I am New to SI but I wanted to express thanks to Gary K., Jan, FUZFO, and others for there insightful posts. I have been lurking on this post (along with many others I'm sure) while accumulating a sizable position in ASND (LU as well; same thing someday perhaps). Hope we see 40 next week Tim :-) I read an interesting article in this week's Forbes regarding a new technology related to networking. I am not a tech expert like many on this thread. Can we easily dismiss the following technology? Granted, its written for the popular press and therefore may lack some substance, but can we read between the lines as to what they claim to be doing? ************************************** PUSHING PHONE LINES TO THE LIMIT "...a means to deliver fast Internet access over ordinary copper phone lines. There are many firms competing to open this particular bottleneck, but AWARE just scored a big point. In January, Compaq Computer, Intel and Microsoft endorsed the AWARE data transmission format. By December AWARE says it can get a modem to market that will handle up to 1.5 million bits per second, 26 times as much as the top speed of the fastest modems now commonly sold with computers. What's the trick? It goes back to that submarine probe. It is extremely difficult to send acoustic signals to a submerged submarine. Signals sent through ocean water never travel the same way twice. Temperature, the waves on the surface, salinity and other aquatic variables are constantly changing. The signals quickly get attenuated, or weakened, as they pass through the seawater. Similarly, in copper writing the signal also attenuates rapidly, and can suffer interference from broadcast radio signals or heat. AWARE'S solution: send 100 or so signals at once, each taking a sliver of bandwidth in the range of 4,000 Hertz to 400,000 Hertz. If one signal is corrupted, the others can pick up the slack. Data can be reassembled at the end. all this shuffling of signals and bits gets very messy, but today's high-speed signal processing chips are quite up to the task. It's not unlike what goes inside a cellular phone" Would like anyone's take on this. RobZ
