FLEXIBLE RF PROTOCOL
Laird Technologies’ embedded transparent protocol simplifies the integration process by allowing seamless plug-and-play
installation. As each unit receives raw data, it manages over-the-air protocol to assure successful communication. Headers,
data packet length, and CRCs are not required. Broadcast communication to all devices or address packets to a specific
destination using unique MAC addresses embedded in each unit.
