R1520 industrial 4G VPN router buying guide
Best for
Industrial LTE deployments that need secure VPN access, serial or Ethernet connectivity, reliable remote monitoring, and a cost-effective alternative to 5G.
Not ideal for
Applications that require 5G-level throughput, heavy video backhaul, or local edge computing workloads that should run on a gateway platform.
Key specs to check
Confirm regional LTE bands, Ethernet and serial ports, VPN requirements, I/O needs, dual SIM failover, mounting, power input range, RobustOS functions, and RCMS use.
Typical deployments
SCADA/PLC connectivity, utility sites, remote machines, kiosks, industrial automation networks, backup WAN, and fleet-managed LTE router rollouts.
