Researchers are working on antenna that allows for transfer of 10 HD movies in 1 second


Hate waiting around while you transfer a file from one phone to another via Bluetooth? No worries, researchers at Georgie Tech have you covered. According to MIT Technology Review, the researchers “have drawn up blueprints for a wireless antenna made from atom-thin sheets of carbon, or graphene, that could allow terabit-per-second transfer speeds at short ranges”. Translation? They are working on an antenna made of graphene that will allow you to download/upload at speeds of 1 Tbps — or the equivalent of 1,024 1 Gbps Google Fiber connections.

The range on this antenna is estimated to be a meter which means it will likely be used for device-to-device data transfer as opposed to for the Internet. If you are able to decrease the distance to somewhere around a few centimeters, in theory transfer rates can be as high as 100 Tbps. As MIT Technology Review points out, at 1 Tbps you could transfer 10 HD movies from one phone to another in about one second.

Of course this antenna is far from market ready. Heck, it is only at the blueprint stage. Still, it is of things to come. Excited? Hell yeah, it will make it easier to transfer my pron collection from device to device.

    [@Peter] Shannon ‘s sampling theory is correct for 2 level signals, but you can have multiple phase and amplitude levels and get more information bandwidth in a physical signal bandwidth. So, TV channels can have 4 video streams plus several audio channels and services in a 6 MHz band. The problem is that you have to hit the right phase and amplitude spot to decode the right “symbol” and if anything is nonlinear because of distortion, noise, propagation or antenna response, it won’t decode correctly. Read about 8VSB if you’re really interested (or have trouble falling asleep).

    Please tell me that youre heading to keep this up! Its so great and so important. I cant wait to read a lot more from you. I just feel like you know so substantially and know how to make people listen to what you might have to say. This blog is just too cool to become missed. Terrific stuff, genuinely. Please, PLEASE keep it up!

  • You need a transmitter and receiver pair to hook up to those antennas, and memory buffers to slow it down and store it on the receive end, and transmit buffer to speed it up on the transmit end. Wideband antennas aren’t that hard, I’ve built lots. Well, not terahertz BW.

    Assuming Shannon was right, we would need ~200 THz to transmit 100 Tbps. This is almost visible red light. Wouldn’t it be easier (in the sense of less development) to have a short optical cable at hand for these cases (and reach even higher transmission rates)?
