Engineering Seminar/ Paper Presentation: Broadband Powelrine Communication
Broadband Powerline communications are sets of equipment, software and management services that when overlaid on the electric grid provides users with communication means over existing “power lines”. The new technology operates in the 1-30 MHz and can deliver data rates up to 200Mbps.
The rationale behind providing high bit-rate data services exploiting the power grid resides in the vast infrastructure in place for power distribution, and the penetration of the service could be much higher than any other wire line alternative.
In spite of the renewed interest in Power line communications, this technology still faces several technical challenges and regulatory issues: the power line channel is extremely difficult to model; it is a very noisy transmission medium; Power line cables in the 240V secondary distribution systems are often unshielded, thus becoming both sources and targets of electromagnetic interference (EMI); transformers can introduce severe distortion in the absence of bypass couplers.
