Question

You are implementing an 802.11g wireless network in your office. What is the maximum number of wireless access points that you can implement within 30 meters of each other?

a) Two
b) Three
c) Four
d) Five

Answer 1

The maximum number of 802.11g wireless access points that can be implemented within 30 meters of each other without causing interference is three, as there are only three non-overlapping channels available in the 2.4 GHz band used by 802.11g.

Step-by-step explanation:

The question is related to setting up a wireless network, specifically concerning the 802.11g wireless standard. In the 2.4 GHz band used by 802.11g, there are 14 channels available, but only three of these (1, 6, and 11) are non-overlapping. Non-overlapping channels are preferred to avoid interference. Therefore, the maximum number of wireless access points (APs) that you can implement within 30 meters of each other, without causing interference, is three. This is because these three access points can each be set to one of the non-overlapping channels. If you implemented more than three APs, you would have to reuse one of these channels, resulting in potential interference and degraded network performance.
