Axiwi AT-350 – 1 additional referee intercom for the REF-X set

AXIWI two-way communication systems are on FIFA’s (Fédération Internationale de Football Association) list of referee communication systems. AXIWI are professional systems for sports referees and are used by football and referee organizations worldwide (see references here).

What is the AXIWI intercom system?
AXIWI is a professional, miniature, two-way full-duplex hands-free communication system. Six people can communicate with each other simultaneously in conference mode, just like during a phone call.
The AT-350 is the latest full-duplex model for sports referees from Dutch company Axitour.
It can be used for similar applications as the AXIWI AT-320, but offers significantly more capabilities.
The AT-350 has longer battery life and is more durable – it has IP54 certification for dust and water resistance.
This makes the system more suitable for outdoor use in environments exposed to moisture, water splashes, dust and dirt.
It offers up to 300 meters transmission range in line of sight.
The AXIWI AT-350 operates on the license-free 863 MHz – 865 MHz radio frequency band approved by the European Telecommunications Standards Institute.
It has 8 radio channels for communication, and up to 250 people can use each channel. Additionally, the intercom is equipped with a clip, armband and lanyard holder.

The AXIWI communication system was designed for sports referees, coaches and trainers in most sports disciplines, such as:
– handball,
– korfball,
– basketball,
– football,
– field hockey,
– volleyball,
– baseball,
– water polo,
