CWDP Channel Planning and RF Design

Question 1

What is the primary goal of channel planning in a WLAN deployment?

Accepted Answer

Minimize co-channel interference between access points

Answer

Maximize the number of access points deployed

Answer

Increase transmit power across all access points

Question 3

What is co-channel interference (CCI) in a WLAN environment?

Accepted Answer

Interference between access points operating on the same channel

Answer

Interference caused by devices operating on adjacent channels

Answer

Interference originating from non-802.11 RF emitters

Answer

Interference caused by multipath signal reflections

Question 4

Accepted Answer

Frequency reuse planning

Answer

Adjacent channel planning

Answer

Random channel assignment

Answer

Dynamic Frequency Selection

Question 6

What is Adjacent Channel Interference (ACI) in wireless networking?

Accepted Answer

Interference between APs on channels that partially overlap in frequency

Answer

Interference between APs using identical channels

Answer

Interference from external RF sources outside the building

Answer

Interference caused by the same SSID broadcasted on multiple APs
