Researchers developed a low-power, inexpensive technology that allows numerous devices to share information efficiently using high-frequency signals. This advancement utilizes backscattering, a technique where a reader sends a signal to a tag, and the tag reflects it back, enabling real-time monitoring and large-scale applications.
Researchers have found a low-power, inexpensive way for large numbers of devices, such as machines in factories and equipment in labs, to share information by efficiently using signals at untapped high frequencies.

Researchers have found a low-power, inexpensive way for large numbers of devices, such as machines in factories and equipment in labs, to share information by efficiently using signals at untapped high frequencies. The technology could immediately enable low-cost, efficient real-time monitoring in industrial settings, such as tracking the condition of manufacturing robots or detecting gas leaks in refineries, by eliminating the need for power-hungry signal transmitters. The researchers said that with some engineering improvements, the technology could be used for large-scale applications like smart cities and agriculture. The technology is an advanced version of a device that transmits data in a wireless system, commonly known as a tag. The new tag can support data transmission for a large network of devices using a technique called backscattering. This is where a central reader sends a signal to a sensor tag to gather information, and the tag reflects this ambient signal directly back to the reader. Backscattering is already used in simple systems like smart payment and building entry cards, but until now has only been possible at low frequencies. The low frequency limit poses a problem when many devices try to communicate at the same time because when more signals are introduced, they are more likely to run into one another and get jumbled up. Conventional backscatter designs also have slow communication speeds, as lower frequency signals have limitations on how much information can travel back and forth at onc
