A new WiFi technology delivers 10 times the current speeds

WiFi gets a light-assisted boost, with a new LED-based system that can up transmission bandwidth by a tidy 10x. Researchers at the Oregon State University who invented this new technology claim that it can be integrated with present-day WiFi systems, helping alleviate bandwidth issues that generally plague congested locations--public access areas and offices for example--where a multitude of devices are online concurrently.

These advancements are thanks to recent developments in the ability to modulate LED light--the process of rapidly switching the light off and on to conform with the data signal being transmitted. Since this technology is light-based, it works in free-space systems where the transmitting and receiving stations are within line of sight of each other.

“In addition to improving the experience for users, the two big advantages of this system are that it uses inexpensive components, and it integrates with existing WiFi systems,” said Thinh Nguyen, an OSU associate professor of electrical and computer engineering.

This new wireless technology, christened WiFO, can theoretically transmit data at up to 100 mbps, a speed that some of today’s new standards can match. However, WiFO is capable of delivering 50 to 100 megabits per second to individual users; current-day systems are capable of providing only a tenth of that speed per user. The eventual gains are better user experiences across the board. Also the technology can purportedly be manufactured using relatively simple components--photodiodes that cost less than a dollar each--that are connected via a USB port for current systems. All of this implies its time to market can be expectedly short.

Given that a provisional patent has already been secured for this technology, it could make its way to upcoming laptops, tablets and smartphones soon.
