I ran across this study a few weeks back:

Reading the executive summary, in their real world tests, NLOS/indoor
radios only worked about one mile. Outdoor mounted radios worked
maybe five miles. (I wasn't too impressed, in comparison to the
unlicensed gear I'm using)
I was particularly interested in this study, since the country they
are working in (Indiana) is probably very similar to my country.
