Did you know that the electricity cables that had been supplying the electricity needs of households and industry, it can be utilized as a point of internet connection.This is really real and have started on trial in Indonesia. internet connection technology that uses electricity network is the PLC (Power Line Communications) is not an ordinary PLC in use on industrial machines.To know more about the PLC (Power Line Communications), please refer to the fine description of this article."PLC is a continuation of the Power Line Communications, a technology that uses electric cable line connection that can be used on existing electricity grid to provide electric energy supply, and at the same time can also be used to transfer data and voice transmission. Maximum speed that can be achieved using this technology more or less close connection speed fiber optic data transmission uses, ranging from 256 Kbit / s to 45 Mbit / s.PLC or commonly called 'the internet via the nets', is an internet connection using the power cord PLN. So far the internet connection using the communication cable with RJ11 or RJ45 port will be replaced with power cable / meshes directly from PLN's power cord. Yes, because it uses electromagnetic fields generated by current delivery akitivitas (hukumMaxwell). We do not need to bother to the cafe, just wrote tide line at home, we already can surf in cyberspace as for other penertian of PLC (Power Line Communication), which uses electricity cable network for communication and data transmission.The electric current that can actually be used to be a "carrier" (carrier) signal and data information. Because the data itself can be converted from digital to analog format
PLC is a technology that uses electrical cable connections that can be used on the electricity network that has existed for memeberikan supply of electrical energy, and at the same time can also be used to transfer data and voice transmission. Maximum speed that can be achieved using this technology more or less close connection speed fiber optic data transmission uses, ranging from 256 Kbit / s to 45 Mbit / s. We also do not fear electrocuted, because the Internet connection is (BPL) using a carrier that played at a low frequency AC-voltage electric cables. If we want to access the Internet from an outlet like this, we must have a "modem" BPL special and is different from a conventional modem-based telephone connections (dial-up) or other.With the wired telephone network technology, we are free to access the Internet without leaving a chance if there is a phone that will enter. This is a significant excess of the telephone network through the electrical wires owned by the State Electricity Company (PLN) is linking from one house to another house.Schematic Internet Via Power CableTheoretically, the electric cable can indeed be used to bring the "packet data" such as telephone cables and fiber optic kaber commonly used for Internet connection. and their application to an internet connection called BPL (Broadband Over Power Lines).This internet connections (BPL) using a carrier that played at a low frequency AC-voltage electric cables.If the analogy, supposing in dalem power cable that can make We electrocuted, it can disusupin data packets and even the sound of AC current in a wave of lower frequency than the AC power wave of his own. Proverbial in a cable as if there are two different cables, one is setrumnya, another for the internet connection.How to send data over an AC currentIn principle, data transmission via cable stun is done by laying communication signal containing data under power frequency. The process of laying the data signal requires a low-scale wave frequency, 1-50 MHz.The data flow through optical fiber cables of high voltage. Then at the beginning of the process, the signal data signals before entry into the ISP's Icon +. From here, data from superimposed into the medium voltage power flow, then divided into two paths: via fiber optic cable and high voltage cables. The data were first ride into the electricity distribution substation, to change the voltage of electricity - from medium voltage to low voltage.With PLC, the telecommunications signals (data, image, voice) can be superimposed or injected kejaringan low voltage (10-30 MHz) from an external data network. The analogy, electric current flows such as sea water to produce waves and foam. Is the current wave, while the froth of noisenya. Noise is utilized by the PLC technology to deliver voice and data signals.The technology initially responded less because many enthusiasts who hesitated, afraid to shock and not feel safe. However, now the users of services held subsidiary of PLN, PT Indonesia Comnets Plus (Icon +), can be enjoyed right conveniences available.icon + is a company that since the initial set up to support the development of advanced telecommunications and information technology. Icon + can provide excess capacity to meet growing demand for network services or higher bandwidth and wider coverage area by utilizing the right of ways.Attendance Icon + PLN especially for large families, especially those living in Java-Bali, can suppress the use of toll calls from Telkom. PLN family who lived in Jakarta do not have to worry about swelling telephone bills every month, although they had to speak Ngalor ngidul long distances. Use of the Internet through electrical currents have the advantage that is more quickly accessed than if the conventional and obviously less expensive because it only relies on electrical currents. Facilities that can be used all over the room as long as there is PLN's electricity network. Users simply plug the telephone cord into the electrical outlet using the power line Comunication (PLC). In addition to the Internet, they usually use the talk with family outside of Jakarta, but still large family communities PT PLN. If PLN open connections in other cities, so users who are in Jakarta will be able to interact with users in other cities. Ease, it is also a toll-free conversations and clearer. The phone number used was only three to five digits. To speak out the city or long distance does not need to use the area code as a sign the pay is more expensive due to long distances.The existence of technology via the power cable also makes users are not scared by the noise increase in phone rates. For the Internet, users simply pay per month subscription fee to the provider, while the cost of credit, do not need to bother anymore. During a year in use, users in Housing PLN had never experienced equipment problems. All well, except if the power goes out, which means also disconnected the telephone network. In utilizing the Internet, do not be afraid of breaking in the middle of the street while engrossed in chatting or surfing. The existence of a tool that makes all other family members can still use the phone line from Telkom, although there are family members who were surfing. In addition, there was no need extra cables, which means reducing the cable clutter at home. So, if the government allowed Icon + spread the wings to work on common customers, not just the big family of foreign policy, is not impossible that one day society, especially the difficulties a customer of Telkom, busy-busy installing telecommunications equipment alone at home. Moreover, by utilizing the flow of electricity in communication, no telephone toll-term costs swelled from too much use of the telephone. "Good Government Party Allowing Expansion of this technology. for me personally as a consumer Tel ** *** & Indo feel disadvantaged due to the intermittent signal, not to mention the small bandwidth and slow internet speed like snail.
