Due to limited bandwidth in 2.4 GHz ISM band, only three non-overlapping 20 MHz channels (1, 6, and 11) are feasible in most regulatory domains. This allows deployment of multiple APs and facilitates frequency reuse. With 40 MHz channel width, only one AP can be deployed. Further, interference/contention with neighboring WLANs is more likely due to increased coverage. Hence, 40 MHz operation in the 2.4 GHz band should be avoided.
