Public Safety, Security and Defense

KNL Networks communicationsolutions are for situations where failure is not acceptable. Whether it's a natural disaster, a peacekeeping mission, or a military operation, we have solutions for keeping you always online.

Independent network with the highest security

The CNHF radio system is a complete, infrastructure independent, MESH-radio network operating on the HF spectrum. For security and defence, CNHF offers long-range IP-based communications with the highest performance, security and reliability.

With our radio system, the user can establish their own independent communication network ranging from few kilometers to thousands of kilometers. This enables the required communications in military and humanitarian operations – just to name a few possible use cases.

Receive the whole HF frequency band simultaniously


Proprietary wide band ALE protocol


Built-in cognitive engine, which manages the spectrum automatically
Typical link establishment time less than 500ms
Data rates: 700-153000 bits/second, selected automatically in the RTS - CTS handshake

Easy-to-use FastALE Software

FastALE is a communication software for legacy radios

FastALE boosts the performance to a new level comparing to existing radios in 2G or 3G ALE modes. On top of that, it adds networking capabilities to legacy radios and enables interoperability with a CNHF radio system – all in a stand-alone PC software. FastALE runs under Linux OS. It includes networking protocols, a Cognitive Engine, a proprietary MAC-layer and efficient modems for data transmissions. The ease of use has been one of the main design principles of FastALE. It allows users to concentrate on operations instead of configuring the communication systems and operating the radios.

The main technical features include

RTS - CTS handshake

53ms each

Data rates 900-14400 bit/s

Selected automatically in the handshake

Automatic frequency list generation
Link establishment time less than 500ms*

(3rd party radio hardware limited)

Includes a network configuration tool


Compatable with all legacy radios with PC control functionality and audio in/out


Surveillance sensor system


We allow our users to monitor different targets safely and reliably from long distance with our surveillance sensor system. The system includes integrated state-of-the-art sensor network(s) and long-range sensor network radios.

The sensors include IR and daylight cameras, motion detectors, magnetic sensors, movement detectors and acoustic sensors. They can be linked to each other via wired connections or short range radios. The data automatically transmitted to the command post. Sensor fields and all the individual sensors can be monitored and controlled over the air from a remote location.

Surveillance sensor network is developed in co-operation with KNL and Haltian.

The main technical features include

Operating time with batteries

14 days

Max. number of sensor fields controlled by one command post


Distance from command post to sensor field

Up to 600km

Max. number of sensors in one sensor field


Time from detection to alert

Typically less than 10 seconds
