How to buy


Radio Bridge is excited to announce its flagship BridgeBee™ RF module for IoT connectivity. The BridgeBee™ module has a number of advantages over other modules on the market including incredible range and penetration through walls and other structures. The BridgeBee™ achieves this by running at 315MHz which (through basic laws of physics) will have range and wall penetration that is superior to any ISM band device running at 2.4GHz or even 900MHz. The protocol that the BridgeBee™ uses has been specifically designed by Radio Bridge to allow for FCC compliance and certification within this band.
