Researchers claim a new technique could triple the maximum theoretical broadband speeds possible using copper wires, potentially paving the way for faster transmission in areas where full fibre infrastructure isn’t possible.
A study at the University of Cambridge found that twisted pairs of copper wires, the type used in the UK and in many other countries, could operate at a frequency of 5GHz – five times higher than what is currently used – by deploying a small, inexpensive component called a Balun.
