Network Modernization: TRILOS

Description

The easy-to-transport, high-capacity Terrestrial Transmission Line of Sight (TRILOS) Radio program-of-record improves the expeditionary nature of U.S. Army units, while significantly increasing network throughput and range, operational flexibility and multipath diversity in congested and contested environments.

Packed in a few rapidly deployable transit cases, the small form factor TRILOS Radio provides a significant reduction in size, weight and power (SWaP) compared to the legacy High Capacity Line Of Sight (HCLOS) radio, which needs two sheltered-vehicles, a 5kW generator and two large antennas to relay information. The TRILOS radio increases the robustness of the Army’s tactical network by providing a significant increase in bandwidth and range, with lower latency than satellite communications. The system is also much easier and faster to set up, operate, and maintain.

TRILOS is a dual channel radio and can execute two responsibilities at the same time -- it provides point-to-point communications, but unlike the HCLOS, it will also provide point-to-multipoint communications, enabling Soldiers to shoot multiple shots with one antenna mast, versus needing extra antennas to shoot to multiple terminals. With TRILOS fewer radios, Soldiers and supporting resources are needed.

TRILOS is a key component of the Army’s Capability Set (CS) 21 Expeditionary Signal Battalion-Enhanced network tool suite, which modernizes the Army’s legacy ESBs. TRILOS will also be a key element in the CS 21 Integrated Tactical Network (ITN), providing high capacity terrestrial backhaul transport from the brigade to the enterprise. Other emerging PM Tactical Network radio and cellular capabilities are also expected to be part of the ITN.

TRILOS directly supports and is aligned with the Army Network Modernization Strategy Line Of Effort (LOE) #1 Unified Network; it is fully interoperable with the Army’s Tactical Network architecture, and provides assured high-capacity, range-extending network transport in congested and contested environments against near-peer adversaries. It also supports LOE #4 Command Post Mobility and Survivability, by providing an easy to deploy, quick set up/tear down communications solution to enable units to relocate rapidly, while delivering resilient network transport to ensure the exchange of critical real-time battlefield situational awareness to keep forces safe and ensure mission success.

Capabilities

  •  Adds multipath diversity and operational flexibility to the tactical network
  • Operates in satellite denied environments
  • Significant SWaP reduction over current capability for improved unit agility
  • Significant increase in bandwidth and range versus legacy capability
  • Easy to operate and deploy; requires only two Soldiers for rapid set-up/tear-down
  • Fully interoperable with the Army’s tactical network and architecture
  • Dual channel provides point-to-point and point-to-multipoint communications, enabling Soldiers to shoot multiple shots with one antenna mast, versus needing extra antennas to shoot to multiple terminals
  • Reduces the Army’s reliance on satellites; saves significant costs by reducing the use of expensive commercial satellite airtime leases
