This Technology Will Increase Your Wi-Fi Bandwidth By Ten Times
Meet WiFO, This is a hybrid of Free-space Optic and Wi-Fi. The prototype system that has been created employs advancements made in LED technology thus allowing for the high-frequency modulation of IR light in wireless transmission.
Thinh Nguyen, Associate Professor of Electrical and Computer Engineering at Oregon State and also the Lead researcher for this project said, “Using light to transmit signals is an old technology that dates back when the Roman soldiers communicated with each other using a simple flash code with mirrors.”
By making use of components that are low-cost and off-the-shelf, the prototype from Oregon State is capable of dataspeeds upto 100 Mbps. However, the LED component can only carry out transmission within 1 meter radius. In order to tackle this limitation, the system autonomously makes switches between a number of LED transmitters (affixed to a ceiling or other high points) and the already existing Wi-Fi RF thus imparting a seamless coverage of a particular area.
The original idea for this system sprang up during discussions between associate professor Nguyen and Alan Wang – university co-worker and assistant professor of electrical and computer engineering at Oregon State. Both colleagues then went on further to collaborate on the project and designated the task of coming up with a prototype to graduate students. The results were there within 8 months with students coming up with a prototype that proved the concept. The team has already received a provisional patent for their creation. Currently, Associate Professor Nguyen is looking for a company to work with him and the team to develop the device further and eventually bring it to the market. He is hopeful and says, “I wanted all of my student to contribute to this project, because I think it’s going to be big.”
