Power Line Communication for Seamless Networking

The Digital Power Line device uses Power Line Communication technology by superimposing data signals onto existing electrical wiring. This method allows power and data to travel simultaneously along the same lines, transforming the power grid into a dual-purpose network. By applying this principle, the device enables rapid networking throughout the entire electrical infrastructure without requiring extra cabling, making data transmission simpler, faster, and more efficient.

Redefining High-Bandwidth Network Coverage with Power Line Communication

Our broadband power line communication device uses advanced OFDM technology to deliver data rates up to 10 Mbps across the 2–28 MHz band. That's 8 to 12 times faster than traditional narrowband systems, providing a robust, high-bandwidth networking foundation for next-generation industrial applications like flexible production line control, ultra-high-definition media transmission, and AR-powered remote collaboration.

Seamless High-Speed Communication with Robust Security

Our device ensures reliable and secure data transfer with advanced LDPC error correction and AES-128 encryption. It features full transparent data forwarding and smart routing algorithms, enabling automatic network formation and flexible adaptation to complex bus and star topologies. This makes it perfect for demanding industrial environments.

Robust Long-Distance Transmission for Comprehensive Network Coverage

Leveraging advanced power line communication, the device supports point-to-point transmission up to 500 meters. It provides wide coverage across complex environments such as buildings, industrial facilities, and underground spaces, ensuring stable long-distance networking without the need for repeaters. This greatly reduces deployment and maintenance costs.
