Why should you use caution when using multiple APs?
What will be an ideal response?
Although overall performance and coverage seem to improve with more APs, having stray wireless signals outside your security perimeter is risky. Unlike a wired network with a clearly defined area of operation, wireless signals are transmitted through the air, so enforcing physical security for wireless signals requires careful placement of APs. There is also the risk of co-channel interference, in which signals from APs interfere with each other. In an environment with multiple APs, you must be careful when arranging them so that overlapping signals do not share the same channel (frequency).
