Tait Hosts DMR Interoperability Testing

In late August 2018, Tait Communications hosted a number of DMR manufacturers and suppliers at the Tait Christchurch campus.

The purpose of the visit was to conduct interoperability (IOP) testing with Tait Tier 3 network infrastructure to the latest standard. Senior technical representatives from Simoco, Kirisun, Excera, and Motorola carried out the tests and all found that their technology was compatible with the Tait DMR T3 network.

Tait was the first to bring DMR T3 to the market so it was important not only to update our interoperability to the latest standard, but also provide the IOP opportunity for manufacturers whom are newer to the market with DMR T3.

Recently, Tait received official interoperability (IOP) confirmation through the DMR Association.

Interoperability is important because it allows a broader choice of equipment for customers, and keeps prices down. Across a communications network, the various technologies and devices can only talk to each other by using similar protocols and standard interfaces which have been defined and understood, implemented and tested by all parties. In the past, closed protocols meant that equipment manufacturers would work with only one or two other vendors. Open protocols give customers flexibility and avoids vendor lock-in. So while some manufacturers still promote closed protocols – and it may seem less expensive initially – it is rarely in the customer’s long-term best interests.
