What is the best method of gathering attenuation measurements from any building materials or objects?
A.
After measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall or object on one side and your measuring device 0.67 meters (2 feet) away from the wall or object on the other side. Take measurement and compare the difference.
B.
Use the pre-built attenuation values in the predictive design tool.
C.
After measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall or object on the other side. Take measurements and compare the difference.
D.
Look on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material provider's websites.
What happens if you're working in office space with 10x12 offices? You can't measure the RSSI in 5 meter (16.5 feet) space or put AP 4 meters (13 feet) away from wall or object. The answer is C. After measuring the RSSI in free space 1 meter ( 3 feet) apart, put an AP .32 meters (1 feet) from the wall or object on the other side. Take measurements and compare the difference.
A is the right answer, based on the linear are where the free space is flat, and it is on 5 meter from the AP.
