ModemOS is a 2SIM GSM/UHF * modem with Steady Stream technology. Unlike most modems, automatically switching between SIM cards depends on the stability of receiving the correction stream. Parameters like signal/noise ratio and status of Internet connection don't influence on switching.

The built-in 2 W UHF modem* allows you to use ModemOS as a common radio modem.

Intelligent selection of the most reliable correction stream between GSM1, GSM2 and UHF - ModemOS automatically switches the type of communication depending on the availability or absence of the UHF or GSM signals.

You can create the list of GNSS base stations with UHF transceivers with appropriate coordinates and UHF parameters. Thanks to the built-in GPS/GLONASS receiver, ModemOS automatically detects the nearest UHF translator and connects to it.
