An engineer changed the TPC Power Threshold for a wireless deployment from the default value to -65 dBm. The engineer conducts a new post deployment survey to validate the results. What is the expected outcome?
B is correct , deafult is -70dBm and now -65dBm which is increased that wil definetely increase the cell size as well since there is nothing mentioned about data rates limitations
Default threshold is -70dBm. Range is from -50 to -80. Increase this value (ie between -70 -50) causes the AP to operate at higher transmit power rates. Decreasing the value has opposite effect
B is correct
The transmit power was tuned based on the 3rd AP ' hearing' the NDP advertisements at -70 dBm. When this threshold is changed to -65 dBm, the AP needs to increase the transmit power and that increases the cell size. It will also increase channel overlap not decrease.

--> Answer B is correct
Provided answer is correct. By reducing the power threshold from the default 70 to 65 it is forcing the controller to ramp up the power levels to meet this requirement. When you increase the power levels you increase the cell size. Which in affect will do the opposite of your suggested answer and increase channel overlapping rather than decrease it. Please don't guestimate but rather Validate.
I think it is A - because the default is -70, so -65 would decrease the Cell size and reduce overlap
