Dear TI,
I wonder why TI is not offerinig a port of their's Zigbee stack for a 433MHz transceiver. 2.4GHz is known for poor inhouse performance. Transmission at 433MHz performes much better, so why not offering a port for e.g. CC1100? Wouldn't it be natural to offer all the ISM bands (433/868/2400MHz) for Zigbee networks? Or would it be possible to port the TI's Zigbee stack on my own, but I assume the source is not open, right?
Any comments are appreciated. Thanks.
regards

ZigBee is specified to run on 802.15.4 and 433 MHz is not a supported PHY.
Zigbee runs on IEEE 802.15.4 which others have pointed out, and '15.4 is only defined for 868/900MHz or 2.4MHz, with the 900MHz variant being extremely rare by comparison. I know of quite a few Zigbee deployments on 2.4GHz but none in the 868/900 spectrum.
I've used 2.4GHz Zigbee inside buildings pretty successfully; if range is a problem then bolt-on the CC2590 RF front-end; it's wonderful.
Don't try to port the stack to a diffrerent protocol; it's akin to torture.
