Whilst not a plug and go solution, they are designed to be integrated into a host device, for instance for transfer of GNSS correction data in a land surveying rover or RTK base station. SATELLINE-M3-TR4 are UHF data transceiver modules in a lightweight single PCB structure. 

SATELLINE-M3-TR4 is equipped with all necessary features; such as 70 MHz tuning range (403...473 MHz) in one hardware, selectable channel width, AES128-bit encryption available for secure transmission and low power consumption. 1W output power in conjunction with a very sensitive receiver are the guarantee of a reliable data connection. 

The configuration of the radio module can be made by using the SATEL SL-commands or SATEL Configuration Manager -software. 

SATELLINE-M3-TR4 is compatible with widely used SATELLINE-3AS and -EASy radio modems and also with other manufacturers’ radio protocols. 

The M3-TR4 will give you the option of TWICE the speed of the older TR3 and additional modulation options!

For an 869MHz version there is now the M3 TR8
