--OT-- Wireless satellite access still has many problems From Nicholas Negroponte's Being Digital... to paraphrase Using air has many difficulties. Signals can interfere with eachother very easily, so you have to use "exclusive predetermined parts of the spectrum". You can increase the capacity and effectiveness of air, by "reusing parts of the spectrum" or rather parts of that spectrum that were avoided by other signals. However compared to fiber (and the "infinite" bandwidth possibilities we haven't fully explored) air is a very scarce medium. And you can always lay more fiber. Pg 24 Iridium has had many problems with service outages, incorrect billing (lost calls), and reliability. The sun is set to begin its next cycle of Solar Flares. This will cause huge telecommunications problems in the years to come. Reliability of systems that use satellites will be very poor. Ground based cell systems would be the most reliable wireless for the 3rd world. regards, Jay
