 *For additional spectrum availability, DoD should recommend that the NTIA, FCC and Department of State should advocate the reallocation of the C-band satellite spectrum to IMT-2000 5G use at the World Radio Conference later this year (WRC-19), and take measures to adopt sharing in all 500 MHz of the band in the United States on an accelerated basis for fixed operations. While this will have limited impact on the U.S. 5G mobile ecosystem, sharing in this band could provide broad coverage at 100 Mbps and above for fixed broadband service to a large section of the rural United States.
 * DoD should encourage other government agencies to incentivize industry to adopt a common 5G network for sub-6 deployment. Incentives can include: accelerated depreciation, tax incentives, low interest loans and government purchase of equipment and services.
 * This recommendation does not call for the eviction of DoD systems operating in the sub-6 GHz spectrum, nor does it call for the sharing of ALL DoD spectrum. DoD must conduct thoughtful but candid analyses of the cost and schedule associated with sharing different spectrum bands, and prioritize accordingly.
 * However, DoD must bear in mind that the status quo of spectrum allocation is unsustainable. 5G capability requires larger bands of spectrum, and without that additional bandwidth, the United States will not gain true 5G capability beyond the limited range that mmWave can provide. In the next year, DoD is in the position to enable or inhibit 5G adoption in the United States based on its use of sub-6 GHz spectrum.
 * DoD stands to significantly benefit if it shares some of its sub-6 GHz spectrum. As the commercial sector develops and deploys 5G technologies and networks, DoD will be able to leverage commercial innovations to build its own new and improved technologies and networks. At a strategic level, 5G can create a step-change in situational awareness and decision-making by integrating more systems into a network that shares more data faster and at lower latency.
 * This effort will require close coordination with NTIA to clear and reassign spectrum. Timing is critical - it is not enough to simply share spectrum, it must be done quickly to keep the United States competitive with China, South Korea, and Japan.
 * Without aggressive action as outlined in this report, we believe there is a high likelihood that the United States will be unable to convince the rest of the world to adopt mmWave technologies as the standard 5G pathway. This may bifurcate the global market and result in the majority of the world adopting 5G sub-6 technologies, which will be dominated by the Chinese equipment and handset manufacturers.

''DoD must prepare to operate in a “post-Western” wireless ecosystem. This plan should include R&D investments towards system security and resiliency on an engineering and strategic level.'' DIB 5G Study
