The SCT2400 operates in the 2.4GHz ISM 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 superior operating range over Wi-Fi based digital radio providing up to 30dB of additional sensitivity. Range is further extended using voice coding technology with enhanced error correction that also maintains voice clarity and a high level of voice security under the most demanding RF environments.

In comparison to other licensed and unlicensed PMR solutions the SCT2400 operates on a fraction of the power in both receive and transmit, enabling significantly longer operating times or the use of smaller batteries that allows innovative small form factor solutions to be realized.

Features

  • Highly integrated 2.4GHz spread spectrum radio transceiver
  • Range optimized vocoder
  • Digital voice modes
    • Peer to peer
    • Group Call
    • Broadcast
  • Data Modes
    • SMS
  • 12.5dBm RF TX power
  • Single 3V supply
  • Low power consumption
    • 10mA standby/scanning
    • 52mA receive voice
    • 64mA transmit voice
  • 144-BGA package (10mm x 10mm)

Applications

  • License Free 2.4GHz Voice + Data
  • Intercoms
  • Access control and gate entry
  • Two-way radio, PMR/LMR
  • Wearable communications
  • Wireless headsets

Range is further extended using voice coding technology with enhanced error correction that also maintains voice clarity and a high level of voice security under the most demanding RF environments. The internal power amplifier achieves 12.5dBm and an operational range up to 2km. Using an external FEM to achieve 100mW output power and -123dBm sensitivity, increases operational range to greater than 12km line of site.
