Application

Application of ndustrial ethernet switch USR-SDR021: Intelligent transportation network transmission

Application

Intelligent transportation network transmission

In the case of intelligent traffic scene, high-definition camera increases the data volume and increases
the pressure of network bandwidth.USR-SDR021 unmanaged industrial ethernet switch supports 100-megabyte rate
to handle heavy traffic through smoothing.It reduce the construction cost.
