Detailed explanation-1: -Abstract-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.
Detailed explanation-2: -What was the first 802.11 standard to implement channel bonding? Explanation: Beginning with 802.11n, two adjacent 20-MHz channels can be combined, or bonded, to make a 40-MHz channel.
Detailed explanation-3: -IEEE 802.11n-2009 or 802.11n is a wireless-networking standard that uses multiple antennas to increase data rates.
Detailed explanation-4: -The 802.11n standard support maximum theoretical network bandwidth up to 300 Mbps. The IEEE802. 11n indoor/outdoor ranges are 75m, and 250m respectively.
