Welllll...... Zigbee is three protocol layers built on top of
802.15.4. Zigbee is a trademark, whereas 802.15.4 is not. The Zigbee
standard is only available to members at a five-figure cost, whereas
802.15.4 is available at nominal cost. Zigbee is a great name, and
much more pronouncable than IEEE 802.15.4, but they're not the same
thing.

Yup. 20ma continuous operation, 300 foot open-air range (measured),
50 foot range in an EXTREMELY RF-noisy environment.

| (...) Good question. I was comparting BT to other RF systems. But you won't typically run your motors at 100% load all the time, either. So typically on a Lego bot, motors will be the main power users. Add BT to a Lego Bot and the battery life will (...) (19 years ago, 1-Jun-05, to lugnet.robotics)
