Technical perspective - Extended SCO
eSCO incorporates CRC, negotiable data rate, negotiable retransmission window and multi-slot packets.
Retransmission of lost or corrupted packets during the retransmission window guarantees on-time deliv-
ery.

7.7 V1.2 detailed functionality - Adaptive Frequency Hopping
User Perspective - Adaptive Frequency Hopping
In the Bluetooth spec 1.1 the Bluetooth devices hop in the 2.4 GHz band over 79-channels. Since WLAN
802.11 has become popular, there are specification improvements in the 1.2-SIG spec for Bluetooth
where the Bluetooth units can avoid the jammed bands and thereby provide an improved co-existence
with WLAN.
Technical perspective - Adaptive Frequency Hopping
Figure 6. 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
