Power line communication: tehnologies for the internet of things

Internet of Things (IoT) is a concept in which real-world things (physical objects) are seamlessly integrated with the virtual world of information technology. Each component of the Internet of Things is called a "thing" and should have a unique address. Things could be real world objects or virtual objects. This paper analyzes some of the proposed definitions of IoT. It provides the identification and explains the meanings of things. Considerations in this paper are focused on communication technology over power lines (Power Line Communication, PLC). Both the PLC technology and existing existing wireless communication technologies (Wi-Fi, ZigBee, Bluetooth, 6LoWPAN and others) are suitable for supporting IoT applications. These considerations include the principle and the frequency range of the system and its applications. Subsequently discussed are the PLC standards (IEEE 1901) that define data transmission over power lines. The paper covers two basic PLC standards: Low Frequency Narrow Band (LF-NB) and Broadband over Power Line (BPL).
