Our everyday life depends on performance of wireless communications
Every wireless device emits electromagnetic waves with information embedded in them. These waves do not travel in straight lines, instead they bounce on objects such as buildings, walls and furniture.
This uncontrolled propagation is source of all efficiency and security problems: such as limited download rate, call drops, coverage and deeps dropping.
In order to solve the mentioned problems, VISORSURF project has created an app that magically made objects around you aware of all the communication effort.
The VISORSURF project objective is to treat the wireless propagation as an app bringing forth the internet of materials.
The project has produced a number of prototypes called Hypersurfaces.
The Hypersurfaces are essentially canvas in which we can programmatically draw a merge of specially-designed metasurfaces and novel electronic nano-controllers, resulting in a reconfigurable metasurface, whose properties can be changed via a software interface. The controllers receive programmatic directives and perform simple alterations in the metasurface aspect of HyperSurfaces, adjusting their overall electromagnetic behaviour and attaining the required high-level functionality.
In terms of applications, VISORSURF introduces the concept of programmable wireless environments. According to it surfaces within a space, such as walls and ceilings in an indoors setting, receive HyperSurface coating. A central computer connects to and continuously configures the state of each HyperSurface unit, exerting control over the complete energy propagation phenomena within the space. In a wireless setting, this can lead to the complete mitigation of previously insurmountable signal-deteriorating factors, such as acute path loss, signal fading and sensitivity to user mobility, yielding unprecedented communication efficiency, security and long-range wireless power transfer. The concept carries the high promise of similar applicability to any scale, from smart cities, to industrial spaces, to the internals of sensitive imaging equipment.
