Using "channel bonding" the 802.11n wireless standard is capable of operating on two separate channels at the same time. This feature allows 802.11n networks to double their bandwidth, however it can result in increases interference and power usage.
IEEE 802.11n-2009, commonly shortened to 802.11n, is a wireless-networking standard that uses multiple antennas to increase data rates. The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4. It standardized support for multiple-input multiple-output, frame aggregation, and security improvements, among other features, and can be used in the 2.4 GHz or 5 GHz frequency bands.
As the first Wi-Fi standard that introduced MIMO (Multiple-Input and Multiple-Output) support, sometimes devices/systems that support 802.11n …
