Enabling the exchange of information across the battlefield, Warfighter Information Network-Tactical (WIN-T) Increment 1 positions commanders and Soldiers to meet the Army's full spectrum operations.
Fielded to 76 percent of the total force, WIN-T Increment 1 is a communications network that allows Soldiers to communicate at-the-halt in any terrain. The system provides high-speed, high-capacity voice, data, and video communications, similar to a home internet connection, to allow information exchanges from any source to be relayed successfully to other units. It leverages commercial satellite technology to provide beyond line of sight capabilities and commercial networking technology to increase functionality and efficiency while reducing size, weight and power.
WIN-T Increment 1 establishes a network backbone that provides the full range of audio and visual communications to various echelons and locations using satellite communications nodes that can be coupled with High-Capacity Line-Of-Sight (HCLOS) radio communications and set up at-the-quick-halt to successfully meet the requirements needed in theater.
WIN-T Increment 1, the former Joint Network Node program, was developed as an immediate response to the need for beyond-line-of-sight communications in 2001's Operation Enduring Freedom in Afghanistan and 2003's Operation Iraqi Freedom. The 3rd Infantry Division was the first deployed into theater with this new capability.
WIN-T Increment 1 is actually subdivided into 1a and 1b. Increment 1a is the JNN system as it now exists, but with the added capability of communicating via Ka-band military satellites as well as the commercial Ku-band satellites. (Ka and Ku refer to sections of the electromagnetic spectrum). Utilizing Ka-band Department of Defense Wideband Global SATCOM satellites (WGS), reduces reliance on commercial Ku-band satellites, offering greater efficiency and cost effectiveness.
Increment 1b will add a Network-Centric Waveform (NCW) modem and a colorless core enclave to the existing design. This technology insertion will enable single-hop satellite connectivity to WIN-T Increment 2 units and other On-The-Move (OTM) platforms using NCW. These enhancements are essential since Increment 1b will remain in Army's force structure even as future WIN-T Increments becomes available. Increment 1b is to be used by support units and in rear areas in which OTM communicating is not required.
While WIN-T Increment 1 provides satellite communications at the quick halt to the battalion level and above, Increment 2 will bring the initial on the move capability down to the company level. WIN-T Increment 2's OTM capability will increase speed of maneuver on the battlefield and allow Soldiers and commanders to stay connected at all times.
PM WIN-T is assigned to the Program Executive Office of Command, Control, Communications-Tactical, which continues to develop, field and support networked battle command solutions to meet the evolving operational requirements of deployed forces.
