When communication failure is not an option, you need technology that delivers without compromise. In the most challenging operational environments, conventional systems reach their limits — and that’s where KNL steps in.

At KNL, we have created a completely new approach to HF radio technology, building our systems differently from the start. Our cognitive networked wideband HF radios are a major breakthrough rather than a small improvement. We’ve designed radio systems that give you full control over your communications.

• Built on Finnish innovation
• Trusted by Defence Forces
• Engineered by expertise, refined by users
• Breakthrough technologies that make a difference

Built on Finnish innovation

KNL was born from the expertise of military radio engineers who understood the critical limitations of conventional HF communication systems.

The company name KNL, originates from Kyynel (Finnish for “teardrop”) and pays homage to Finland’s groundbreaking radio technology from World War II, a testament to our deep-rooted commitment to communication innovation.

Our product development and manufacturing operations are based in Finland, allowing us to maintain strict control over quality and security standards.

KNL team represents a professional fusion of military experience and technical mastery. Every team member holds Finnish government security clearance, ensuring the most sensitive defence information is handled professionally and carefully.

As part of Telenor, a telecommunications leader with over 165 years of industry presence, we combine pioneering innovation with the stability and resources necessary for sustained defence partnerships.

Trusted by defence forces

If the most demanding military organisations trust KNL’s solutions, you can be sure of their exceptional quality and reliability.

Our dedication to high-performance is not merely a promise; it is confirmed by the most demanding users worldwide.

The Finnish Defence Forces have implemented our cognitive networked HF system for tactical long-distance communications. Their selection was driven by reliability in extreme operational environments, cutting-edge performance in demanding communication scenarios, and technological innovation demonstrated through regular software updates.

The Swedish Defence Material Administration (FMV) has acquired our Cognitive Networked High Frequency (CNHF) system at the end of year 2024.

Engineered by expertise, refined by users

We maintain the highest standards of quality in defence and security applications through three key certifications.

• ISO9001 – A comprehensive quality management system, which ensures product quality and continuous improvement.
• AQAP2110 – NATO-specific quality assurance standard for defence procurement confirms the ability to meet essential military specifications.
• ISO27001 – Certifies the information security management system, guaranteeing the highest data protection and cybersecurity levels.

Our radios are tested according to strict industry standards, including the MIL-STD-810H standard verified by an independent third party. Testing includes water, drop, and temperature tests, among others.

Every product is created through dialogue to ensure that customer needs and the drivers of technological advancement are taken into account. This method ensures our solutions align with our client’s essential operational requirements.

Our customers highlight several strengths in their feedback:

• Exceptional product quality with documented performance in extreme conditions)
• Partnership with long-term commitment
• Transparent communication and iterative product development

These core practices have established KNL as a dependable partner for mission-critical communications.

Breakthrough technologies that make a difference

Trusted connectivity when others fail

KNL radios maintain reliable communications in environments and situations where conventional systems fail.

• Fast connectivity – Links are established in less than 0.5 seconds without operator intervention while monitoring over 4000 calling channels simultaneously to identify optimal frequencies.

• Self-optimising intelligence – Dynamic spectrum access continuously identifies available bandwidth in real-time, supports data rates up to 300 kbps, and automatically reconfigures connections when conditions change.

• Independent satellite-free communications – Our radios provide beyond-line-of-sight (BLOS) communications even when SATCOM services are down. They function completely independently of satellite, GNSS, and GPS services, ensuring communication continuity in denied environments with transmission ranges up to thousands of kilometres.

• National sovereignty in security – Users maintain complete control over their encryption keys with national encryption key generation, management, and operation capabilities, eliminating dependence on external security providers.

• Extreme performance – Our radios maintain optimal performance in temperatures from -40°C to +55°C and overcome also Arctic radio wave challenges such as ionospheric disturbances and Aurora Borealis interference, ensuring reliability in the most challenging operational environments.

Built for maximum security

Security is integrated throughout KNL’s radio systems, protecting critical communications across all operational contexts.

• Extremely difficult to jam – Cognitive frequency agility automatically detects and avoids jamming attempts. Built-in ECCM enables operations in congested and jammed environments where conventional systems fail.
• Military-grade encryption – AES256 encryption provides the highest level of security for all communications. Robust mode ensures message delivery even in challenging conditions, maintaining connectivity when it matters most.
• Enhanced operational security – With EMCON mode for receive-only operation in signal-restricted environments, and real-time spectrum monitoring to adapt to changing electromagnetic conditions.

Simple to operate

KNL radios are designed for operational simplicity, allowing users to focus on mission objectives rather than communications management.

• Mission-ready after one day – Operators achieve proficiency after just one day of training with intuitive interfaces and software-defined controls designed for modern users.
• Intuitive user interface – Turn-on-and-go functionality eliminates complex setup procedures, automatic channel selection removes manual frequency management tasks, and real-time propagation measurement replaces frequency prediction requirements.
• Flexible Integration – Web-based interface functions on standard computing devices (PCs, tablets, mobile phones) and standard communication protocols (XMPP, SMTP/IMAP, UDP/IP). This enables seamless application integration and direct compatibility with command systems, improving situational awareness.

Future-proof investment

KNL radios are designed to grow with your needs. Our software-defined platform enables continuous development through regular updates. This ensures your communication system remains technologically current without hardware replacement.

The approach dramatically reduces lifecycle costs by minimising training and maintenance expenses while providing a solution that adapts to your organisation’s changing requirements.
