Canadian scientists have developed data transfer schemes that will include “reconfigurable smart surfaces” (RIS) to act as reflectors on existing wireless networks in urban centers.
The RIS is a panel of many individual reflective elements, each of which can modify and reflect the incoming signal. This modification can be controlled by an electrical signal, allowing the RIS to improve communication or generate signals useful for locating users on the network.
According to the study’s authors, it will be able to generate signals for cell phones by making the surface “smart”. As a bonus, these signals can also be used to get an accurate estimate of the phone’s location.
