IMO satellite telephony has a very poor business case. (Disclaimer: my opinions are based more on I than G*). I wants to sell trumpet-size handsets for $1750 in the States and for $3000 in France. You know the States better, but I just can not see anybody buying one in France. Secret service agents, perhaps, or an occasional nutty millionaire. Cellular network covers everything, including 40 km out to sea, and roaming aboard is very common. The problem is that the time-to-market for satellite systems was a dozen years and it shows. Bulky phone, reportedly bad voice quality, short battery life, practically no coverage indoors, bad coverage if shadowed by tall buildings. System will be improved no doubt, but there are technical constraints. One is the distance to the base station. Its 1,400 km minimum for Iridium (satellite happens to be right above you) and 40 km maximum for GSM, which put severe limitation on the voice quality, phone size and battery life. Also, as it was earlier noted on this thread, when a $1 component fails the whole satellite may be rendered useless. The problem is further accelerated by limiting the number of satellites (both I and G* did this). Why? To save costs. What does that do to quality I can only guess, but the distances grew further for starters. IMO competent systems were designed initially but what we are getting now is scrape-through solutions. And look at the market. Its a well known secret that there are no hordes of cash rich Eskimos waiting. The users will be the seriously wealthy with a penchant for remote outdoors and no sense of chic (well, that's still perhaps 50% of the American population). - rajala
