Introduction to DMR

DMR Network Architecture

Linking Infrastructure

As previously mentioned, a Linking Infrastructure, or IP backbone, is used to interconnect the various elements of the DMR network. The DMR trunked network connects the radio sites together using an Internet Protocol.
There are many advantages of using an IP. For starters, it’s very flexible. Internet Protocols use a fault-tolerant, easy-to-handle connectionless architecture, they are scalable, so it’s easy to meet future requirements and of course, they are secure.

By using a Linking Infrastructure, you also reduce bandwidth consumption by using high-performance compression algorithms. Lower line costs ensure a fully redundant ring architecture that can be used versus a hub and spoke plan, and also there are lower maintenance costs as only one infrastructure for data and voice needs to be maintained.

Quality of service is higher, and network management is easily accessible via web-enabled applications and interfaces, so as you can see, the IP backbone simply makes things easier.
