An architect needs to plan an 802.11ac wireless upgrade for a university building. What is one reason that it is important for the architect to identify auditoriums?
A.
Auditoriums typically require a high-density AP design for RF coverage.
B.
Users in Auditoriums often have Bluetooth devices, which can be a source of interface in the 5 GHz band.
C.
Auditoriums typically require the use of 80 MHz channels to meet bandwidth requirements.
D.
Auditoriums often require the use of DFS channels for sufficient 20 MHz channels.
I go for answer A as the ACDP Certification Study Guide states: "A high-density WLAN is typically seen in an auditorium... High-density networks require additional planning and design than basic coverage."
Tend to agree - as Aruba states
" To DFS or Not to DFS?
With as many as twenty 20-MHz channels (different vendors support slightly different numbers), the 5-GHz band with DFS now has sufficient channels to achieve high performance in a 500-seat auditorium without channel reuse in dozens of countries.
Without DFS channels, the goal can still be achieved, but the radios will be oversubscribed and the per-client average throughput will be much lower"
