The Key to Reliable Military Comms

Reading time: 12 minutes

Modern military operations demand high-performance communication systems that deliver continuous connectivity and real-time situational awareness. As missions grow more complex and extend across vast, contested environments, maintaining reliable beyond visual line of sight (BVLOS) communications is no longer optional, it’s essential. Today’s military forces require communication systems that can adapt, persist, and perform reliably in the most challenging contested environment.

Uncrewed aerial vehicles (UAVs) support multiple military missions such as electronic warfare, surveillance, target acquisition, precision strikes, combat search and rescue, logistics, etc. To execute these missions successfully, UAVs must maintain uninterrupted connectivity for control and for continuous data transmission over long distances. Leveraging a broader radio spectrum across commercial, private, and tactical links transforms military comms and enables a new era of secure, flexible NLOS operations.

In this blog post, we’ll delve into the limitations of conventional military communications in contrast to using all available spectrum for optimal connectivity offered by advanced NLOS communication systems.

The Challenges of Traditional Military Communication Solutions in Modern Warfare

Legacy military radio communication systems were designed for different operational environments and threat landscapes. These systems typically relied on dedicated, often proprietary frequency bands and point-to-point, line-of-sight radio links.

While these solutions work well in conventional warfare scenarios, they struggle to meet the demands of modern battlefield operations. It’s particularly problematic when operating unmanned systems at extended distances. Relying on dedicated frequency bands for UAV connectivity exposes operations to several key risks:

• Spectrum congestion: Military frequencies can become congested, especially during large-scale operations involving numerous assets. This congestion can lead to reduced bandwidth, increased latency, and communication failures.
• Susceptibility to jamming: Reliance on specific frequency bands makes these systems vulnerable to electronic warfare attacks.
• Deployment complexity: Dedicated military communication radio networks can be complex and costly to deploy and maintain, particularly in remote or rapidly evolving operational threats. This infrastructure may also lack the flexibility and scalability to adapt to dynamic and portable mission requirements.

Why Modern Battlefields Require Full-Spectrum Radio Communications

Today’s operational environment demands a fundamental shift in how military forces approach spectrum utilization. The modern battlefield is characterized by distributed operations, multi-domain warfare, unmanned vehicles, and sophisticated electronic warfare threats that require adaptive, resilient communication strategies.

Commercial wireless infrastructure has expanded dramatically over the past decade, creating a vast network of cellular towers, satellites, and other communication assets that cover previously unreachable areas. This infrastructure represents an untapped resource for military operations, providing unparalleled coverage.

The proliferation of 5G networks has further expanded available bandwidth and reduced latency, creating new opportunities for military applications. These networks offer enhanced capabilities for real-time video transmission, low-latency command and control, and high-bandwidth data transfer that can significantly improve UAV performance and mission effectiveness.

Software-defined radio (SDR) technology enabled the dynamic utilization of diverse frequency bands. Satellite communication options have also diversified, with new Low-Earth Orbit (LEO) constellations providing global coverage with reduced latency compared to traditional geostationary satellites. These systems offer additional pathways for non-line-of-sight communications that complement terrestrial networks.

Introduction to Full Spectrum Connectivity

For today’s military communications, it is critical to maintain spectrum superiority and secured Beyond Visual Line of Sight (BVLOS) communications. You can achieve this by using a solution that  aggregates all available communication links, including LTE/5G, SATCOM, and P2P/MANET into a single data pipeline. This capability ensures uninterrupted connectivity for mobile SOF (Special Operations Forces) and their unmanned platforms by removing reliance on any one network, enhancing operational effectiveness in contested, GPS-/comms-denied, and expeditionary environments.

By using intelligent bonding technology, the data is split into AES-256-CBC encrypted packets and transmits them simultaneously across all available networks. These packets are reassembled at the destination through secure VPN tunneling, maintaining both security and redundancy. The system automatically routes traffic based on real-time link performance and provides seamless transitions between networks without drops by using a logical connectivity layer.

Other important considerations include having a compact size and a wide range temperature compatibility, remote management, predictive analytics, and 3D network coverage tools.

In contested environments, adversaries actively work to disrupt military communication radio systems through electronic warfare tactics. Spectrum-aware connectivity counters these threats by simultaneously distributing communications across multiple frequency bands, carriers, and transmission methods. This approach ensures that mission-critical communications can continue through alternative pathways even if portions of the spectrum are compromised or unavailable.

The concept extends beyond simply using multiple frequencies. It encompasses intelligent sensing and routing, dynamic spectrum allocation, and real-time adaptation to changing electromagnetic conditions.

Spectrum-aware connectivity ensures robust and redundant BVLOS communications in remote or jammed environments. It also allows militaries to take advantage of commercial network infrastructure, extending range, increasing flexibility, and reducing dependency on legacy systems.

UAV NLOS operations must use every available communication channel to gain greater reach, reliability, and resilience. The shift towards leveraging a broader radio spectrum offers several key advantages for military comms, particularly for NLOS UAV operations.

Communication becomes significantly more resilient to jamming and interference by operating across multiple frequency bands. If one band is compromised, the system can seamlessly switch to another available frequency, allowing UAVs to adapt to changing electromagnetic environments and avoid congested or contested frequencies.

Furthermore, accessing a wider range of frequencies significantly increases the available bandwidth, allowing for the transmission of larger data volumes, higher-resolution video feeds, and more complex command and control signals.

 Cellular networks can add resilience to battlefield connectivity

The rapid pace of commercial technology development offers military UAVs access to the latest communication capabilities without lengthy procurement cycles. Integrating commercial networks, such as cellular networks and Satcom, into military communication strategies offers numerous tactical and strategic advantages that can significantly enhance operational effectiveness while reducing costs and complexity.

• Wide availability and coverage: Commercial networks provide extensive coverage, particularly beneficial for BVLOS (beyond line-of-sight) operations over long distances.
• High bandwidth and data rates: LTE and 5G networks offer high bandwidth and low latency, enabling the transmission of high-definition video, large sensor data sets, and C2 information.
• Cost-effectiveness: Utilizing commercial networks reduces the cost of developing, deploying, and maintaining dedicated military communication infrastructure. This approach lowers acquisition costs, operational expenses, and logistical burdens while providing access to cutting-edge technology.
• Redundancy and resilience: Multiple carriers and distributed infrastructure create a communication environment that can survive partial network failures or targeted attacks while maintaining connectivity.
• Rapid deployment: Commercial network infrastructure is already in place, allowing for fast deployment and integration of UAV communication capabilities.

A robust solution must intelligently integrate commercial networks with other communication methods, such as private networks, satellite communications, and Software Defined Radios (SDRs), within a secure and resilient framework.

Adding a Logical Connectivity Layer

Implementing a sophisticated logical connectivity layer is crucial to effectively harness the power of the full radio spectrum and to mitigate the inherent risks of relying on a single communication link. This layer acts as an intelligent intermediary, abstracting the underlying physical communication links and providing the UAV operator with a unified and seamless communication experience.

A communication system logical connectivity layer is a sophisticated software-driven intermediary that abstracts the complexity of multiple underlying physical communication links (like cellular, satellite, and other radio frequency connections).

The NLOS platform should bond all available spectrum, including 5G/LTE, MANET/RF, private networks, and SATCOM, into a single, intelligent tunnel. It should continuously steer traffic to the healthiest paths, eliminating single points of failure and acting as the “air‑traffic controller” at the packet level and in milliseconds. This logical layer continuously monitors the performance and availability of all connected networks, including cellular carriers, satellite links, and radio frequency connections bonding them together to ensure connectivity.

To orchestrate this complex network of communication options, this logical layer should possess the following key capabilities:

• Link bonding that combines multiple links into a single, robust data stream.
• Real-time, intelligent link assessment that dynamically evaluates the quality and availability of all communication links (cellular, satellite, SDR) and automatically steer to the traffic to the healthiest path.
• Prioritization of critical data that ensures vital command and control data and essential sensor information are prioritized for transmission, even in congested or degraded network conditions.
• Enhanced security that implements robust encryption and authentication protocols to protect communication links.
• Load balancing across multiple networks to aggregate bandwidth from diverse sources for higher throughput.
