Waveforms
JTRS was originally planned to use frequencies from 2 megahertz to 2 gigahertz. The addition of the Soldier Radio Waveform (SRW) waveform means the radios will also use frequencies above 2 GHz. Waveforms that will be supported include:
- Soldier Radio Waveform (SRW)
- Single Channel Ground Air Radio System (SINCGARS) with Enhanced SINCGARS Improvement Program (ESIP), 30-88 MHz, FM, frequency hopping and single frequency
- HAVE QUICK II military aircraft radio, 225-400 MHz, AM, frequency hopping
- UHF SATCOM, 225-400 MHz, MIL-STD-188-181, -182, -183 and -184 protocols
- Mobile User Objective System (MUOS): It is important to note that the JTRS HMS manpack is the only radio program of record that will deliver terminals supporting the next generation UHF TACSAT MUOS program. 85% of all MUOS terminals are expected to be ground radios, so if JTRS HMS fails, MUOS (funded in the billions) fails as well - unless a COTS solution is developed.
- Enhanced Position Location Reporting System (EPLRS), 420-450 MHz spread spectrum
- Wideband Networking Waveform (WNW) (under development)
- Link-4A, -11B, - 16, -22/TADIL tactical data links, 960-1215 MHz+
- VHF-AM civilian Air Traffic Control, 108-137 MHz, 25 (US) and 8.33 (European) kHz channels
- High Frequency (HF) - Independent sideband (ISB) with automatic link establishment (ALE), and HF Air Traffic Control (ATC), 1.5-30 MHz
- VHF/UHF-FM Land Mobile Radio (LMR), low-band 25-54 MHz, mid-band 72-76 MHz, high-band 136-175 MHz, 220-band 216-225 MHz, UHF/T 380-512 MHz, 800-band 764-869 MHz, TV-band 686-960 MHz, includes P25 public safety and homeland defense standard
- civilian marine VHF-FM radio, 156 MHz band
- Second generation Anti-jam Tactical UHF Radio for NATO (SATURN), 225-400 MHz PSK Anti-jam
- Identification Friend or Foe (IFF), includes Mark X & XII/A with Selective Identification Feature (SIF) and Air Traffic Control Radar Beacon System (ATCRBS), Airborne Collision Avoidance System (ACAS) and Traffic Alert & Collision Avoidance System (TCAS), and Automatic Dependent Surveillance – Addressable (ADS-A) and Broadcast (ADS-B) functionality, 1030 & 1090 MHz
- Digital Wideband Transmission System (DWTS) Shipboard system for high capacity secure & nonsecure, line-of-sight (LOS), ship-to-ship, and ship-to-shore, 1350-1850 MHz
- Soldier Radio & Wireless Local Area Network (WLAN), 1.755-1.850, 2.450-2.483.5 GHz, Army Land Warrior program 802.11
- Cellular telephone & PCS, includes multiple US and overseas standards and NSA/NIST Type 1 through 4 COMSEC (SCIP)
- Mobile Satellite Service (MSS), includes both VHF and UHF MSS bands and both fielded and emerging low Earth orbit and medium Earth orbit systems and standards, such as Iridium, Globalstar, et al. Includes capability for NSA/NIST Type 1 through 4 COMSEC, 1.61-2 GHz. May allow use of geosynchronous satellites with special antenna.
- Integrated Broadcast Service Module (IBS-M). Currently three legacies UHF military broadcasts (TIBS, TDDS, and TRIXS) which will be replaced in the future with a Common Interactive Broadcast (CIB).
- BOWMAN, the UK Tri-Service HF, VHF and UHF tactical communications system.
Several of the above waveforms will not be supported in JTRS Increment 1 and have been deferred to "later increments". Currently, only Increment 1 is funded. The requirements document for JTRS Increment 2 is under development. JTRS Increment 1 threshold waveforms include:
