Video and photos of the work, which started in 2006, show a decommissioned airplane loaded with row upon row of potato sacks that look like large, lumpy passengers. The sacks sit eerily still in the seats as the engineers collect data on the strength of wireless signals in various spots.
The Boeing engineers added some complicated statistical analysis and the result was a proprietary system for fine tuning Internet signals so they would be strong and reliable wherever a laptop was used on a plane.
Boeing says the system also ensures Wi-Fi signals won't interfere with the plane's sensitive navigation and communications equipment.
"From a safety standpoint, you want to know what the peak signals are, what's the strongest signal one of our communications and navigation systems might see from a laptop or 150 laptops or 350 laptops," Boeing engineer Dennis Lewis explains in a video.
In a nod to the humor in using a tuber to solve a high-tech problem, researchers dubbed the project Synthetic Personnel Using Dialectic Substitution, or SPUDS.
The company says better Wi-Fi signals can be found already on three Boeing aircraft models flown by major airlines: 777, 747-8 and the 787 Dreamliner.
