What is a Sigfox "base station"?
Deployed in the field by our local operators, base stations are composed of three major elements:
- An antenna, to receive messages over the air, usually deployed on high points or towers,
- A LNA or LNAC (low noise amplifier), to amplify the signal and filter noise,
- An access point, which understands these messages and sends them to the Sigfox Cloud.
Once interconnected with the Internet, they become part of our public network. They then start listening for all Sigfox messages sent by devices in the vicinity.
