Haven´t you notice thats police and other forces could only communicate in simplex during Katrina? You must keep a simplex network with high power mobile units interfaced via mini-links in spread spectrum with the man outside is car for range (with one portable unit as reserve for each man), remote base simplex stations (via links) in various positions in a way that they cannot be knocked out all at the same time. And remember: never use a single band network for every one. That´s a dangerous "all eggs in one basket" very easy to fail or attack. Same band for all means channel restrictions when everybody is at the scene, and mutual unintendend interference via RF Blocking (too strong nearby same band radio signals sensitivity blocking on radio receiving part: THATS WHAT MADE 9/11 COMMS FAIL along with poor channel selection: the firemen without comms problems used the Port Authority radio relais because they didn´t know "it was down" :IT WASN´T!). Stop hasking for opinions from non technicaly oriented/non field expirienced people, they only do you harm. You will avoid wasting billions of Dollars. This comments are made in a friendly helpfull "spirit" for all the great officers in the field there in the USA.

This is great news. We have often discussed the urgent need for a universal frequency to be used in the event of any type disaster: A radio frequency (primary and alternates) developed for use by all first and secondary responders and that crosses state lines and any jurisdiction. Radios must be pre-programmed for these frequencies so immediate use is available. I would have loved to have served on this panel. Thanks and have a great day.
