If you've been scouting an unobtrusive range extender for your ZigBee network, look no further than Digi International's XBee Wall Router. If you'll recall, this isn't the first ZigBee extender sharing the same name
(acquisitions tend to do that), but this little bugger simply plugs into a standard AC socket and "patches areas within a ZigBee network where signal erosion or loss occurs due to distance limitations or air interference." Additionally, it serves to create "multiple pathways, increasing the redundancy of the mesh communications," and the US flavor even includes an integrated mounting tab to prevent "accidental unplugging." Sound like just what you need? If so, you can snag one right now for $79.
