Posted on Dec 28, 2011 | 0 comments

Both ZigBee and Bluetooth Low Energy are designed for ultra-low power wireless communicating devices. Below are some of their major differences:

  ZigBee Bluetooth Low Energy
Range 10-100m 50m
Networking topology
  • Local Area Network (LAN)
  • wireless mesh network
  • Up to 64k devices
  • Personal Area Network (PAN) or Body Area Network (BAN)
  • wireless star network
  • pair with up to 7 slaves
Modulation
  • Direct Sequence Spread Spectrum (DSSS)
  • Continue trying to send packets until successful packets delivery.
  • Frequency Hopping Spread Spectrum (FHSS)
  • Adaptive frequency hopping to find clear channel to help save battery life.
Bit rate ~100kbps ~200kbps
Setup time 20ms 3ms
Frequency
  • 868MHz in Europe
  • 900-928MHz in US and Australia
  • 2.4GHz worldwide
  • 2.4GHz
Hardware support In some consumer electronics and remote controls Most of the handheld devices support Bluetooth. BLE dual-mode is going to be included in all new devices.
Power consumption* 185.9uW/bit 0.153uW/bit
