CML Micro SCT2400 2.4GHz Digital Voice & Data Transceiver

CML Micro SCT2400 2.4GHz Digital Voice and Data Transceiver operates in the 2.4GHz ISM (Industrial, Scientific, and Medica) band and offers a comprehensive solution supporting near global usage without the need for complex licensing. Capable of replacing unlicensed PMR/LMR solutions (FRS/MURS/GMRS/PMR446), the SCT2400 offers a rich set of features supporting not only secure digital voice operation but also wireless data capabilities.

The SCT2400 also offers a superior operating range over Wi-Fi® based digital radio, providing up to 30dB of additional sensitivity. The range is further extended using voice coding technology with enhanced error correction that maintains voice clarity and a high level of voice security under the most demanding RF environments.

The SCT2400 Transceiver offers extremely low power consumption in both receive and transmit modes, enabling long operating times and the use of small batteries, making it ideal for small form factor and portable applications.
