Perhaps the next Iridium
Teledesic plans to throw a satellite network consisting of 288 plus spare sats in a low orbit. They plan to offer connections up to 64 Mbit/s for millions of users using the Ka-Band and call it "fibre-like"(see Abilene
to see what you can do with a fibre TODAY!). The extimated costs are planned up to 10 billion dollars and in year 2004 they'll begin to start their service.
My tip for the future: Don't call it fibre-like, call it cable-modem like. The guys at the WDM front are doing great work...
After all, Bill Gates holds part of it, so expect to find some sats in your garden
