Joint Tactical Radio System 2C

The Joint Tactical Radio System (JTRS) 2C is a programmable, wideband, secure, open architecture communications system. It provides virtual circuit and datagram service, which guarantees reliable, simultaneous, multichannel voice, data, imagery, and video transmission.

The JTRS core modules can be configured for ground, shipboard, and airborne platforms. Digital signal processing provides flexibility and operational simplicity in end-to-end communication connectivity, packet formatting, and packet switching protocols. Spread spectrum modulation provides low probability of intercept/anti-jam (LPI/AJ), transmit power controls (LPD), and embedded encryption. This ensures the security and integrity necessary in today's strategic and tactical networks. The basic JTRS 2C radio system provides coverage from 225 to 400 MHz; however, 2 MHz to 2 GHz frequency range, based on the JTRS 2A solution, can be provided in the near term.

JTRS 2C Features:

  • Two simultaneous independent channels, additional channels available in near term
  • 225 - 400 MHz frequency range, 2 MHz to 2 GHz available in near term
  • LPI and AJ _ DSSS and FH
  • Adaptive power control
  • Embedded Type 1 encryption
  • JTRS SCA-compliant
    • Reprogrammable and reconfigurable
    • Architecture supports all JTRS ORD compliant waveforms
  • 20 watts per channel power out
  • Two networking waveforms - self-forming and self-healing
    • CSMA - 400 nodes
    • TDMA - 16 nodes
  • JTA-compliant information exchange interfaces
    • PPP
    • SNMP
    • IP routing

JTRS 2C Application:

  • The JTRS provides wireless local area network (LAN) service for both line-of-sight and beyond-line-of-sight data and/or voice links.

  • Adaptive routing provides for network survivability in the most challenging of dynamic mobile subscriber applications, as required by the TOC-to-TOC tactical internet/warfighter information network (WIN) Architecture.

  • With near-term upgrades, our JTRS architecture supports all waveforms in the ORD and will meet many other tactical communications requirements.
