Robustel R5020 M2M 5G Router

Robustel R5020 M2M 5G Router

Industrial grade 3G, 4G 5G Router with Ehernet and WiFi and embedded 5G with SIM slot.


Robustel R5020 M2M Industrial 5G Router

The R5020 from Robustel brings next-generation cellular connectivity at a highly competitive price.

Offering global 3G, 4G/LTE & 5G band coverage in a compact industrial form factor, the R5020 enables rapid deployment of high-speed IoT applications in verticals as diverse as Transportation, Enterprise Connectivity, 5G CCTV and Digital Signage.

The R5020 is Robustel’s first 5G-capable router supporting global 5G, 4G and 3G bands.

The Robustel R5020 5G Router leverages the tried-and-tested high performance CPU platform and RobustOS – a mature and stable Operating System developed in-house by Robustel. R5020 is compatible with 3GPP Release 15 and is designed for use by the following applications:


In-vehicle applications: Whether it is passenger wifi, CCTV debrief, ticketing or a similar “onboard” requirement, the R5020 offers a simple and effective solution to increase internet speeds and future-proof current installations. The R5020 has achieved E-Mark certification for in-vehicle use, and supports GNSS positioning. A version with vehicle ignition sensing is available to protect vehicle batteries when the engine is off.

Broadband Failover: The R5020 can be configured to use Ethernet or Wifi as primary internet and failover to 4G/5G in the event of an outage.  This can help to provide resilience to outlets such as shops and small offices at a reasonable cost, and provide sufficient bandwidth for multiple users.  IPSEC, DMVPN and Open VPN protocols 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. For many, a chance to cut the cables and use a wireless internet connection can be technically or commercially favourable.


R5020 5G Router Key Features:

  • Global 5G/4G/3G cellular connections
  • Supports Ethernet, Wifi and 4G/5G internet with auto-failover
  • Very cost-effective industrial 5G router solution
  • Fully programmable Operating System with well documented SDK
  • Multiple VPN options available including DMVPN & IPSEC
  • GNSS, ignition sense & E-mark make R5020 ideal for vehicles
  • Free cloud management platform – RCMS
  • Robust metal enclosure with small footprint – DIN-rail + wall mount options
