NEW QUESTION 48
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
