ROBUSTEL R5020L-A-5G-A25GL INTRODUCTION
The R5020 Lite is Robustel’s new 5G capable router that supports 5G, 4G, and 3G Networks. The R5020 Lite 5G Router Series leverages our tried and tested high-performance CPU platform and
RobustOS 5 – an Operating System developed in-house by Robustel that has passed
extensive 3
rd party penetration testing. 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+, and many more protocols can
be used for connections to 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.
