FREQUENTLY ASKED QUESTIONS

1. What is a wireless intercom gateway and what does it do?

A wireless intercom gateway is a communication convergence device that enables interconnection between traditional analog or digital two-way radios (e.g., UHF/VHF bands) and IP-based communication systems such as SIP telephony, dispatch platforms, or PA systems. Its core function is to bridge communication silos, allowing radio users to communicate with IP phones, mobile devices, dispatch consoles, and other SIP endpoints.

2. What are typical use cases?

The gateway is suitable for scenarios where traditional radio systems need to integrate with IP‑based communications, including: Property management / campuses: connecting security radios with office IP phones and control centers. Industrial manufacturing: linking workshop radios to dispatch consoles and office telephone systems. Transportation: enabling communication between field staff in tunnels, ports, or airports and central command. Emergency response: rapid deployment of interoperable communication between on-scene radios and command-center systems.
