Disadvantaged Users
Across the internet, people enjoy a range of access performance, from low end analog modem connections, to gigabit interfaces. Those with lower performance interfaces generally recognize the limitations of their equipment and take advantage of services that are sized to fit their data handling capacity. Content providers similarly recognize that many users will continue to access their services through low performance connections and offer their services with options to tailor the content to meet the user’s capability. Defense content providers have the same requirement, to make their products accessible to the entire range of connection performance.
THE WAY AHEAD
Current UA communications capabilities must evolve into the future DoD net-centric vision. Current UA support to the war fighter should be sustained while making the transition, but every effort must be made to make the transition as soon as possible. This section outlines practical guidelines to enable the future vision, including a summary of DoD written guidance, the DoD investments intended to produce common hardware and software to facilitate communications mechanisms across UA weapon systems, and the key leadership actions that can be taken right now to realize the net-centric vision soonest. The following summary of direction to the Services and to industry is intended to be the roadmap to guide the UA community’s transition to net-centricity.
DoD Guidance
There is already a body of written DoD direction that must be complied with while designing, building, fielding and sustaining UA systems. OSD publishes policy guidance in the form of Memoranda, Directives, and Instructions. This section provides the major policy statements that address UA communications. It also provides sources for applicable standards. While policy establishes the “what” of the guidance, standards establish the “how,” and support policy with implementation guidelines and technical instructions.
Policy
Policy statements are organized into two groups. The first group directs transformation to a net-centric force that universally operates on the GIG, providing direction for creating the GIG and the mechanisms to enable information to flow freely across it. This includes implementation of interoperable transport

layers (IPv6), deployment of the TCA and transformation of circuit based DISN communications links to IP based services.
Although smaller, the second group provides radio telecommunications guidance that enables wireless connectivity to the GIG and is binding on all UA communications systems and waveforms. While current UA systems support the warfighter through the common data link effort, implementation of common and more flexible physical links with the JTRS program will be the next step. Guidance that implements the GIG consist of:
