Tech Ping!...........

Cable is dead ~

Bwaahahahahaaaaa~ This multi channel capability on HDTV can now be unleashed to cram even more channels into the same old same old.

[ffusco]

a new statistical time multiplex?

Interesting. Ping for later...

And here I spent two years of high school insisting to my parents that “there IS no practical use for Algebra!”

(that was before I studied radio engineering and learned that FM Stereo is basically a quadratic equation...DOH!)

There also has been a breakthrough on FFT. This will also have a bandwidth multiplying effect.

The technology transforms the way packets of data are sent. Instead of sending packets, it sends algebraic equations that describe series of packets. So if a packet goes missing, instead of asking the network to resend it, the receiving device can solve for the missing one itself. Since the equations involved are simple and linear, the processing load on a phone, router, or base station is negligible, Medard says.

It looks like they are just sending error correction coding across multiple packets. Those codes take up bandwidth by themselves, so in a situation where you lose few or no packets you will transmit your real data slower because of that overhead (assuming uncompressible data). At a certain percentage loss that will be acceptable because you gain more from not having to resend packets than you lose on overhead.

It would be really nice if the amount of error coding is dynamic so you can reduce it to a minimum in a low packet loss situation.

some old sayings never lose their truth - such as “necessity is the mother of invention”

bottlenecks anywhere do not need government solutions (subsidizing telecom “infrastructure” development?)

they need understanding, R&D, private capital and open markets

without this latest technology the solutions to “bandwidth issues” could have even meant new and expanded infrastructure, but even then the solution that science and engineering, private capital and open markets came up with would not be any solution Obama and his ilk chose

repeat after Reagan - government IS the problem

Sounds like a RAID for a moving target.

Several companies have licensed the underlying technology in recent months,

It's good to see claims of technological improvement actually make it to market, rather than promising market availability several years in the future.

In a circumstance where losses were 5 percent—common on a fast-moving train—the method boosted bandwidth from 0.5 megabits per second to 13.5 megabits per second. In a situation with zero losses, there was little if any benefit, but loss-free wireless scenarios are rare.

Keep increasing the speed until you get packet loss.

Sounds like Forward Error Correction (FEC) code

My casual take on this after reviewing some of their published work is it’s founded on erasure codes. This is funny because I think there’s already products for the wired tcp universe that work the same way, plus storage implementations too.

So much in computing boils down to an encoding in some way or another.
