The AXIWI AT-350 is our newest full duplex model and is working on the 863 Mhz. It has a reach up to 300 meters. It contains a display which shows the channel and it indicates the battery charge.

It can be used for similar applications as the AXIWI AT-320. But with these features it could be used for larger sites such as stadiums and retail stores. The AT-350 contains much more possibilities. Read all about it below. The AT-350 is also more durable and solid. It has the IP54 certification for dust- and water resistant (please take note this is not completely waterproof).
