Make Wireless Terabit Uploads in One Second


Imagine transferring enormous amount of movies to a mobile phone in few seconds. Well, this is the research going in Georgia Tech University. A team of researchers have made blue prints for a wireless antenna out from Graphene that allows a terabit transfer to occur in a second.

This can be done at a range of one meter. With short ranges, it is even possible to transfer 100 terabits in a second. Electrons in Graphene have the ability to move with zero virtual resistance. In order to make the design of the antennae, the team came up with the idea of shaping Graphene into strips that are narrow having a width of 10-100nm and 1micrometer length. This will allow the Graphene sheet to transmit and receive terahertz frequency. The electromagnetic waves present in the terahertz frequency will then interact with the plasmonic waves (These waves are oscillations of electrons present at the surface of the Graphene strip) so that they can transmit and receive information


It is still true that wireless networks still continue to remain as a bottleneck in transferring data between devices. Antennas can be made out of Graphene with much smaller dimension (in the order of micrometer and nanometer) when compared to metal wire antennae. Also it is easy to incorporate them in small objects. However, Antennas don’t work alone; they do rely on other components.

The team has just submitted a theory. They will have to work on the manufacturing part. When you work with materials, their properties change when they come into contact with other materials. So this is one process that will involve tedious work.

The journal of selected areas in communication of the IEEE will publish a paper later this year, that will describe the design, Graphene`s electronic properties and the optimal configurations of the antenna. It is expected that the team from Georgia Tech University will build a prototype of the Antenna in a year.
