Power line communication or power line carrier (PLC), also known as Power line Digital Subscriber Line (PDSL), mains communication, power line telecom (PLT), power line networking(PLN), or Broadband over Power Lines (BPL) are systems for carrying data on a conductor also used for electric power transmission.
Electrical power is transmitted over high voltage transmission lines, distributed over medium voltage, and used inside buildings at lower voltages. Powerline communications can be applied at each stage. Most PLC technologies limit themselves to one set of wires (for example, premises wiring), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically the transformer prevents propagating the signal so multiple PLC technologies are bridged to form very large networks
objective shifted from broadband plc to new arena of broadband network for mobile user based on Wimax and LTE....there is tough comptetion going on for future of mobile broadband....
ReplyDeletewhen u change things forever....there is no going back...
Internet is spreading like never before and people will find themselves incomplete without it after starting using it, thus they need to connected at every time,Indian Railways (IR) are the preferred choice of transportation for most of the Indians and which takes 24hrs in an avg. for a long journey, having a start towards pervasive network, we are moving towards designing a network which can sustain broadband even while moving at high speed, at present this segment stay disconnected from world while they are on journey even though IR posses 42000 km OFC laid down through out the track.
ReplyDeleteWe started with searching for a suitable technology for this, surely PLC doesn't support this as it cannot cross beyond Transformer, Present wireless technologies which can be considered are WiMAX and LTE. Out of these two WiMAX spectrum is been auctioned, so we started with that.
then it was the turn to find the suitable Testing support for our design, soon we found Qualnet Simulator which has support for WiMAX. We tested the present network for our scenario, definitely result need some improvement and design needs optimization, as such high number of Hand-off's in such short time will break the link and can't support QoS.
I came up with a mathematical model for my network, which are very much near to what i have expected and the results are very much intuitive. When the load on the network is increasing then distributed threshold assignment which is done dynamically is very much helpful. But when I am trying to get the results from the simulation then they are not matching....still analyzing the reason for the obtained results...
