There is a really neat little newsletter that I peruse regularly called the Rural Spectrum Scanner from the Bennet and Bennet Law firm in DC. I recommend it. In any event they reported on the efforts of Republican senators Ted Stevens (Ak) and George Allen (VA) to pass bills that would apportion a lot of unlicensed band spectrum in the unassigned spaces in TV channel spectrum ranges. One bill addresses spectrum from 62 MHz to 692 MHz (ch 4 to 51 more or less) and the other 54 MHz to 698 (ch 2 to 51). Rural Broadband being the primary reason for this apparently. I thought this was fascinating as it addresses heretofore lower frequencies than I have ever seen considered for unlicensed band wireless. Why is that so important? The trade off in lower frequencies is lower bandwidth. But the range and penetration capability of these frequencies is excellent, even with unlicensed band power. Line of sight problems are the Numero Uno hassle for unlicensed band operators. Some of the newer modulation techniques could deliver fairly decent bandwidth at pretty healthy ranges that would actually penetrate objects somewhat. Amazing think of that.
