Channel bonding is primarily used with 5GHz (IEEE* 802.11a) systems as it is the best solution for increased bandwidth with reduced possibility of interference.

The possible channels for 5GHz systems are: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 149, 153, 157 and 161. (Channels may be slightly different depending on the regulatory requirements of the country.)

When selecting the two channels, the primary or control channel is selected first. The secondary or extension channel is selected in relation to the primary channel.

For example if the primary channel is 36 and the secondary channel is 40 the notation would be (36,1). And if the primary channel is 44 and the secondary channel is 40 the notation would be (44,-1). The primary and secondary channels are always next to one another. It is impossible to have a primary channel of 36 and a secondary channel of 56.

Supported combinations of 802.11n channels at 5GHz with 40MHz bandwidth are:
(36,1) (40,-1); (44,1) (48,-1); (52,1) (56,-1); (60,1) (64,-1); (100,1) (104,-1); (108,1) (112,-1); (116,1) (120,-1); (124,1) (128,-1); (132,1) (136,-1); (149,1) (153,-1); (157,1) (161,-1)
