12.2.4 Recommendation for best wireless communication
Effective wireless communication is susceptible to noise interference in the environment, and
distance and barriers between the sensor transmitter and the gateway.
1) Installation direction. When installing equipment, in addition to the direction of wind
direction, also need to consider the direction of wireless transmission. In the direction
shown, pointing to the gateway will get a better signal.
2) Distance. Path loss occurs naturally with distance. This device is rated to 10km by line of
sight (in interference free environment and without barriers). However, typically you will
get 1~3km maximum in real life installation, which includes passing through barriers.
3) Barriers. Radio signal are blocked by metal barriers such as aluminum cladding. Please
align the weather station and gateway to get them in clear line of sight through window if
you have metal cladding.
The table below show a typical level of reduction in signal strength each time the signal
passed through these building materials (RF signal reduction for reference):
