Which standard supports channel bonding?
A.
802.11g
B.
802.11n
C.
802.11a
D.
802.11b
Explanation:
Channel bonding: 802.11n channel bonding allows two 20 MHz channels to be combined to form a
single 40 MHz channel, effectively doubling the transmission channel width.
ANSWER A:
WIKIPEDIA Source:
On 802.11 (Wi-Fi), channel bonding is used in Super G technology, referred as 108Mbit/s. It bonds two channels of standard 802.11g, which has 54Mbit/s data signaling rate.
On IEEE 802.11n, a mode with a channel width of 40 MHz is specified. This is not channel bonding, but a single channel with double the older 20 MHz channel width, thus using two adjacent 20 MHz bands. This allows direct doubling of the PHY data rate from a single 20 MHz channel, but the MAC and user level throughput also depends on other factors so may not double.
