What is a recommended approach to avoid co-channel congestion while installing access points that use the 2.4 GHz frequency?

The correct answer is A. different nonoverlapping channels. In the 2.4 GHz band, there are only three nonoverlapping channels (1, 6, and 11 in most regulatory domains). To avoid co-channel congestion (interference between APs on the same channel), you should: - Assign different nonoverlapping channels to nearby access points. - This minim

Explanation

In the 2.4 GHz band, there are only three nonoverlapping channels (1, 6, and 11 in most regulatory domains). To avoid co-channel congestion (interference between APs on the same channel), you should: - Assign different nonoverlapping channels to nearby access points. - This minimizes interference and improves Wi-Fi performance.
