Wireless communication is becoming ever more important in our increasingly connected world, but it isn’t without its problems. In an effort to make wireless communication more efficient, scientists have developed a new type of antenna array made up of tiny crystals. This array has the potential to improve the speed, range, and accuracy of wireless communication by using multiple antennas to focus the signal in specific directions. It could also reduce the amount of energy needed to transmit data. This breakthrough could open up new possibilities for wireless communication, making it more reliable and cost-efficient.
