Robustel R5020L-A-5G-A25GL - High Speed Smart 5G Router 2x Eth 1x RS232/RS485 dual-band WiFi (B098004)
Features
The R5020 Lite is Robustel's new 5G capable router supporting global 5G, 4G and 3G bands. The R5020 Lite leverages the tried and tested high performance CPU platform and RobustOS 5 - an Operating System developed in-house by Robustel that has passed extensive 3rd party penetration testing.
- Low cost industrial 5G Router
- Global 5G/4G/3G cellular connections
- Cutting-edge 5G 3GPP Release 16 cellular interface
- Supports Ethernet, Wi-Fi and 5G/4G internet with auto-failover
- 1 x RS232/RS485 (software configurable) ports for connection to industrial/legacy devices
- Fully programmable Operating System with well documented SDK
- Multiple VPN options are available, including DMVPN, IPsec, L2TP + more…
- Free cloud management platform - RCMS
- Robust metal enclosure with small footprint - DIN-rail + wall mount options
R5020 Lite is compatible with 3GPP Release 16 and targeted at the following applications:
Broadband Failover
R5020 Lite can be configured to use Ethernet or Wi-Fi as primary internet and failover to 5G/4G in the event of an outage. This can help provide resilience to shops and small offices at a reasonable cost and provide sufficient bandwidth for many users. IPsec, DMVPN, GRE+ many more protocols can be used for connections into core networks.
Primary Broadband
Cellular network operators can now provide unlimited 5G tariffs at very reasonable prices. For many, a chance to cut the cables and use a wireless internet connection can be technically or commercially favorable.
SD-WAN
Whilst many appliances have cellular options built-in, the R5020 Lite can offer a very low-cost way to add a 5G backup route & by virtue of being able to located externally to the appliance, is more likely to get a good 5G signal!
Application Example

R5020-Lite Use Cases
In-Vehicle Connectivity
Provide secure 5G backhaul for emergency services and fleets with in-vehicle computers, cameras, and location reporting via GNSS; manage updates and diagnostics centrally with RCMS.

SD-WAN 5G Backup
Add a cost-effective 5G backup path to SD-WAN appliances; external mounting improves signal; central monitoring and updates reduce the risk and cost of truck rolls.

High-Speed Industrial IoT
Add high-bandwidth 5G backhaul for robotics, video, telemetry, and data-heavy workflows at plants and yards. Reduce rollout time versus fibre; manage security and updates at scale.
