INTRODUCTION
Power Line Telecommunications (PLT)
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 PLTThe power grid
Is ubiquitous
offers last-mile connectivitysupports information-based services with stronggrowth potential
Is already in place, thus enhancing cost-effectiveness
Three main categories of new ICT-basedapplications --Energy Services, Telecommunication
services,A New category of value-added customerservices

WHY LIMITED EXPLOITATION?
PLT technology is young and still evolving; its capabilitiesstill need expansion
There is a lack of standardization and interoperability ofPLT-relevant products
commercial incentives to exploit such a telecom
infrastructure as PLT not yet been clear
Increased PLT transfer speed and reliability

BROADBAND OVER POWER LINES
Broadband over power lines (BPL)
Can plug the computer into any electrical outlet in the
home, instantly have access to high-speed Internet
Tested in several cities around the United States and the
United Kingdom
Two types of BPL service In-House BPL
Access BPL

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

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
PLTopens 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 goodgeographical coverage, relatively cheap
Faces problems -- PLT as a provider of the local accessinfrastructure,PLT-based development of applications and
services
play a significant role as a provider of necessary InformationSociety local infrastructure
