General Project Description There is a growing perception that copper-based access networks will
soon no longer be able to meet the ever-growing consumer demand for
bandwidth. This, along with a combination of regulatory and competitive
forces, as well as recent rapid advances and standardization of Passive
Optical Network (PON) technology, have prompted carriers around the world to
consider PON-based fiber-to-the-curb/home systems as a possible
successor to current copper-based access solutions. Concurrent with the
upsurge of PON-based wireline broadband access solutions, the growing demand
for advanced data-centric mobile multimedia services including multimedia
messaging, mobile video, mobile music, mobile TV, and IPTV, has accelerated
the development and deployment of new wireless broadband access technologies.
These emerging technologies, including High-Speed Packet Access,
fourth-generation (4G) mobile WiMAX, and cellular Long-Term Evolution
(LTE) are capable of delivering speeds
comparable to or better than current fixed-line broadband access systems �
up to
15-200 Mb/s peak air throughput per user. By leveraging the advantages of both of these access technologies combined on an integrated architecture platform, next generation Fiber-Wireless networks will enable the support of a wide range of emerging fixed-mobile applications and services independent of the access infrastructure. Several research efforts have recently emerged to address the integration of optical and wireless technologies into the envisioned fixed-mobile platform by combining the practically unlimited capacity of fiber-based PON infrastructures with the ubiquity and mobility of wireless networks. The overall objective of this project is to propose and devise all of the critical elements necessary for the implementation of a high-capacity, high-performance, cost-effective, converged fixed-mobile access networking solution that holistically addresses many of the key outstanding issues with both of today�s wired/wireless broadband access technologies. This novel architecture can then efficiently backhaul and support a mix of advanced wired and wireless multimedia traffic and services along with the diverse quality of service (QoS), capacity/rate, and reliability requirements set by these services. |
