n802.15-4: Low-Rate, Very Low-Power
–Low data rate solution with multi-month to multi-year battery life and very low complexity
–Potential applications are sensors, interactive toys, smart badges,
remote controls, and home automation
–Data rates of 20-250 kbit/s, latency down to 15 ms
–Master-Slave or Peer-to-Peer operation
–Support for critical latency devices, such as joysticks
–CSMA/CA channel access (data centric), slotted (beacon) or unslotted
–Automatic network establishment by the PAN coordinator
–Dynamic device addressing, flexible addressing format
–Fully handshaked protocol for transfer reliability
–Power management to ensure low power consumption
–16 channels in the 2.4 GHz ISM band, 10 channels in the 915 MHz US ISM band and one channel in the
European 868 MHz band
