Robustel R5020 5G IoT Router

In-vehicle applications
Whether it is passenger WiFi, CCTV debrief, ticketing or a similar “onboard” requirement, the R5020 offers a simple and effective solution.
Broadband Failover
Use Ethernet or Wifi as primary internet and failover to 4G/5G in the event of an outage. IPsec, DMVPN and Open VPN can be used for connections into core networks.
Primary Broadband
Cellular networks can now provide unlimited 5G tariffs at very reasonable prices, offering hundreds of Mbps internet over the air is now commercially favourable.
