WIN-T Increment 1
Warfighter Information Network-Tactical (WIN-T) is the Army's current and future tactical communications network backbone that provides seamless, assured, communications for the Soldier along with advanced network management tools to support implementation of a commander's intent and priorities – incrementally. WIN-T Increment 1 establishes a network backbone that provides the full range of data, voice and video communications to battalion and above echelons using satellite communications nodes that set up at-the-quick-halt to successfully meet operational requirements.
The Army began fielding WIN-T Increment 1, formerly known as the “Joint Network Node Network,” in 2004 and completed fielding in 2012. Similar to a home Internet connection, WIN-T Increment 1 provides a full range of at-the-halt data, voice and video communications, allowing Soldiers to simply pull over on the side of the road to communicate without setting up complicated infrastructure. WIN-T Increment 1 provides this networking capability to command posts and units at the battalion level and above. A follow-on enhanced networking upgrade, referred to as the “WIN-T Increment 1B upgrade,” is underway to improve the efficiency, security and interoperability of the network. The WIN-T Increment 1B upgrade provides the Colorless Core, which enhances network security and interoperability with future WIN-T Increments, and takes advantage of the Network Centric Waveform (a dynamic waveform that optimizes bandwidth and satellite utilization).
- WIN-T Increment 1 has three types of transportable network nodes that provide high-speed wide area network capability for secure voice, video and data exchange. The Tactical Hub Node (THN) supports division headquarters; the Joint Network Node (JNN) supports brigade level headquarters; and the Battalion Command Post Node (BnCPN) supports battalion level headquarters. The fourth type of node, the Regional Hub Node (RHN), is a fixed installation equivalent to three THNs and is used to support theater level operations.
- The Satellite Transportable Terminal (STT) is highly transportable and mobile satellite system, which operates in conjunction with the JNN and BnCPN, designed to establish secure voice, video and data communications virtually anytime and anywhere.
