Using Mobile Transmission Network Realize Power Line Broadband Communication Technology

In recent years, the area of mobile communications, China Mobile has scored brilliant achievements, however, with the state issuing 3G licenses and the in-depth reform in the field of telecommunications, telecommunications enterprises will be restructured and become all business operators, both mobile and fixed business operation. And mobile companies in the network, only to have wireless signal coverage and network connection between the base station and exchange ground optical transmission network, the lack of fixed telephone users cable network resources.Power Line Communication Technology also known as PLC, is adjacent to residential users from the low voltage distribution transformer 220V power outlets indoor power line high-speed data and voice communications technologies. Power Line Broadband Internet Access Technology as a new way. It does not need any network and telephone lines, and mobile and easy installation, and broadband access, compared with the general, it has great appeal.Electric power transmission line designed primarily for the low-voltage power line for signal transmission, as it makes the inherent characteristics of the electricity transmission network as a communications channel used, the transmission characteristics are not ideal. A lot of experimental results show that the low-voltage distribution network is rich in all kinds of noise, including background noise, such as narrow-band interference and impulse noise,...
