The Massachusetts Institute of Technology (MIT) has developed a cheap way to amplify the signal of wireless Internet.
The “smart surface” called RFocus is an array of 3,000 miniature antennas that can be mounted on a wall or a regular board. In fact, this surface acts as a signal amplifier. It takes Wi-Fi from the router and transfers it to other devices.
This provides a cheap and easy way to amplify a Wi-Fi or 5G signal. At the first test, the “smart surface” was able to amplify the signal by 10 times and double the network bandwidth.
Unlike conventional Wi-Fi repeaters and mesh systems, this “smart surface” does not increase the coverage area of the wireless Internet, but rather enhances the signal - it works with any network and does not require additional configuration. This is a turnkey solution that can be placed anywhere.
The “smart surface” turns out to be universal and cheap - one antenna costs a few cents. And from such antennas you can assemble a Wi-Fi amplifier of any shape and scale the system by adding new modules.
According to hi-tech.mail.ru, potentially such antennas can be installed in the form of special wallpapers that do not require additional wiring. Such “smart surfaces” can help smartphone makers - you can put less powerful antennas to save battery power.
The inventors from MIT have not yet talked about when such "smart surfaces" will appear on the open market.
