【In the forthcoming years,Beyond-3G(B3G) environments will undoubtedly be deployed in most parts around the globe, permitting a world class solution for network interconnection, A B3G context enables the efficient cooperation of existing wireless technologies, including cellular-based(e.g. 2G/3G), broadcast-oriented(e.g. DVB)-in specific DVB-H, and Internet-based(WLAN/WMAN)networks, all relying on enhanced IP as the unifying layer. Hence, in this particular and yet to be deployed environment, mobile, systems and platforms will permit to provide enhanced services to all applications across heterogeneous access networks. This will effectively enlarge the scope of service deployment, availability and accessibility to the users】 Based on the paragraph above, it is shown that (98) will be used as the higher layer protocol to unify cellular networks ,broadcast networks and (99) networks, which is enabled by the context of (100).

All traffic, be it e-mail or streaming video, travels via a method called packet switching, (97)parcels out digital data into small chunks, or packets, and sends them over a network shared bycountless users.

But het hardware is designed to use even (95) power than other schemes, making it especially appropriate for such things as RFID tags, which must work for years (96) any external power sourc

including the use of low-loss low-nonlinearity(94)

which must work for years (96) any external power sourc

In order to maintain the reach of a typical 100G WAN transport system(~1500km), several system improvements have to be made to recover the lost (93)，including the use of low-loss low-nonlinearity(94)，Raman amplification,and stronger error correction.
