WIN-T Increment 1: Sig Mod


Current and future military operations require reliable communications capabilities that can be rapidly deployed anywhere in the world. The Signal Modernization (Sig Mod) program aims to increase the expeditionary nature of today’s forces and their ability to deploy the right size units to the right place at the right time. Sig Mod will provide expanded network transport capacity to WIN-T Increment 1 and Increment 2 while reducing the tactical signal support footprint and strategic lift requirements for operational brigades, divisions, corps and expeditionary signal battalions (ESBs). It increases the agility, scalability and the expeditionary nature of units.

Sig Mod will transform and augment the Army's communication capabilities and extend the network to lower echelons via modular, scalable and interoperable nodes. Operational requirements have pushed the need for communication capabilities lower in Army formations. The new network enhancements will provide significant increases in throughput and situational awareness, further untether commanders from the command post and enable a more rapidly deployable force by reducing size, weight and power (SWaP). The Sig Mod program improves provides continued communications to the tactical edge.

Main Components

  • Enroute Mission Command Capability (EMC2) will provide military internet access and mission command capability for Soldiers while in flight on US Air Force C-17s to support rapidly deployed joint Global Response Force (GRF) missions. EMC2 enables GRF units to plan and maintain critical situational awareness in the air, keeping joint forces connected as they travel into developing situations.
  • A new Wi-Fi and 4G LTE Cellular transmission infrastructure capability will support Soldier wireless and cellular handheld requirements from Command Posts (CPs) to the edge of the tactical formation.  CP Wi-Fi covers a limited footprint and is used inside the ‘skin’ of the tent, while 4G LTE is used with smartphones and eventually tablets to extend coverage to an entire base radius.
  • TRILOS, a new high bandwidth WIN-T interoperable network radio, establishes a terrestrial link for a more robust network. It also reduces SWaP and significantly increases throughput.
  • A transit-cased Troposcatter transmission (Tropo) system provides increased data throughput, reduced manning, and decreased SWaP. Tropo systems shoot microwaves that bounce off of the troposphere layer of the atmosphere instead of a satellite, allowing for secure, high-speed transfer of large volumes of data between sites and over terrestrial obstructions such as mountains. They also reduce the Army’s reliance on expensive commercial and military satellites.
  • The Commercial Coalition Equipment (CCE) can be rapidly reconfigured to provide secure tactical access for one of four different networks: the coalition network, Secure Internet Protocol Router (SIPR), Non-secure Internet Protocol Router (NIPR), or commercial internet and phone service.
  • An integrated radio-bridging and voice cross-banding module allows interconnection between telephones, combat net radios, first responders’ radios and voice applications supporting both civil and military operations. It enables seamless interoperability among disparate radio networks without supplying common radios to these users.
  • A new network stack, the Modular Communications Node - Advanced Enclave (MCN-AE), enables intelligence users to connect into the WIN-T network.
