ACCESSNET®-T IP Uses HiveMQ for Reliable and Secure Messaging

The IP-based product ACCESSNET®-T IP includes hardware and software components to build up radio communication networks according to the European Telecommunications Standards Institute TETRA standard, which is used wherever reliability and security in radio communication are critical requirements, e.g. police, fire brigades, industry or public transport customers. ACCESSNET®-T IP consists of intelligent base stations handling all radio communication in a network cell and centrally hosted network management applications, such as radio subscriber management, infrastructure monitoring and system configuration management. In addition to all its functional capabilities, ACCESSNET®-T IP supports hardware and software redundancy, encrypted communication, secure authentication and audit trailing.

In close cooperation with HiveMQ’s engineers, the HiveMQ MQTT broker was introduced into the product to collect information on the technical status, capacity and radio user operations from all base stations in a communications system in near real time. This allows customers to monitor the availability and usage of the communication services and to enable additional capacity if needed – even automatically by an algorithm considering the radio frequencies already used in the range of the base station.

HiveMQ in Large Public Safety Networks

In contrast to the widely used SNMP based communication in telecommunication networks, the MQTT broker using extremely lightweight publish/subscribe messaging provides more flexibility, so that access to selected information in the network stored in MQTT topics can even be granted to customer applications using the HiveMQ authorization mechanisms. By using retained messages for important status information, new clients connecting the broker immediately get the latest status without information polling.

"In earlier versions of the product, we just collected status information and statistics counters using SNMP with rather long polling cycles. With MQTT, we now see status changes immediately and can even automate network management reactions."

Another key argument for using MQTT in ACCESSNET®-T IP was that it offers the flexibility of providing many specialized clients with exactly the data they need without affecting the bandwidth of the communication links to the base stations.

"After successful prototyping with open source MQTT implementations, such as Eclipse Mosquitto, we selected HiveMQ as the most reliable, secure and scaleable product on the market."
