While fiber optic network have become unimaginably fast over the years, they’re still hindered by their physicality. Their wires can limit where data can be transported and the affordability of the fastest connections. It now seems that network scientists have discovered a way to eliminate those pesky cables while also offering faster speeds.
By twisting protons, networks are able to fit more data into each transmission, surviving any interference from turbulent air. By passing the light through a specially designed hologram, photons can be supplied with an optical angular momentum that allows it to carry more than binary code. If the light’s phase and intensity are right, data can be beamed over much longer distances.
The research team was able to successfully test a link over a one mile stretch in an urban environment in Germany so it could be tested by interference caused by taller buildings.
While there’s still a lot to be done before this approach to wireless networking can be used in a practical sense, it’s still exciting for any wireless network heads out there.
