Flexibly reconfigurable fiber-wireless network using wavelength routing techniques: The ACTS project AC349 PRISMA

A dynamically reconfigurable fiber-wireless network using flexible wavelength routing techniques is proposed by the PRISMA project, which offers a ``forecast-tolerant{''} solution for handling a wide variety of wireless services and capacity demands as may emerge in the fast evolving market of mobile communications. This approach can considerably increase the operation efficiency of wireless networks for broadband nomadic services (wireless LANs). It also supports the evolution from GSM and GPRS towards UMTS, and the entry of new operators and/or services into the liberalized mobile communications market. The system has been implemented in a field trial and has been operated successfully with real users and broadband nomadic services. The system concept is ready for further development into products.
