Fiber Wireless Ultra High Speed

A mm-wave Fi-Wi network. An optical fiber backbone (red) provides broadband connections between the central offices and antenna base stations. Then, the base stations wirelessly transmit 5-mm-wave (60 GHz) signals to customers. Within buildings and homes, the short-range wireless signals can provide high-speed connectivity (faster than 1 Gb/s) for a variety of wireless, high-bandwidth communication devices.

Yet while all these notebooks, netbooks, and tablet PCs are becoming more and more popular, their explosive growth also poses a problem: these wireless devices are hogging the already congested lower microwave frequency region of the wireless spectrum.The advantage of bimodal Fi-Wi systems is that they can enjoy the strengths of both optical and wireless technologies – specifically, the inherently large bandwidth of optical fiber and the large, unused bandwidth in the mm-wave wireless spectrum. For this reason, a hybrid system has the potential to provide very high data transmission rates with minimal time delay.
