Scientists at Brigham Young University (USA) have found an alternative to expensive Mesh-systems, with which you can increase the range of Wi-Fi access points. According to the developers, this can be done without hardware intervention - using the standard signal processing mechanism of the device.
The idea proposed by the researchers is to constantly maintain the router in communication with the device that is farthest. The new protocol was called On-Off Noise Power Communication (ONPC), and its essence is that every second only 1 bit of information is transmitted between the router and the gadget.
Thus, the router will "understand" that the gadget is still using Wi-Fi, and will continue to broadcast the signal in amplified mode.
After conducting a series of experiments, the developers noted that they managed to increase the radius of the standard Wi-Fi router by 67 meters. The proposed method can be used on top of the existing wireless protocol, and you can deploy it on almost any router, just updating the firmware.
Researchers note that extending the signal range does not imply maintaining the same high speed as in an area with standard signal strength. Most preferably, such a software improvement for all kinds of sensors and elements of a smart home. The project authors do not report on the release dates of the public version of the developed software.
