CRLT.20 - The next generation

Based on its long years’ experience Funkwerk has developed a LTE based cab radio. The CRLT.20 4G cab radio is housed in a standard Double DIN housing and provides telephony and data services. The development followed the relevant railway standards like EN 50128 and the product is designed for use in railway vehicles.
The first SW version provides regular 4G telephony services incl. VoLTE* and IP-based data-services. It can be operated using public available SIM cards.
The development will continue to support upcoming LTE releases and will be adopted to future services like MCPTT (mission critical push to talk) and group communication services.
