Commercial radio using IP network (Transceiver · Income)

This is a commercial radio device (transceiver/intercom) for corporate users that uses an IP network. Using a smartphone, you can operate it in the same way as a dedicated device.

■Main features

・Connect anywhere

Conventional wireless devices have limitations on connection distance, but they can be used anywhere with an internet connection such as 3G/4G/5G/Wi-Fi.

・Join 6 groups with one smartphone

There is no need to carry multiple smartphones when using communication networks for the whole group and small groups, or when a leader is responsible for multiple sites. You can also choose where to send the conversation.

・Unlimited number of devices to connect

Since there are no frequency restrictions, there is no limit to the number of smartphones that can be connected.

・High sound quality & low delay

Sony's proprietary audio algorithms, such as the "Intelligent Noise Filter" that separates ambient noise such as wind noise and the sound of cars running, leaving only the human voice, provide clear feedback control, noise cancellation, low latency measures, and audio MIX. It achieves improved sound quality and reduced communication traffic.

・Linkage with existing intercom system

By linking via an interface unit (separate arrangement required), it is possible to effectively utilize existing systems.

・PTT operation function using voice recognition

Sony's unique voice recognition technology allows PTT operation by voice. You can enter a call state by saying "PTT-on", "mic on", and "conversation on" into the microphone of your smartphone or earphone.

・Individual call function

You can make one-on-one calls with specified devices.

・Group call function

This function allows you to send a request to a group to respond to an individual call. The response request will be notified to all devices participating in the group, and an individual call will be started with the first device in the group that responds.
