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?
BROADBAND OVER POWER LINES

BROADBAND TO HOME
special devices installed called repeaters take in the data and repeat it in a new transmission, amplifying it for the next journey
CT coupler allows the data on the line to bypass transformers
Transformer's job is to reduce the 7,200 volts down to the 240-volt standard
some carry the signal in with the electricity on the power line, while others put wireless links on the poles and send the data wirelessly into homes
PROBLEMS FOR PLT USERS
could cause malfunctions of your electrical equipment, such as battery chargers, audio-video systems
causes interference to important radio services, the user might be held responsible for the damage
Since all users share the same physical access, data sniffing can be done and security is a problem
achievable bandwidth and download rate is significantly lower than customers expect
To receive telecommunication services and energy from the same company will create a dangerous new monopoly
RECENT DEVELOPMENTS
More work required in the area of PLT hardware product development, production of appropriate standards and new software applications
improvements both in terms of capabilities (speed, reliability), investment and exploitation costs, interoperability
wide range of advanced software application in need of further investigations and field tests
A number of associated regulatory and standardization problems for commercialization
CONCLUSION
PLT

opens up new opportunities for the mass provision of local, last-mile access at a reasonable cost
offers a permanent on-line connection, as symmetric, two-way communication, has good performance, very good geographical coverage, relatively cheap
Faces problems -- PLT as a provider of the local access infrastructure,PLT-based development of applications and services
play a significant role as a provider of necessary Information Society local infrastructure
