CWC U/VHF 110-600

Features

  • Asynchronous receiving of spread spectrum signals, no need for external synchronization systems
  • Transmission via parallel encrypted channels, radically complicates cryptanalysis
  • Data rate 8...11 times faster than similar spread spectrum applications
  • Transmission aligned with the speech codec CELP 2400/4800 (Speex)
  • Simultaneous transmission and broadcast of 8x CELP4800 or 16x CELP2400 voice streams
  • Simultaneous operation with 16x modems, connections schedules are not needed
  • Advanced features of construction/deploying of MESH, Ad-Hoc networks
  • Simultaneous operation up to 16x systems with different encryption keys in the same operational area
  • Access methods:
    • Asynchronous CDMA with different access/encryption keys
    • Synchronous CDMA, CSMA / CD-CDMA access with a single access/encryption key
