Although 802.11n can achieve data rates of 300 Mbps when using 40 MHz of bandwidth in the ISM band, one of the main challenges of deploying a WLAN in this frequency range is _________.
A) intersymbol interference
B) co-channel interference on channel 6
C) excessive multipath interference on channels 1 and 11
D) interference from the U-NII band

Question

Quizplus · Accepted Answer

Co-channel interference, especially on commonly used channels like channel 6, is a significant challenge in deploying WLANs in the 802.11n frequency range. This is because many devices and networks may use the same channel, leading to interference and reduced performance.
