When You Thought You'd Seen All Wireless Protocols...

... there's ZigBee. On Geekzone Mauricio Freitas goes into detail about this new protocol, and how it compares to Bluetooth and wi-fi.
"ZigBee is one implementation of the logical layer needed to implement the standard IEEE 802.15.4 ractified in May 2003. The standard intends to be a simple packet data protocol, with a low power requirement and narrow bandwidth requirements. Its maximum speed is 250kbps, compared to Bluetooth at 720kbps and wi-fi from 11mbps (although we all know real life applications will have different performance). [...] Because of its limited bandwidth it's not intended to be a wire replacement like Bluetooth, or a wireless network adapter like wi-fi. Examples [of its use] include:
• Wireless home security
• Remote thermostats for air conditioner
• Remote lighting, drape controller
• Call button for elderly and disabled
• Universal remote controller to TV and radio
• Wireless keyboard, mouse and game pads
• Wireless smoke, CO detectors
• Industrial and building automation and control (lighting, etc.)"
So, should my future Pocket PC have Bluetooth, Wi-Fi AND ZigBee?
