A client on the Wireless network who is farther away from the access point and using less power is masked by a client who is closer to the access point and using high power. What is this condition called?
  1. Hidden Node condition
  2. Near/Far condition
  3. Degraded throughput condition
  4. Interference condition
Explanation
Answer - B - This condition is known as Near/Far.

Key Takeaway: All client stations have a fixed power output. However, in some cases, a low-powered client station that is a great distance from the access point could potentially become an unheard client if other high powered stations are very close to the access point. The transmissions of the high-powered stations can raise the noise floor to a higher level that would prevent the lower-powered station from being heard. This condition is referred to as Near/Far condition.
