Along with written guidance above, the DoD has invested in common products with the expectation that
they be used to a maximum extent possible. This is to correct the weakness from past experience where
each developing UA would invest in its own unique communication mechanism or design a system
architecture that drove unique communication solutions. While the capabilities and schedules of these
common-use programs may change, the following represents the best knowledge as of the time of this
writing. UA programs should seek to synchronize their systems with the milestones of the applicable
programs: CDL, JTRS, TSAT, FAB-T and HAIPE.
In the area of net-centricity, GIG capabilities will not come on line simultaneously but will ramp up in a
series of spirals. Once fielded, these capabilities will continue their evolution. Figure C-9 illustrates the
spiral approach to achieving the net-centric force. Spiral 1, 2006, connects UA to the net and bridges
gaps between legacy systems resulting from nonstandard data structures and transport mechanisms.
Transition to IP based transport and metadata registration constitutes foundation elements to this strategy.
Spiral 1 also introduces JTRS in a move toward a more flexible, interoperable system of software defined
tactical radios and dynamic wireless networks. Spiral 2, 2008, leverages advances in net-centric

communications, providing more robust connectivity between nodes and more efficient use of all
available bandwidth. In Spiral 2, UA become an integral part of the net, with their excess bandwidth
being made available to the GIG, improving the overall flow of data. Spiral 3, 2012, introduces the TSAT
and its space born network of optical and RF receiver/transmitters and routers. It also adds new
broadband connectivity between SATCOM and UA through the insertion of optical (laser) data link
technology. Teleports connecting the SATCOM constellation to the GIG-BE fiber backbone complete
the circuit and provide truly global communications. By spiral 4, 2016, the GIG has become the
envisioned ubiquitous network, providing information on demand to warriors on the move, transparently
and seamlessly.

CDL
While the future of wide band data links (>274 Mbit/s) is unclear, it will certainly involve a JTRS/SCA
compliant solution. Two potential directions are evident at this time, either an enhancement to the WNW,
or an SCA compliant iteration of the CDL managed under the auspices of the JTRS program office.
Regardless, the final solution will become part of the JTRS set of software defined radios.
