Yes, the SA issue to which you refer is very informative. Good discussion on satellite and cellular communications. I think the next 2-4 years will be very interesting as far as which technology leaps ahead, although I think all technologies will continue to play significant roles. Geostationary satellites (that's about 40,000 km high, remaining over the same spot on the earth) have been used for comm for over a quarter of a century (boy do I feel old). They play a major role in the telephone, television, and other transmissions across continents that we all use. But they are very expensive. In addition, we are running out of space in space :-) The problem is not lack of space per se, but lack of enough separation to keep the comm satellites from interfering with each other. 3 degrees or so is as close as you can pack them, and there are only 120 such positions possible around the earth. There are things you can do with varying frequencies, etc, but the point is that we are reaching limits on what we can do at geo. That is one reason why so many companies are pursuing low earth orbit satellites (several hundred to a few thousand km up). There are a lot of advantages to that as far as space, nearness to the users, etc, but they are much tougher to orchestrate and link together. Iridium and teledesic, IMHO, are going to face extreme challenges getting the costs down. Teledesic is at risk of not every going up because of that. I favor less expensive space solutions, such as what Orbcomm is pursuing (message rather than voice), but that is a personal preference. Wireless, especially with GSM technology, is playing an increasing role in regional communications, and is something to be reckoned with. We are just starting down that path in the U.S. Regardless of who or what leaps ahead, one thing is fairly certain: the built-in telecommunications infrastructure, the combination of land lines, undersea cables, satellites, and wireless, will all have to become one large synergistic system. And that system will be digital. And whoever gets their inforamtion over that system in the most cost effective way will make a bundle. That is one reason why I live DGIV as much as I do.
