The IEEE 802.11n standard defines channel bonding that allows wireless devices to operate on 40MHz channels by doubling their bandwidth from standard 20MHz channels. Increasing channel width increases capacity, but it comes at the cost of decreased transmission range and greater susceptibility to interference. However, with the incorporation of Multiple-Input Multiple-Output (MIMO) technology in 802.11n, devices can now exploit the increased transmission rates from wider channels with minimal sacrifice to signal quality and range. The authors' paper is to identify the network factors that influence the performance of channel bonding in 802.11n networks and make intelligent channel bonding decisions.
