TRANSMISSION OF DATA OVER ELECTRIC POWER LINES
[attachment=372]
INTRODUCTION
aims at the utilization of the electricity power lines for the transmission of data
gains importance that every building is connected to the power grid that cannot be matched by either the telecommunications or cable TV wiring
provides new services to the users, which are difficult to implement by other technologies, e.g., remote electricity meter reading, broadband over internet and many
RELEVANCE OF PLT
The power grid
Is ubiquitous
offers last-mile connectivity
supports information-based services with strong growth potential
Is already in place, thus enhancing cost-effectiveness
Three main categories of new ICT-based applications --Energy Services, Telecommunication services, A New category of value-added customer services
WHY LIMITED EXPLOITATION?
PLT technology is young and still evolving; its capabilities still need expansion
There is a lack of standardization and interoperability of PLT-relevant products
commercial incentives to exploit such a telecom infrastructure as PLT not yet been clear
Increased PLT transfer speed and reliability
BROADBAND TO HOME
electricity and the RF used to transmit data vibrate at certain frequencies
If electricity spikes at a frequency that is the same as the RF then it will cancel out that signal and the data transmission will be damaged en route
BPL bypasses this problem by using medium-voltage lines -- the data can only travel so far before it degrades
