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.

When we send and Excel spreadsheet with pivot tables we often get new blanks and new lines of what seem to be / appear to be the same sort words or data. I have wondered if these are transmission errors?
