There is no such thing as protected spectrum if we're talking about public safety in the US. If you are willing to break the social contract you can transmit on any frequency any time with as many transmitters as you can afford. And you don't have to colocate near the transmitter and so get caught. If a government wants to protect a swath of spectrum for some use it needs to get buyin from the masses, a good way to do that is to get every single person to vote and to ensure they trust the counting of those votes. This government also wants to avoid angry foreigners, so it needs to avoid foreign entanglements and so not trade with despots or governments that exclude a portion of their populace from voting, and avoid direct involvement in any wars. It also helps to be a smallish country and not have any former or current colonies (Phillipines, Guam, Cuba, Haiti, Puerto Rico). This way there is no interest in using the spectrum aside from greed which you can combat with large fines.
If you want safe effective communications without buy-in, use wires, preferrably a mesh. Thankfully, there is a scale here. Less evil = less problems = less cost, firefighters can be more trusting of the public than the police, and the police can be more trusting of the public than the army. -- Daniel On Mon, 24 May 2004 [EMAIL PROTECTED] wrote: ]True, Don't forget about attacking the air interface (OFMD) wave form. ]There are now software defined radios that can cause havoc without going to ]the IP layer. 2.4 Ghz saturation is not far away there will be no need to ]worry about an attack the noise floor will never let you link up..
