I think I've only used it for about a month. ■ Features: It utilizes power lines to establish networks in factories, buildings, and other situations where communication line construction or wireless communication is difficult. The multi-hop function allows communication via relays through multiple terminals, enabling the construction of PLC networks even in factories and buildings with long wiring distances. Automatic routing allows communication without troublesome configuration work. ■ Applications: For networking in new communication line construction or situations where wireless communication is difficult. ■ Specifications: Rated Frequency: 50Hz/60Hz Relative Humidity: 30% to 85% (non-condensing) Power Consumption: 4W or less Operating Frequency: 2MHz to 28MHz Communication Speed: 240Mbps Access Method: CSMA/CA Security: AES 128-bit encryption Compliance Standards: HD-PLC method, ITU-T G.9905 Multi-hop Function Maximum Hops: 10 Number of Terminals: Up to 1024
