Shown in the diagram is the antenna radiation pattern for a ceiling mounted access point (on the left). The transmit power (Ptx) is 14 dBm. The diagram shows that the cell edge occurs at a radial which is 70 degrees from the vertical. The cell edge power is -60 dBm. 

What is the actual antenna gain, in dBi, of the ceiling mount antenna in the required direction?

Using the ceiling mount antenna, what is the value of FSPL to the cell edge in dB?

Using the ceiling mount antenna, what is the distance in meters from the access point to the cell edge? Select the closest value in the FSPL table

Let’s see what happens if someone mistakenly mounts this antenna on the wall. In this case the antenna is rotated as shown in the diagram (right side). For the wall mounted antenna, what is the actual antenna gain at the required direction (i.e. 70 degrees from the vertical)?

For the wall mounted antenna calculate how far the signal will propagate in the same direction and using the same Prx and Ptx. Select the closest value in the FSPL table. Your answer is in meters.
