IoT Retrofit Solutions – 2G to 4G modem migration

Last Updated on 2025-06-19

4G LTE routers and smart metering modems for 2G migration of your devices

The world of wireless communication, of M2M & IoT have known for years that the obsolete GPRS (2G) networks should be migrated to the state-of-art 4G LTE network worldwide. Thus, the single most important challange nowadays the IoT world has to face: how to migrate the obsolete 2G/GPRS, 3G communication devices to the latest 4G LTE technology. No need to worry though – WM SYSTEMS LLC is there for you! The upgrade of the currently used 2G/3G communication devices to the 4G-level should be performed in the near future. Utility companies and energy providers dispose of a rather tight timeframe for this migration.Our wireless routers and modules represent a future-proof migration solution to the LTE network with the same functionality, on higher data speed.

We offer our 4G devices with migration-platform modules with the same connection and meter manufacturer standards’ compatibility and the usual outfit – with 2G fallback compatibility. (if you still need to use it).
