This new architecture provides for high-bandwidth data service beyond push-to-talk, the major notes. JNN capabilities are significant at the battalion level, where habitual MSE support was lacking. This hub must provide access to the Global Information Grid from its sanctuary location. Douglas points out that the hub is the key to the entire system. The hub would be located in a safe site to serve as the point of presence for Defense Information System Network (DISN) services.

This hub-centric, satellite-based architecture ensures that everyone is just “one satellite hop away from the hub,” he points out.

Bernd Kohler, USA, network engineer in the division’s G-6, explains that the division’s communications architecture comprises two hub nodes, 14 JNNs and 38 command post nodes for a 2/14/38 architecture. Troy Douglas, USA, G-6, network operations, 101st Airborne Division (Air Assault). “We literally have gone from MSE -late-1970s to mid-1980s technology-to the new age of an IP -based world in one jump,” declares Maj. Built by General Dynamics C4 Systems, Scottsdale, Arizona, it is based on commercial off-the-shelf technology, which gives it a greater capability for tying into various other technologies in use. It includes some line-of-sight capabilities for connecting with different levels of forces. These JNNs also are placed with each major division command post, and the division’s four maneuver units of action receive an additional JNN to support their tactical operations centers and their brigades.īecause it relies on satellite linkage, the JNN largely is terrain independent. To provide necessary communications links for these units, each one is equipped with a Joint Network Node (JNN). This transformation eliminated the division’s signal battalion by embedding signal capabilities into each unit of action. The division was one of the first to be reorganized under the units-of-action transformation concept ( SIGNAL, September 2004, page 23). These mobile systems provide connectivity between battalion-level forces and division headquarters, and they tie into a hub that serves as a gateway to the Global Information Grid. Army’s 101st Airborne Division (Air Assault) has incorporated satellite links with a large dose of commercial technology to provide connectivity throughout the battlespace. To get where it wants to go and know what to do when it gets there, the U.S. Redefined forces require a new approach to mobile communications. The 2.4-meter dish system features auto-erect, auto-acquire capabilities that enable users to establish satellite connectivity quickly. At the heart of the 101st Airborne Division (Air Assault) Joint Network Node (JNN) system is its Ku-band satellite communications trailer.
