System designers are thinking of precision timing as a layer, one that supports the entire stack, from hardware to software and applications.

Today, we are surrounded by digital electronics. Devices that work with analog electronics are very rare. Computers, telephones, cameras, CD players, printers, radios, and TVs all operate with digital ...

Scientists have been working for years to harvest the power of ambient radio waves to power small devices, and these days there is hardly a richer source of these signals than Wi-Fi networks.

For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from ...
