RFocus Smart Wall Amplifies Wi-Fi Signal 10x

A project by the Massachusetts Institute of Technology's Artificial Intelligence Laboratory (MIT CSAIL), RFocus, is described in accompanying documents as a "smart surface" consisting of more than 3, 000 tiny antennas that act as a kind of lens. Only in this case we are talking about focusing radio signals on the desired devices.

The creators of miniature wireless electronics are constantly faced with a serious problem - a lack of space for placing antennas. This is what the RFocus project is designed to solve. Already at the stage of experiments, using an experimental model, it was possible to amplify the received signal by 10 times and double the channel throughput.

The development team led by Venkat Arun used an array of more than 3, 000 antennas with the appropriate software, resulting in a significant increase in signal strength. Its main advantages are low cost (one mini-antenna costs only a few cents) and low power consumption compared to traditional systems.

So far, researchers have no concrete plans for the future use of RFocus. Most likely, it will find its application in smart homes and businesses of the future. Also, this technology can be useful for solving some of the problems of the upcoming 5G networks.
