Researchers set world record for wireless data transmission speed
Imagine for a moment being able to transfer the entire contents of a Blu-ray disc or five DVDs over a wireless connection in a mere two seconds. Impossible, you say? For the everyday user and consumers at large, that's true. Heck, it might take more than two seconds to toss a set of DVDs across the living room. But for Professor Ingmar Kallffass and his fellow researchers, that type of wireless speed just became possible.
In the current issue of the Nature Photonics magazine, researchers outline a method for wireless data transmission at 100 gigabits per second. In successfully conducting their experiment, the researchers set a new world record, and they did it by transmitting data at a frequency of 237.5GHz over a distance of 20 meters in the laboratory.
Previous experiments topped out at 40Gbps over 1 kilometer. To achieve the latest world record, the researchers used a photonic method to generate the radio signals at the transmitter.
"Our project focused on integration of a broadband radio relay link into fiber-optical systems," Kallfass explains. "For rural areas in particular, this technology represents an inexpensive and flexible alternative to optical fiber networks, whose extension can often not be justified from an economic point of view."
As it stands, this type of transmission over long distances requires conventional antennas, but in time, these can be replaced by miniaturized antenna designs in compact form factors for indoor use.
