What is Power Line Communication (PLC)?
PLC refers to the use of existing electricity cable infrastructure to carry data signals which can be used for voice, Internet, telephony, video etc.
How does PLC work?
PLC works by transmitting high frequency data signals through the same power cable network used for carrying electricity power to household users. This requires devices that combine the data signals with the low-voltage supply current in the local substation to bridge the last mile. Residental modems are used in order to filter out the data signals and to feed them to various applications (e.g.PC/Internet, telephone, etc).
What application areas does PLC provide?
PLC offers end-users a broad spectrum of applications and services including broadband internet access, Voice-over-IP, multimedia services, home automation, and energy management.
Is PLC a new technology?
The technology has been around for a while and at a low bandwidth. It has been used by power utilities for simple telemetering and control of electrical equipment in their networks. This means voice and data transmission via the mains supply voltage network goes right through to power sockets in the building.
What bandwidth can be achieved with PLC?
The PLC technology is known as a "shared medium" technology. Several buildings with individual terminals (PCs, telephones, etc.) that are connected to the same distribution node share the available bandwidth. Dynamic bandwidth management ensures optimal usage and hence all users have sufficient bandwidth available at all times. Compared with a point-to-point connection (the traditional telephone connection), a shared medium represents a far more economical solution.
What is the transmission rate of PLC?
With the latest PLC chip development, overall maximum speed can reach up to 45Mbps, i.e. 27 Mbps downstream and 18 Mbps upstream.
