Path Loss

 
Path Loss
Path loss between the transmitter and receiver is a key consideration when designing a wireless
LAN solution. Expected levels of path loss, based on the range between the transmitter and
receiver, provide valuable information when determining requirements for transmit power levels,
receiver sensitivity, and signal-to-noise ratio (SNR). Actual path loss depends on the transmit
frequency, and it grows exponentially as the distance increases between the transmitter and
receiver. With typical indoor applications, the path loss increases approximately 20dB every
100 feet.
