I. Introduction(Heading 1)
The collection of electricity information in a power grid is a complex task, which requires the use of efficient communication technologies. The traditional power grid system uses wired communication or power line carrier technology for data transmission. However, these technologies have several limitations, such as low data transmission rate, high cost, and susceptibility to electromagnetic interference. To overcome these limitations, high-speed power line carrier (HPLC) and high-speed radio frequency (HRF) technologies have been introduced.
