Expansão de rede local utilizando Power Line Communications (PLC)

Abstract

This paper deals with data transmission technology Power Line Communication, presenting its operation, types and applicability of use. The case study designed to evaluate this technology was limited to the expansion of a local network using Power Line Indoor Communication technology, which has shown world growth in their use. An analysis of service quality was conducted through tests in the computer lab of the Elementary School Colonel Virgílio Távora, which analyzed the flow metrics, latency and packet loss. These tests done on a comparative basis between standard Ethernet Category 5e network and the Power Line Indoor Communication HomePlug AV. A huge advantage was observed for Ethernet Category 5e standard for throughput and low latency. On the other hand, in the tests, Power Line Communication Indoor maintained as the Ethernet standard Category 5e, a null rate in packet loss. Another analysis was the quality of experience, where users who used this technology at their homes, were interviewed, and through a form prepared subjectively evaluated and reported on their experiences. As a result, a satisfactory user experience has been reported, taking advantage of all the benefits that technology provides and also recommending it to others. Another interesting factor was the use of Power Line Indoor Communication together with Wi-Fi, expanding the reach of wireless networks. Finally, it is concluded that the Power Line Indoor Communication is a technology recommended for use in environments where there is no need for large data traffic and low latency, but where it is desired to expand the range of the local network in a easy and efficient way.
