The DoD’s formal Private 5G Deployment Strategy, signed in October 2024 and publicly released in November, marked a significant shift in military communications. Instead of relying on a single technology, the strategy positions 5G as one element within a broader hybrid ecosystem that also includes commercial cellular networks, tactical radios, and satellite communications. This strategic direction recognizes that resilience comes from diversity across multiple paths.
For military drones operating in non-line-of-sight (NLOS) conditions, this hybrid approach is essential. Yet without intelligent connectivity layers that seamlessly transition between networks, the DoD’s vision remains a set of robust but isolated systems that can’t work in concert when missions demand it most.

Understanding DoD’s Hybrid 5G Strategy
The Department of Defense (DoD) has embraced a new approach to military communications. Rather than building a single, monolithic network, the DoD’s strategy positions private 5G as one essential element within a broader, multi-domain communications architecture. This approach recognizes that no single technology can deliver connectivity everywhere, under all conditions. Strategic resilience requires diversity.
DoD anticipates that most installations will primarily use commercial 5G, with private 5G “under certain circumstances.” Using dedicated spectrum allocations, including CBRS (Citizens Broadband Radio Service) bands and military-specific frequencies, private 5G networks offer strong security controls, full bandwidth ownership, sub-10-millisecond latency, and guaranteed priority access. For military drones, these capabilities enable high-definition ISR streaming and precise coordination for manned–unmanned teaming.
The DoD’s approach is pragmatic: use the best available network for each operational context, embracing commercial 5G integration where it makes sense. In CONUS (Continental United States) training environments or allied territories with robust commercial networks, leveraging existing cellular infrastructure enables rapid deployment and reduces costs.
Tactical network integration completes the picture. Legacy MANET (Mobile Ad hoc Network) mesh radios, tactical RF systems, and SATCOM links must interoperate seamlessly with both private and commercial 5G networks. The strategy looks at future technologies like LEO satellite constellations and emerging 6G standards, ensuring today’s investments remain relevant for tomorrow’s capabilities.
This hybrid vision creates both opportunities and challenges for military drones as uncrewed systems must maintain continuous connectivity as they move across multiple networks.
The Private 5G Advantage for Military Drones
Private military 5G networks deliver high bandwidth 4K ISR streaming, revealing tactical details impossible to discern at lower resolutions. Real-time data transmission enables onboard AI and machine learning processing, allowing drones to identify targets, classify threats, and analyze terrain autonomously.
With a latency of a few to tens of milliseconds, drones can execute precision maneuvers and respond to threats instantly, preserving meaningful human control over weapon systems while leveraging AI speed.
The secure architecture of private 5G provides end-to-end encryption on dedicated infrastructure, network slicing that isolates mission-specific traffic, and complete control over access points to reduce vulnerability.
Operationally, private 5G offers unprecedented flexibility. Rapidly deployable “5G in a box” systems can establish secure, high-performance networks at expeditionary locations, eliminating dependency on host-nation infrastructure that may be unreliable or compromised. Systems scale from small forward operating bases to major installations, adapting to mission requirements.
Spectrum-aware communications delivers substantial advantages. Prioritizing access eliminates the congestion that plagues commercial networks during crises, when everyone simultaneously seeks connectivity. Dedicated bandwidth ensures mission-critical drone operations never compete with non-essential traffic, and Quality of Service guarantees mean commanders can rely on consistent performance.
The Integration Challenge
Different networks rely on distinct communication protocols, authentication methods, and encryption standards. These differences create significant handoff complexity at the boundaries between commercial, private, tactical, and satellite systems. Security requirements also diverge sharply. Open commercial networks follow public standards, while classified military environments require strict access and security controls.
These technical barriers create operational gaps. Traditional systems treat networks as mutually exclusive rather than complementary resources to be used simultaneously. Each network transition occurs as a discrete event: disconnect from the current network, authenticate to another network, rebuild the command link, and resume operations. During these moments, the drone must rely on autonomy or suspend certain functions. Video feeds freeze, telemetry delays increase, and control inputs accumulate instead of executing in real time. Transitions are often the most vulnerable moments in contested environments. Jamming, spoofing, or spectrum congestion can disrupt authentication or prevent re-establishment of the link altogether, leaving the drone without reliable C2.
Elsight’s Halo platform uses simultaneous multilink connectivity and smarter mobility management to mitigate these issues.
Elsight’s Halo Multilink NLOS Connectivity for Hybrid Network Operation
Elsight’s Halo NLOS communication module transforms the DoD’s hybrid network vision into an operational reality. Elsight’s Halo multilink bonding technology aggregates every available network, private 5G.MIL, commercial 5G, and LTE, MANET tactical radios, and SATCOM links into a logical connectivity layer of spectrum, which is transparent to operators and applications. Continuous monitoring and predictive analytics detect and address weak links before performance is impacted, and seamless handoffs instantly reroute traffic to the most reliable channels, ensuring continuous NLOS operations across networks.
All mission-critical data, C2, video, telemetry, and sensor feeds are automatically fragmented into AES-256-CBC encrypted packets, preserving security across private and public networks.
The sub-100-gram form factor matches the requirements for small tactical drones and mobile robotics, making this capability accessible across the full spectrum of uncrewed platforms.
Proven in real-world combat operations across multiple world conflicts, Halo delivers the connection confidence that defense integrators demand. Leading manufacturers like Lockheed Martin have already embedded the Halo NLOS connectivity module to guarantee seamless command and control (C2) and high-bandwidth intelligence, surveillance, and reconnaissance (ISR) performance in their uncrewed platforms.
The future battlespace will rely on hybrid networks that blend private and public 5G, tactical systems, satellite links, and resilient multi-path technologies to ensure continuous C2 and data flow. As forces adopt distributed, flexible communication architectures, mission success will depend on adaptable and secure connectivity. Multilink bonding transforms multiple fragmented networks into a unified communication fabric where the whole becomes greater than the sum of its parts.
