Hi Frank,

Only one problem with covering the third world, (and just where did the second world disappear to, anyway?), as far as I can see, if the average annual income of people in the third world is $2,500 (a SWAG on my part) and the cost of wireless satellite telecoms is $2,500/PA, just how are these people gonna eat? I suppose just like in the past, on what they can grow, bein' farmers and all and not having a heck of a lot of use for world wide connectivity.

Perhaps Bill and Craig are experiencing the same thing I am out here in the sticks in Tumalo, we can see the future of wireless telecosmic connectivity, we just can't see how to make it pay....

Mi Dos Centavos, Ry

Regarding Teledesic...

IMO, Teledesic is distancing itself from Motorola after the Iridium fiasco. Motorola has a lot of explaining to do, and Bill and Craig are waiting to hear their[MOT] answers.

Some Teledesic Facts.

Teledesic is not a public company.

Teledesic is scheduled to begin service in 2003.

The Teledesic system is designed to support millions of simultaneous users. Users will have two-way connections that provide 64 Mbps on the downlink and 2 Mbps on the uplink.

Teledesic will operate in the high-frequency Ka-band of the radio spectrum (28.6 - 29.1 GHz uplink and 18.8 - 19.3 GHz downlink)utilizing 288 satellites.

Teledesic QOS design parameters include:

Multi-megabit, Bandwidth-on-Demand (BoD). Terminals will be able to request and release capacity in less than 50 msec, resulting in extremely efficient statistical multiplexing.

Fiber-like Bit Error Rates (BER). Use of Forward Error Control (FEC) will provide BER of less than 10-10, creating an essentially noise-free channel.

Fiber-like availability. Availability of 99.9% or higher, enabled by Teledesic's 40 degree elevation angle among other features, will provide higher uptime than many terrestrial links.

Fiber-like latency. End-to-end (one-way) latency will be as low as 20 msec and less than 75 msec on all links of less than 5,000 km. Round-trip (two-way) latency will be less than 100 msec on most connections.
