Theory validation Formula of indoor space transmission loss (1) Power on antenna port:8dBm (2) 30 meters free space transmission loss: -60dB (3) Antenna gain:G=2.1dBi (4) Partition loss + multi-path loss: -25dB 30 meters

(5) The signal strength of point (S): PR=8 +2.1-60 -25= -74.9dBm

S Formula of space transmission loss L (dB) = 20lgd (m) + 20lgf (MHz) - 28 +α d is the path between the antenna and the testing point, f is the carrier frequency, α is transmission loss in : glass = 6~10dB

partition =10~15dB

prefab board =20~30dB
