Analysts at Oregon State University have imagined another innovation called WiFiFO (WiFi Free space Optic) that can build the data transmission of WiFi systems by 10 times, utilizing optical transmission by means of LED lights.
The innovation could be coordinated with existing WiFi systems to decrease data transfer capacity issues in swarmed areas, for example, airplane terminal terminals or cafés, and in homes where a few individuals have different WiFi gadgets.
Specialists say that late advances in LED innovation have made it conceivable to regulate the LED light all the more quickly, opening the likelihood of utilizing light for remote transmission as a part of a "free space" optical correspondence systems.
"Notwithstanding enhancing the experience for clients, the two major points of interest of this framework are that it utilizes cheap parts, and it incorporates with existing WiFi systems," said Thinh Nguyen, an OSU partner teacher of electrical and PC building. Nguyen worked with Alan Wang, a partner teacher of electrical and PC designing, to manufacture the first prototype model
“I believe the WiFO system could be easily transformed into a marketable product, and we are currently looking for a company that is interested in further developing and licensing the technology,” Nguyen said. The system can potentially send data at up to 100 megabits per second. Although some current WiFi systems have similar bandwidth, it has to be divided by the number of devices, so each user might be receiving just 5 to 10 megabits per second, whereas the hybrid system could deliver 50–100 megabits to each user.
In a home where telephones, tablets, computers, gaming systems, and televisions may all be connected to the Internet, increased bandwidth would eliminate problems like video streaming that stalls and buffers (think Netflix).
The receivers are small photodiodes that cost less than a dollar each and could be connected through a USB port for current systems, or incorporated into the next generation of laptops, tablets, and smartphones.
A provisional patent has been secured on the technology, and a paper was published in the 17th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems. The research has been supported by the National Science Foundation.
Recent advances in free-space optical technology promise a complementary approach to increasing wireless capacity with minimal changes to the existing wireless technologies. This paper puts forth the hypothesis that it is possible to simultaneously achieve high capacity and high mobility by developing a communication system called WiFiFO (WiFi Free space Optic) that seamlessly integrates the recent free- space optics technologies and the current WiFi technologies. We quickly portray the WiFIFO building design then talk about the primary commitment of this paper that is enhancing the limit of the proposed WiFiFO framework. In particular, we consider the issue of force allotment for different FSO and WiFi transmitters with a specific end goal to accomplish most extreme system limit for given spending plan power. A numerical model of the joined limit of FSO and WiFi channel is inferred. We demonstrate that the force portion issue for WiFiFO can be approximated well as an arched enhancement issue. To that end, a calculation taking into account inclination not too bad strategy is created. Reenactment results show that the proposed calculation, together with system architecture can provide an order-of-magnitude increase in capacity over the existing WiFi systems.
