Ish Jane, PhD student at the University of California at San Diego in Electrical and Computer Engineering, has designed a setup that will provide ultra-fast and reliable 5G communications.
The new technology will help make 5G broadband practical for the everyday user. The fact is that fast wireless signals cannot travel far – and they are easily blocked by all sorts of obstacles: walls, trees or people.
Modern 5G broadband systems transmit data using a millimeter-wave laser beam, which they send between a base station and a receiver, such as a user’s phone. The problem is that if something or someone gets in the way of this beam, then the connection is completely blocked.
The graduate student and his team figured out how to get around this problem: they split one millimeter-wave laser beam into multiple laser beams, and each beam must now travel from the base station to the receiver. The idea is to increase the likelihood that at least one beam will reach the receiver when an obstacle is in the way.
The researchers tested the new system in the office and outside the building on the campus: it provided high bandwidth connections – up to 800 Mbps, with 100% reliability.
The signal did not stop or expire when the user avoided obstacles. During tests in the open air, the system worked at a distance of up to 80 m.
