India has led the world in internet shutdowns for five years running, according to online freedom monitors Access Now. With the world’s largest biometric ID database, a pioneering digital payment system for daily transactions and a flagship space and satellite program, India knows the power of connected technology. But when trouble brews with political unrest

Some of the key technologies in smart industries and smart factories are the industrial Internet of
The researchers tested data transmission by laser over 53 kilometres from the Jungfraujoch to Zimmerwald near Bern. Credit: ETH Zurich Optical data communications lasers can transmit several tens of terabits per second, despite a huge amount of disruptive air turbulence. ETH Zurich scientists and their European partners demonstrated this capacity with lasers between the mountain
A 64-element active RIS aided wireless communication prototype developed by the researchers from Tsinghua university. Credit: IEEE Transactions on Communications Reconfigurable intelligent surface (RIS) has become a promising technology in future 6G communications. Thanks to its high array gain, low cost, and low power consumption, RISs can improve spectral efficiency and reduce power consumption. The

In a recent study, the team, led by Debdeep
An international research team has developed reconfigurable antennas using artificially engineered structures called “metasurfaces” that can help solve the issue of limited frequency resources for wireless communications. These antennas provide variable response to waves of the same frequency but different pulse width. Thus, it provides a new degree of freedom to these antennas, making for
