PLBus high-speed carrier main module

Features
LM3460DE-T01J-H01M type PLBus high-speed carrier module can provide users with high-speed data transmission services based on power line communication. As the master node in the hPLBus network, this module is responsible for network management and network maintenance. It can be embedded in various routers, gateways, concentrators and other management equipment, and is widely used in various IoT applications within a distance of tens of meters to hundreds of meters. Scenes.



Main features of the product
 ● Data transmission is carried out through the power supply line, no wiring is required, and the wall becomes more and more bizarre.
 ● Ms-level communication delay and fast response speed.
 ● Support multiple application scenarios of point-to-point, 1-point-to-multipoint, and multi-point-to-one point.
 ● No networking time, just install and use.
 ● High performance, in the standard test environment, the highest anti-attenuation ability can reach more than 100dB, which can meet various complex application scenarios.
 ● Built-in complete protocol stack, including physical layer, data link layer (MAC sublayer and network sublayer) and application adaptation layer, to provide customers with network communication services, data interface communication services and secondary development library support.
