Bluetooth 4.0 ­ Low Energy

Joe Decuir


Bluetooth has been re-invented. Bluetooth Low Energy is optimized for two things: simple applications; run on coin cells for years. The layers from the antenna up to the applications support middleware are all published in the 2010 Bluetooth 4.0 specification. The first wave of those applications are in development; dozens will be specified in the next year. Soon there will be support in mobile phones, PCs and other internet gateways.

This talk will address a few questions: what is Bluetooth Low Energy? how does it work? how does it compare to classic Bluetooth and to Zigbee (IEEE 802.15.4)? what is it good for? where do we learn more?


Joe Decuir has been working in networking and communications for 3 decades. As a standards architect for Cambridge Silicon Radio, he contributed to the Bluetooth 4.0 specification, and he is currently working on applications that use it. He has been giving presentations on computer and communications topics to IEEE chapters around the US and Canada. He also serves as the Northwest Area chair for IEEE Region 6, supporting Sections in Alaska, Oregon and Washington.
