Re:The range is what? (Score 1)

The 0.9 miles doesn't really suprise me. The MaxStream radios are pretty much designed to be drop in serial extenders. Where I work, we use these (well not the zigbee ones, but their propritary OEM ones) for http://www.sontek.com/product/rsadp/rsaov.htmRiver Cats. There are a few quirks (nothing compared to the craptastic underwater modems that were wrapped in scotch tape) and every now and then we'll get a bad batch that has to be sent back, but these things go forever, and in most cases actually tend to work better than really long RS-232 cables. I think we can even upgrade the unit firmware wirelessly (although it isn't recommended). Given anything a good enough antenna and enough power and the range will jump up quite a bit. I think the R&D guys at work were playing with an omnidirectional bluetooth setup that worked over about 1/2 a mile. I don't really get the intrest over this paticular standard. MaxStream has been making drop in RS-232 wireless modems for quite some time and most of their other options actually are better solutions (spec wise). Most of these units are going to be stuffed into OEM systems anyways so it doesn't really matter if it's propritary.
