Bluetooth Zigbee and Wibree A Comparison of WPAN
Bluetooth, Zigbee, and Wibree: A Comparison of WPAN Technologies John Kooker CSE 237 A November 20, 2008
• Being adopted into Bluetooth specification • New name: Bluetooth Low Energy Technology Zig. Bee • IEEE 802. 15. 1 • Developed and licensed by the Bluetooth Special Interest Group (SIG) Wibree Bluetooth Background • IEEE 802. 15. 4 • Maintained and published by the Zig. Bee Alliance
Three Scenarios Watch Building Automation Wireless Stereo Headphones
Side By Side Band Bluetooth Wibree Zig. Bee 2. 4 GHz, 868 MHz, 915 MHz Antenna/HW Shared Independent Power 100 m. W ~10 m. W 30 m. W Target Battery Life Days – months 1 -2 years 6 months – 2 years Range 10 -30 m 10 -75 m Data Rate 1 -3 Mbps 1 Mbps 25 -250 Kbps
Side By Side, continued Bluetooth Wibree Zig. Bee Component Cost $3 Bluetooth + 20¢ $2 Network Topologies Ad hoc, point to point, star Mesh, ad hoc, star Security 128 -bit encryption Time to Wake and Transmit 3 s TBA 15 ms
Watch • Caller ID display for mobile phone – – Size Battery Life Small amounts of data 1 -to-1 communication • Solution:
Building Automation • Installing lighting control in an existing building – Already wired for power – Mesh network for resilience – Limited data transfer • Solution:
Wireless Stereo Headphones • Listening to uncompressed, stereo audio – 1. 4 Mbps – Close range – Recharge every several days • Solution:
Conclusion, and the Future! • Zig. Bee used to be the clear choice for very low power, low latency, low data rate, mostly asleep devices. • Preliminary designs for Bluetooth Low Energy Technology are just now being released. Bluetooth with integrated Wibree may steal that momentum (in non-mesh networks). – “Coming soon” for 2 years • Bluetooth is growing into a family of specs – 3. 0 adds High Speed (UWB)
