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.
Auditoriums are challenging environments for wireless design, as they often have a large number of users and devices in a relatively small area, creating high demand for bandwidth and capacity. To provide adequate RF coverage and performance, auditoriums typically require a high-density AP design, which involves deploying more APs than usual, using directional antennas, reducing transmit power, and selecting non-overlapping channels12. A high-density AP design can also help mitigate interference from other sources, such as Bluetooth devices, which operate in the 2.4 GHz band3. Auditoriums do not necessarily require the use of 80 MHz channels or DFS channels, as these options depend on the availability and regulation of the spectrum, as well as the trade-off between throughput and channel reuse .
