BACnet over Bluetooth?
December 19, 2009 – 1:36 pmAn interesting development developed recently in the wireless world. Bluetooth 4.0 was announced on December 17,2009. This version of the Bluetooth standard is aimed directly at the sensor market.
This got me to thinking. What impact this will have in the BACnet community?
Addenda 135-2008q, which introduced Zigbee as a BACnet data link layer, was approved in January, 2009. What will Bluetooth 4.0 mean for BACnet/Zigbee, or more generally wireless BACnet? My brief introduction (from the press releases) about Bluetooth 4.0 leads me to believe they’re trying to directly compete with Zigbee.
I think a lot of the same concepts (virtual MAC layer, caching, etc.) that apply to BACnet/Zigbee would also apply to BACnet/Bluetooth.
This is an interesting time in BACnet. With the work being done in IPv6 and the hope to work with the Smart Grid alliance, the committee has their work cut out for them.
