> This [uplink and downlink data speed] is pure speculation by a reporter, right? I'd take them with a grain of salt, Mike. Here's a slightly older take on Spaceway's expected speed from Interavia Business & Technology, Feb99 p45. Sorry I can't provide links or urls to any of these sources. "Moving to the more obviously well-founded projects, the oldest geostationary one is Hughes Communications' Spaceway. This was launched some years ago as a global (or rather multi-regional) system using two GEO Ka-band satellites (probably HS 702s) at each of four obviate locations, connected by intersatellite links. Each satellite would generate 48 beams. Bandwidth per channel would be 500 MHz, for a total effective bandwidth per satellite of 6GHz. Downlink data rate would be 92 (or 108) Mbit/s, top uplink rate 6Mbit/s. The system would use USAT terminals with 0.7 or 1.2m antennas. Hughes is also looking at a non-geostationary MEO (10,352km orbit) constellation employing 20 satellites, also using Ka band, to give true global coverage. Latest Hughes thinking is to roll out the service over the USA only, probably in 2002, to see how the market develops. The parent company Hughes Electronics has authorized spending of $1 billion on start-up costs. There have been discussions with "a lot of possible partners", says corporate spokesman Richard Dore, but no announcements can yet be made."
