19 megabits on 3G
haligan writes "Bell Labs research arm announced the development of two prototype chips that would allow mobile devices to receive more than 19 megabits of data per second on 3G networks." Power consumption is low enough for cel phone type applications.
now I can stream it directly to my 3G phone, while waiting in line at the video store.
I can't even get 0.056 Mbit (i.e. 56K) on a COPPER WIRE between myself and the ISP.
Wow I would actually be able to host a web site off my cell phone and be able to handle a slashdotting...
All we need now is an infrastructure to take advantage of it!
That'll be what? 10 more years before see anything like it in the U.S.?
That's more than 6 megabits per G. Incredible!

With the piece-meal rolling out of 3G phones and coverage, when can I really expect to take advantage of these data rates? My supposed 3G phone gets a good deal less than 128 kbit/s, not to mention the obscene $/data rates. Speaking of, does this not seem to you like the chicken and the egg: Expensive per kilobyte/megabyte rates for 3G phone data downloads won't change until more people sign up... but more people won't sign up until the service gets cheaper! Grrrr.
Acording to the lecture i attended last year by a very sensior vodaphone engineer this bandwidth is the maximum available. It isnt all used for data in fact they reserve a few channels for voice and a few for data (depending on the area past usage etc) also if you are the only user then things get faster still. However it wtill wont be that fast most 3g implementations relie on doing TCP/IP on top of TCP/IP on top of another protocol or 5 yes there are 2 tcp/ip stacks. This is so the phone network can keep you inside there network
If the new stuff can only receive at such high speeds while still transmitting at low speeds, it's the old broadcast model again, with "producers" and "consumers" of content just like television. Phones were supposed to be so people could talk to each other, not have everyone receive the same stuff from AOL-TW. A fast one-way data phone is just another way for TV to follow us everywhere we go. From a human communications point of view, a device with 1 megabit send and receive is a heck of a lot more interesting than 8 kbps send, 20 megabits receive.
People tend to forget that sending out ACK packets upstream greatly effects the download speed of a connection. Asychronous connections with low upstreams often become saturated and drag down the downstream to unbearable levels.
I suppose it could make sense in certain situations. 802.11a can supposedly give up to 72mbps by using the 5ghz spectrum. If you need wireless connectivity beyond 802.11(x) trasmission range, this might work. Mostly, I'd be concerned about latency more than bandwidth. Every noticed a fraction of a second delay while talking on a cell phone? That fraction is an eternity if you are a CPU. Lastly, allow me to kindly tell you to forget the "only a kid/stupid idea" apology stuff. We'd still be in the stone age if it weren't for kids coming up with brilliant ideas. Don't assume an idea is stupid, simply because stale old farts like me have some preconceived notions about how things are supposed to work. Never apologize for thinking.
