabled compared to Bluetooth
spec 1.1 connection procedure.
