Check out Maxstream. I think it's [url]www.maxstream.net[/url. Their Zigbee Pro line I think should be in your price range ($30 per module if I remember). Not sure exactly what you mean by 32 bit data though, since data transmitted is data transmitted. Specifying a maximum separation is also more useful than specifying a minimum separation

The range on those units is 1.6km outdoor line-of-sight. It's only 100m indoors with stuff in the way.

You can also get their stuff from other places like Digikey.
