Preface
Zigbee Evaluation BoardThe low-power XBee 802.15.4 and extended-range XBee-PRO 802.15.4 use the
IEEE 802.15.4 networking protocol for fast point-to-multipoint or peer-to-peer
networking. The XBee 802.15.4 platform features:
low-power point-to-multipoint/peer-to-peer networking Fast 250 kbps RF data
rate No configuration needed for out-of-the-box RF communications 128-bit AES
encryption.
