The PNG WICS system consists of a base station and a mission defined number of transceivers.

There is no physical/technical limit for the number of simultaneously connected transceivers in the communication network. However, the system can be configured to limit the number connected as well as control accessibility and features on a transceiver to transceiver basis (i.e. by serial number). The system can be controlled through its own proprietary CP50 control panel, or by a platform installed communication suite with an integrated PNG WICS system. The relevant interface control protocol will be disclosed to the vendor of the installed intercom for adaptation.

The base station supports multiple interfaces for audio through analog interfaces and select digital audio interfaces. The base station can deliver Push to Talk (PTT) signals to other systems, and trigger transmission based on a received PTT signal from other systems.

PNG WICS is headset or flight helmet agnostic. The PNG WICS transceiver automatically detects the connected microphone and performs auto-tuning to the connected headset. This allows users to utilize existing available headsets and helmet equipment.

The Axnes PNG WICS offers a unique and state-of-the-art software-defined radio.

The system operates a wireless link between the base station and the handheld transceivers in the UHF band. Exact frequency configuration is managed by the configuration software application. Frequency ranges can be customized, within the military and civilian UHF bands from 270 to 470MHz. Further customizations are available subject to limitations. The wireless link is a single frequency, full-duplex digital radio link.

Although currently available, the Axnes PNG WICS is continuously being developed with features and functionality advancements.

The Polycon wireless system has been developed in collaboration with UK RAF, Bristow and CHC Norway. The system provides rotary and fixed-wing operators with reliable communications and increased operational awareness by providing highly robust wireless communication between internal and external crew. Because of a very ruggedized design it is capable of doing this reliably in extremely harsh operating environments.

The Polycon system eliminates communication restrictions with outside crew. It provides seamless hands-free, continuous communications by extending the ICS to outside crew. Communication is continuous two way communication, supported by None Interrupted VOX and effective noise cancelling. Range is sufficient to allow the aircraft to move away, burn off fuel, or act as a relay station to avoid terrain if the outside crew needs to communicate back to base. The outside crew will stay on the ICS at all times, and is able to both continuously listen in to the communication between the rest of the crew, and to address them as within the aircraft. Down the wire he will also act as a second set of eyes for the crew inside. He is able to warn of terrain, power lines, or other obstacles that may be out of sight or difficult to designate for the pilot or the hoist operator. Increased safety is achieved by drastically improving situational awareness, and by reliability of communications. Also the operational window of the aircraft may in many cases be safely extended allowing better use of a valuable resource.

Axnes’ unique patented None Interrupted VOX together with noise cancelling on the microphone enables hands free communication when a remote crew member is on the hoist without saturating the ICS with outside noise. Customizable frequency and channel allocation provides support for multiple aircraft or multiple external crew members on a site.

A UHF based radio enables robust communication with a range of several km. More importantly a robust radio enables reliable communication even when a swimmer is in the water, or when a rescuer needs to enter windowed buildings or superstructures, if a rescue team is out of sight in woodlands, or if a medic is tending to casualties at a traffic accident where the helicopter is not able to set down close by. It is in these situations Polycon has proven to be unique within the industry, and when additional lives are saved.
