Given RSSI-based triangulation, 5 Mbps sustained per client, up to 30 clients per classroom, and primary 5 GHz coverage, which AP placement is appropriate?

The correct answer is to place APs near exterior walls and corners of the building, and fill in the center area with a staggered pattern. This approach is suitable for RSSI-based triangulation, which relies on distinct signal strength readings from multiple APs to accurately locate devices. Placing APs near exterior walls and corners, combined with a staggered pattern in the center, creates overlapping coverage cells with varying signal strengths, optimizing triangulation accuracy. Mounting one AP in the center of each classroom would provide good coverage within that room but might lead to poor signal overlap and less effective triangulation between rooms. Placing APs in a grid orientation throughout the building, located as close as possible to the center of each classroom, is similar and suffers from the same triangulation limitations. Spacing APs evenly on both sides of the hallways would primarily cover hallways, leading to poor coverage and triangulation within classrooms.
