What are two safeguards used by 802.11n that can protect against interference caused by channel bonding? (Choose two.)
A) convolutional coding rate
B) Dynamic Frequency Selection
C) Phased Coexistence Operation
D) variable guard interval

Question

Quizplus · Accepted Answer

Dynamic Frequency Selection (DFS) is used to prevent interference with radar systems that operate in the same frequency band. Phased Coexistence Operation (PCO) is used to manage interference by dynamically adjusting the timing and power of transmissions. Convolutional coding rate and variable guard interval are used to improve data transmission reliability, but they do not specifically address interference caused by channel bonding.
