re: HDR So I can view like FM or PCM with the base wave having side bands, or are saying it's a separate spectrum allocation? Thanks much. G

As far as service, it would provide a single time multiplexed 2 MBPS channel for your use. Lowest service rate would be about 38k bps, wiht about 50-55 users per cell site active at any one time on a singel cell. for super cells, this is like a 14 km diameter, but for microcells, this could be as low as 100 meteres. If you look at the COX cable Saunders stuff, it could be strung down a street and put at every light pole. Would provide alot cheaper entry point for something like the Road runner service than they have now .... HDR may provide a new access medium which can be done wihtout the existing voice oriented carriers involved at all. Well, then, what are we all waiting for. Let's draft a business plan (right here on this thread) for a CDMA-based HDR-only ISP operator. A brand new breed of ISPs. Seems to me wealth is waiting to be created. It's not quite GBLX, but it can be very significant in many locations. Especially if I heard Jeff Jacobs correctly ... that operators can roll HDR out at around $30-80 per month flat-rate for 2 mbps Internet access. I live in Silicon Valley and I have been waiting for @Home/TCI for well over four years now. DSL got my business recently. Why isn't HDR happening already? I'll pay $80/mo for 2 mbps any day. 3G may never happen, but seems to me we could/should be hopeful of HDR. A followup quesiton for engnieer ... I thought (e.g. GG said) CDMA was perfect for bursty data (like Internet traffic). I don't understand why the 1.25 MHz channel per user air interface? Isn't that going backwards, chopping the spectrum up into channels, more like TDMA? What am I missing, could you enlighten me?
