Low-cost system will improve communications among industrial machines (IMAGE)

The first signal-transmission device that can use an efficient data sharing technique called "backscattering" in a relatively untapped high-frequency range. By operating in the subterahertz frequency range, this low-power, inexpensive technology enables large numbers of devices, such as machines in factories and equipment in labs, to share information by efficiently piggybacking off of a singal sent by a central transmitter. This eliminates the need for numerous power-hungry signal transmitters in a wireless system.
