Editing Joint Tactical Radio System (section)

==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&nbsp;GHz. Waveforms that were to be supported included:

* [[Soldier Radio Waveform]] (SRW) {{Dead link|date=March 2018}}
* Single Channel Ground Air Radio System ([[SINCGARS]]) with Enhanced SINCGARS Improvement Program (ESIP), 30-88&nbsp;MHz, [[FM broadcasting|FM]], [[frequency hopping]] and single frequency
* [[HAVE QUICK]] II military aircraft radio, 225-400&nbsp;MHz, [[Amplitude modulation|AM]], frequency hopping
* UHF SATCOM,  225-400&nbsp;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. This is only true from the Army viewpoint, other services also use MUOS, not related to JTRS. 
* [[Enhanced Position Location Reporting System]] (EPLRS), 420-450&nbsp;MHz [[spread spectrum]]
* [[Wideband Networking Waveform]] (WNW) (under development)
* Link-4A, -11B, - [[Link 16|16]], -22/TADIL tactical data links, 960-1215&nbsp;MHz+
* VHF-AM civilian [[Air Traffic Control]], 108-137&nbsp;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&nbsp;MHz
* VHF/UHF-FM Land Mobile Radio (LMR), low-band 25-54&nbsp;MHz, mid-band 72-76&nbsp;MHz, high-band 136-175&nbsp;MHz, 220-band 216-225&nbsp;MHz, UHF/T 380-512&nbsp;MHz, 800-band 764-869&nbsp;MHz, TV-band 686-960&nbsp;MHz, includes [[Project 25|P25]] public safety and homeland defense standard
* civilian [[Marine VHF radio|marine VHF-FM radio]], 156&nbsp;MHz band
* Second generation Anti-jam Tactical UHF Radio for [[NATO]]  (SATURN), 225-400&nbsp;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 ([[Automatic Dependent Surveillance-Broadcast|ADS-B]]) functionality, 1030 & 1090&nbsp;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&nbsp;MHz
* Soldier Radio &  Wireless Local Area Network (WLAN), 1.755-1.850, 2.450-2.483.5&nbsp;GHz,  Army Land Warrior program [[802.11]]
* [[Cellular telephone]] & PCS, includes multiple US and overseas standards and [[NSA]]/[[NIST]] [[Type 1 product|Type 1]] through 4 [[COMSEC]] ([[Secure Communications Interoperability Protocol|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 Satellite LLC|Iridium]],  [[Globalstar]], et al.  Includes capability for NSA/NIST Type 1  through 4 COMSEC, 1.61-2 [2.5]  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 (communications system)|BOWMAN]], the [[United Kingdom|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:
