10x Wi-Fi signal reinforcement invented

Engineers have developed a smart plate that acts as a mirror or lens, focusing radio signals onto specific devices on both sides of its surface.

Mobile devices may have problems withWi-Fi signal reception, as their small size does not allow to place a sufficiently powerful antenna. However, a team of researchers from the Massachusetts Institute of Technology proposed an alternative solution.

They developed a smart RFocus plate that increases signal strength by almost 10 times, simultaneouslydoubling the average channel capacity inindoors. This effect is achieved due to the fact that there are more than 3,000 tiny antennas on the sheet with special software that organizes them and ensures maximum reception. As a result, the plate collects radio signals across the entire plane, and then immediately reflects and focuses them on each side, directing the signal to the desired device.

According to the developers, the prototype presentedRFocus is relatively inexpensive and consumes little power compared to traditional systems. Moreover, despite an almost tenfold improvement in the signal, the device only concentrates the signal, and the antennas themselves do not produce additional power.

The team says the plate still requiresrefining the design, reducing the size and improving the design. Ultimately, they plan to create an inexpensive sheet that resembles a piece of wallpaper that will cheaply and effectively boost the signal of Wi-Fi, 5G networks or Internet of Things devices.

In addition to improving existing ones, researchersNew data transmission systems are also being developed.  We previously reported on the development of a new data stream converter for 6G networks, providing speeds of more than 100 Gbit/s.
