We thank NSF for sponsoring the WiFO project.

Research:  WiFO system aims to overcome the WiFi overload problem by enhancing wireless capacity using the complement FSO technology which does not interfere with the WiFi transmission bands. When leveraged with the existing high-speed (Gigabit) Ethernet infrastructure, the proposed WiFO system based on the current FSO technology can provide Gbps per user via local FSO transmissions. Unlike stand-alone FSO technology, when integrated with WiFi, the proposed WiFO system provides high mobility via a novel system architecture that enables wireless devices to seamlessly and gracefully receive data simultaneously at different rates from FSO and WiFi channels based on their conditions.

Research opportunities:  We are actively looking for talented undergraduate students.

Educational Impact:     This  project has partly supported 5 PhD students and 3 MS students. Three PhD students working on this project have graduated. Because of the interdisciplinary nature of the project, the students have been introduced to three separate research areas: optics, circuit design, and communication/networking. The faculty members involved in this project continue to learn a lot from each other's research. The project also provided research opportunities for a couple of undergraduate students. One of the undergraduate students was a co-author on a conference paper about WiFO. In addition, the PI and co-PI plan to teach a special communication class where the students learn everything about communications from circuit design for transceivers to theory of modulation/demodulation, channel coding, and network protocols.
