That article still mentions the use of mud pulse telemetry, though. Considering the low bandwith of mud, pulling a cable all the way down is probably not an option, or else it would already be done. I wonder if it's possible to use a relay of short-range wireless transmitters, with heavy error correction? Bandwidth of mud telemetry is 'up to' 40 bps or 250 with compression, according to this: http://www.bakerhughes.com/products-and-services/drilling/drilling-services/measurement-while-drilling/axcelerate-high-speed-mud-pulse-telemetry http://www.bakerhughes.com/products-and-services/drilling/dr...
