The REAL reason for the delayed rollout - finally. Courtesy Yahoo board. ========================== Note from Geneva #2 by: ayupduck (35/M/de) 14866 of 14889 Don't know if this was clear to others, it wasn't to me, but the current 38 sats are not enough for "global service". The issue is that gaps appear in roll out regions. Here in Geneva, that means that their are occasional periods of no service (about 2 minutes long) due to the location of the Italian gateway. Meanwhile I've asked about the gatewaz roll out plans. Didn't really get any information that was not already known. There are nine operational gateways currently - they are listed in the press release from monday. Everybody is very tight lipped on where the next gateways might be. On the 1000 PSTN connections, G* techies (I trust these guys much more than the IR people) say that this is a simple function of the gateway to PSTN link and is very easy, and cost effective, to upgrade if demand requires it. More later. -------------------------------------------------------------------------------- Posted: 10/13/1999 4:25 am EDT as a reply to: Msg 14821 by ayupduck View Replies to this Message ============================ Another note from Geneva by: dischandler 14883 of 14889 I visited the Qualcomm stand and spoke to one of their engineers. He confirmed the same as Ayupduck with the rolling coverage gap. It dropped my call to Napa, CA and it took about a minute for to pick up the sat signal again. The engineer said the same thing, another 4 satellites up and this issue disappears. On the quality side: unbelievable. Could barely tell the difference and my father on the other end didn't know it was a sat call until I told him.

This is probably an indication as to why service wasn't initiated with 32 sats.... -------------------------------------------------------------------------------- Posted: 10/13/1999 11:34 am EDT as a reply to: Msg 14883 by dischandler ============= shaggy - coverage holes by: ayupduck (35/M/de) 14886 of 14888 It's a combination sat/GW problem according to the G* people. There are some pretty complex mathmatics involved here which I won't go into (partly because I'm not sure I fully understood). But basically the holes can be addressed by either more sats or more gateways, and the holes will be addressed as soon of the next set of sats are operational and in correct orbits (i.e. the sats from next weeks (?) launch. -------------------------------------------------------------------------------- Posted: 10/13/1999 11:42 am EDT as a reply to: Msg 14869 by shaggy_64
