Product Overview
The Teltonika RUTM521 (RUTM52 platform) is an industrial cellular router featuring two 5G Sub-6 modems for high throughput and always-on connectivity. It supports 5G SA and NSA and is backwards compatible with 4G LTE Cat 20 as well as 3G. With dual SIM plus eSIM and flexible switching/backup scenarios, it is well suited for mission-critical sites, remote infrastructure and complex network deployments.
