twisted light

Researchers found ways to reach incredible speeds of data rates and network speeds. The theory is called twisted light, which is basically twisted radio waves. Instead of 2 dimensional wave propagation, the radio waves are propagated in 3 dimensions. In 2003 Martin Harwit of Cornell University hinted that there might be one more testable effect to add to this GR toolbox. He was discussing a property of photons called orbital angular momentum (OAM). This is distinct from the more familiar intrinsic spin angular momentum of the photon, which is related to the circular polarization of light. Einstein’s general theory of relativity predicted the phenomenon. He referred to is as “gravitational lensing” and “time dilation”. The radio wave looks like a corkscrew, and with this technology researchers were able to transmit a lot of data very fast over a reliable connection. Scientists in California and Israel transmitted 2.6 terabits/second over the air. Also a team of researchers from Boston University and USC transmitted 1.6 terabits/second over 1 km of optical fiber. Another group has data rates at 32Gbps, however, the simplicity of their design can allow for much higher data rates in the future.One basic setup is an antenna that has a slice in it and slightly bent to produce the twisted radio waves. 

A lot of this material is still in the testing phase, and cannot be really applied to anything yet, but i think in the near future these researchers will figure out a way to be able to transmit data at high speeds over large distances. It is very expensive, especially if using the optical fiber method. 4G now a days is really good, and there isnt much wrong with it, but like i said, in the near future, i think this twisted light phenomenon can ultimately replace 4G and become the 5G.
