A directional antenna points down a hall. A client behind the antenna, in the opposite direction, has a weak signal a few meters away. What is the client sitting in?
Select an answer to reveal the explanation.
Short Explanation
The antenna is a flashlight pointed down the hall, and the client is standing behind it. You are in the weak rear of the pattern, not in the beam. Turning the country code will not light that side.
Full Explanation
A directional antenna concentrates energy in a lobe and is weak behind it. This client is a few meters away in the opposite direction from the hall the antenna points down, so the weak signal is the rear of the pattern. The main lobe is not equally strong behind the antenna. The country code does not mute the rear of an antenna. A weak signal is not an empty DHCP scope. The client has not failed addressing. The radio is simply not aimed at them. The client sits behind a directional antenna. The lobe points the other way, so the client is in the weak rear of the pattern. Check one live client after the change and leave the rest of the floor alone until that client matches the result you expected. Confirm the symptom on the next attempt before changing anything else. Exam caveat: a directional antenna still leaks somewhat to the rear. Do not assume the rear is zero, and do not assume it is usable for a client. Measure it. Operational check: move the client into the hall the antenna points down and confirm the signal jumps.
