MDS iNET 900 Transceiver Radio



The MDS iNET Series is an industrial wireless solution that provides long distance, unlicensed communications allowing users to interface with Ethernet and serial controllers. Comprised of the iNET 900 (generic MPN: INET-AP/DG) and iNET-II, the iNET Series offers the best balance of speed and range to enable a wide variety of applications requiring higher data capabilities than typical communication systems can provide. The iNET Series combines the higher speed of Digital Transmission Systems (DTS) with the robustness of Frequency Hopping Spread Spectrum (FHSS) technology.

Key Features:

  • Unlicensed IP/Ethernet and serial data communication
  • High speed, long range point-to-multipoint
  • Prevents unauthorized network access and secures wireless data
  • Reduce configuration and integration costs with a single-box solution
  • Advanced unlicensed interference mitigation algorithms
  • Operation in extreme temperature ranges and hazardous locations
