Crucially for data storage, this free flow means that the spins of the electrons in question would be able to align themselves with those of the data-storing atoms, giving a clean signal.

There, a piece of hardware called the concentrator unit plucks the data off a fiber-optic network, reformulates it into a signal at 2 to 30 megahertz and injects that signal onto the power line.

Current wireless protocols alter the spin angular momentum (SAM) of radio waves to hold info, and by combining both methods the team was able to pack eight data steams into a single signal, resulting in the mouth-watering number noted above.

Power companies and networking startups have spent years touting a technology called broadband-over-power lines, or BPL. In those systems, the utility sends a data signal across existing wires at a much higher frequency than electricity, so the two signals don't interfere.

As soon as a helicopter goes beyond the 80-mile zone covered by land-based radar, its signal is picked up by the offshore platforms, with the data then returned to the airport.

Bluetooth uses a radio signal in the 2.4-gigahertz range to connect two or more devices for sharing data when they're close to each other.
