ZigBee and BLE

Business Comparison

ZigBee is older. It has gone through some iterations.

ZigBee has a market mindshare, but not a lot of shipments yet.

Market barriers: connectivity – ZigBee is not in PCs or mobile phones yet.

Technical Comparison

Zigbee is low power; Bluetooth LE is even lower. The detailed analysis depends on specific applications and design detail, not to mention chip geometry.

The ZigBee stack is light; the Bluetooth LE/GATT stack is even simpler.

• Remember: GATT – Generic ATTribute profile.

Going Forward

ZigBee has a lead in developing applications and presence.

Bluetooth low energy has improved technology, and a commanding presence in several existing markets: mobile phones, automobiles, consumer electronics, PC industry.

Replacing “classic Bluetooth ” with “dual mode” devices will bootstrap this market quickly.
