質問 97
During a post-implementation survey, you have detected a non-802.11 wireless device transmitting in the area used by handheld 802.11g scanners. What is the most important factor in determining the impact of this non-802.11 device?
- A. Channel occupied
- B. Airtime utilization
- C. Receive sensitivity
- D. Protocols utilized
正解: B
解説:
Airtime Utilization is a per-channel statistic that defines what percentage of the channel is currently being used, and what percentage is therefore free. Airtime usage can come from: Data traffic to and from client devices. Interference from WiFi and non-WiFi sources. Management overhead from APs and client devices. https://wyebot.com/2019/06/06/understanding-airtime-utilization/
