P2821 is a high-speed Power Line Carrier (HPLC) + Broadband Low-Power Wireless (HRF) dual-mode concentrator routing communication module designed for the digital energy IoT. It complies with the State Grid/Southern Power Grid industry standards and features dual-mode adaptive networking capabilities. The "high-speed carrier" and "high-speed wireless" modes serve as backups for each other, complementing each other's strengths. The product exhibits excellent resistance to attenuation, frequency offset, and interference, effectively addressing the communication "island" issue in HPLC single-mode communication. It enables stable high-speed data transmission in harsh power environments, significantly reducing communication latency and improving the success rate of high-frequency data collection.

As the Central Control Office (CCO), the P2821 is equipped with a 32-bit processor and 8MB of memory to autonomously manage various network nodes. It works in conjunction with Station (STA) to perform functions such as HPLC+HRF dual-mode communication, master control, topology identification, and analog data acquisition. It finds wide applications in power data collection, distribution network automation, industrial Internet, smart homes, and other fields, helping customers establish leading computational capabilities with cost-effective one-stop solutions.
