Modular design facilitates rapid reconfiguration to adapt to changing mission parameters without requiring extensive downtime.
The device’s firmware is updateable via a dedicated software suite. Updates can be downloaded from CTS’s secure portal or transferred via USB‑C, allowing field operators to deploy new features or security patches efficiently.
Development History
Origin
The initial concept for the CBO-855 originated in 2019 within CTS’s Applied Research Division. The division was tasked with developing a portable signal interference system to address the growing need for small‑unit electronic warfare capabilities. Early prototypes were based on existing commercial signal analyzers, but the requirement for low weight and rapid deployment led to a significant redesign of the hardware architecture.
The project was assigned the internal code name “Project Beacon” and was funded through a joint partnership between CTS and a national defense research agency. The partnership facilitated access to advanced antenna materials and testing facilities.
Prototype Phase
During the prototype phase, the engineering team iterated over several chassis designs, ultimately selecting a composite material that balanced rigidity with weight constraints. The prototype was first fielded in controlled environments in late 2020, where it underwent rigorous signal integrity testing across a broad frequency range. Feedback from test operators highlighted the need for improved ergonomics, leading to the addition of a detachable handle and an adjustable tripod mount.
Testing also revealed issues with heat dissipation under high‑power jamming conditions. Engineers responded by integrating a passive cooling system composed of finned aluminum heat sinks and a small, low‑power fan that operates only during extended use.
Production
Following successful prototype trials, CTS entered a limited production run in early 2022. The manufacturing process involved precision machining of the chassis, integration of the antenna array using a phased‑array design, and stringent quality control of the power management circuitry. Production was limited to 1,200 units for initial field deployment, with plans for scaling to meet broader demand.
Once deployed, field units were paired with a specialized training program. Operators received instruction in both theoretical aspects of signal jamming and practical handling of the device. This training emphasized situational awareness, legal constraints, and ethical considerations surrounding the use of electronic warfare tools.
Operational Deployment
Military Applications
The CBO-855 was first fielded with elite tactical units in 2023. Its primary function within these units was to provide on‑the‑fly jamming of enemy communications and radar systems. Operators reported that the system could effectively neutralize low‑band communications while preserving higher‑frequency tactical channels for friendly use. The device’s compactness allowed it to be carried alongside other standard-issue gear without compromising mobility.
In addition to jamming, the CBO-855 served as a reconnaissance tool. By mapping the frequency spectrum in real time, operators could identify enemy transmitters and assess potential interference threats. This capability proved invaluable during counter‑insurgency operations in urban environments where communication networks were dense and multifaceted.
Civilian Use
After the initial military deployment, the CBO-855 entered the civilian market under a revised licensing regime. The civilian version, the CBO-855C, is designed for use by law enforcement, emergency response teams, and civilian contractors. Key differences include a lower maximum jamming power and additional software safeguards that enforce compliance with local telecommunications regulations.
Civilian operators utilize the device for disaster relief communications, where it can temporarily establish interference‑free channels for rescue teams. The device also aids in crowd control scenarios by jamming malicious drone communication links or preventing interference with critical communication infrastructure during large public events.

Technical Analysis
Performance Metrics
Laboratory testing of the CBO-855 indicates a jamming effectiveness of up to 45 decibels across the 0.5–12 GHz range when operating at full power. The device’s signal capture capability allows it to achieve a signal‑to‑noise ratio (SNR) of 30 dB for weak transmitters at distances up to 500 meters. The system’s reactive jamming feature can lock onto active signals and deliver interference with a latency of less than 20 milliseconds.
Power consumption is a critical parameter for field deployment. Under normal operating conditions, the CBO-855 consumes approximately 25 watts, while full‑power jamming increases consumption to 80 watts. The integrated cooling system maintains operating temperatures below 45 degrees Celsius, even under continuous high‑power output.
Comparative Studies
When compared to earlier models in the CTS line, such as the CBO-752, the CBO-855 demonstrates a 60 percent improvement in weight reduction and a 35 percent increase in jamming power. Studies conducted by independent defense research institutions corroborate these findings, noting the CBO-855’s superior performance in field conditions characterized by high electromagnetic interference.
Comparative analyses also highlight the system’s advantage over commercially available signal jammers. While commercial devices typically operate within a narrow frequency band and provide limited analytical capabilities, the CBO-855’s wideband coverage and integrated spectrum analysis provide a comprehensive operational picture.
Limitations
Despite its advanced features, the CBO-855 has several operational limitations. First, its reliance on a single power source limits the duration of sustained jamming operations. While battery management mitigates this, large‑scale operations may require multiple units to maintain coverage. Second, the device’s jamming capability is primarily directed at conventional radio and radar systems; it is less effective against sophisticated encrypted or low‑probability-of-intercept (LPI) communications. Finally, legal constraints in many jurisdictions restrict the use of jamming devices, requiring operators to obtain permits or operate within specified parameters.
Variants and Upgrades
CBO-855A
The CBO-855A variant introduced in 2024 added a dual‑band antenna capable of simultaneous operation on the 0.5–6 GHz and 6–12 GHz ranges. The upgrade also included firmware enhancements that improved signal detection algorithms, allowing for faster frequency scanning. Additionally, the A variant incorporated an optional external storage module, facilitating the logging of intercepted signals for post‑mission analysis.
Operators reported that the A variant’s dual‑band capability improved situational awareness, particularly in urban environments where frequency congestion is high. The variant also reduced the time required to switch between frequency bands, a critical advantage during fast‑paced operations.
CBO-855B
The CBO-855B, released in 2025, focused on enhancing the device’s portability. This version reduced the chassis weight by 0.3 kilograms through the use of advanced composite materials and eliminated the need for the external tripod. The B variant also integrated a lightweight solar charging panel on the rear of the chassis, allowing for limited recharging in the field under direct sunlight.
Field trials indicated that the B variant’s lighter weight improved operator endurance during extended missions. However, the removal of the tripod mount required operators to rely on improvised mounting solutions, which may affect stability during high‑power jamming.
CBO-855C
Designed for civilian operators, the CBO-855C incorporates stricter power limits and software safeguards to ensure compliance with civilian telecommunications regulations. The device’s jamming capability is capped at 30 dB, and the system includes an auto‑shutdown feature that activates when frequencies associated with critical infrastructure are detected.
The civilian variant also offers enhanced encryption for data transfer between units, ensuring that intercepted signals are protected during analysis. Operators use the device primarily for disaster response and crowd control, where temporary, low‑power jamming can alleviate interference on emergency communication networks.
Controversies and Legal Issues
Export Controls
The CBO-855 is classified under the International Traffic in Arms Regulations (ITAR) as a dual‑use technology. Export licenses are required for all foreign sales, and CTS must comply with the Department of Commerce’s Export Administration Regulations (EAR). The complexity of these regulations has limited the device’s availability to a handful of allied nations.
Several high‑profile incidents involving unauthorized export of the CBO-855 have led to increased scrutiny by regulatory agencies. In 2026, an investigation revealed that a contractor had shipped a batch of CBO-855 units to a third‑country entity without proper licensing. The incident prompted CTS to revise its export procedures and implement additional training for its procurement staff.
Ethical Debates
Electronic warfare tools, including the CBO-855, have sparked ethical debates regarding the potential for unintended disruption of civilian communications. Critics argue that widespread use of signal jamming can interfere with emergency services, navigation systems, and public safety networks. Supporters counter that when used responsibly and within legal frameworks, these tools provide a necessary countermeasure against hostile communications.
Regulatory bodies have established guidelines that restrict the use of jamming devices to military operations within sovereign borders, and operators are required to conduct impact assessments before deployment. The CBO-855’s built‑in software safeguards are designed to assist in these assessments by providing real‑time spectrum data and auto‑shutdown features to protect critical frequencies.
Future Prospects
Looking forward, CTS is exploring integration of the CBO-855 platform with artificial intelligence (AI) systems to enable autonomous signal detection and jamming. Early prototypes demonstrate the feasibility of a “smart jammer” that can adapt to changing electromagnetic environments without direct operator input.
In collaboration with a leading research institute, CTS has also begun investigating the use of metamaterial antennas that could further reduce device weight while improving jamming efficiency. The company’s roadmap indicates that next‑generation devices may offer real‑time encryption of intercepted signals, enhancing the security of the data collected during operations.
Conclusion
The CBO-855 represents a significant leap forward in portable electronic warfare technology. Its wideband jamming capabilities, integrated spectrum analysis, and modular design make it a versatile tool for both military and civilian applications. However, its deployment must navigate complex legal frameworks and ethical considerations. Continued research and development aim to refine the device’s capabilities while ensuring responsible use in accordance with international norms.
