Though it's nice to see someone/anyone recommending G* as a top pick for 2000, the article would hold much more credibility with me if the authors/analyst knew that the Iridium constelation uses LEO birds rather than GEO's as stated in the article.

"What separates Globalstar from the bankrupt Iridium is that Globalstar's network is based on 48 low-earth-orbiting (LEO) satellites instead of the geosynchronous earth orbit (GEO) satellites on which Iridium had relied. LEO satellites offer a distinct advantage in terms of both cost and performance because their lower orbits place them closer together, reducing the number of satellites needed to complete the network, and because they use "smart" telephones rather than relying on expensive onboard processing.

Don't get me wrong, I'm not complaining about the positive publicity. I believe G* will be wildly successful. You would think that at least one of the 8 authors would have caught that mistake.

It is the GEO satellites that get to have big coverage with a low number of "birds."

But, because they (GEO satellites) are 22,000 miles up (or -- whatever the exact distance), you are stuck with the time delay problem.

Also, I think you need more handset signal power to transmit 22,000 miles (as opposed to merely hundreds of miles).
