Short Answer
DMR Roaming allows radios to switch between multiple provided locations. IP Site Connect connects DMR repeaters via IP, enabling multiple locations to work together. This is useful for industrial areas, municipalities, logistics centers, campuses, tunnel portals, or distributed operational locations. Key factors include coverage, network quality, group structure, IP connectivity, latency, redundancy, and proper programming.
A single repeater is not always sufficient. Once multiple buildings, locations, or outdoor areas need to be covered, location networking becomes relevant.
How Location Networking Works
Multiple repeaters are interconnected via IP. Radios utilize defined channels and can switch to the appropriate location depending on programming.
What Needs to be Planned
- Which locations and buildings need to be covered?
- Which groups should communicate across locations?
- How stable is the IP connection between repeaters?
- What fallbacks are available in case of network or power failure?
- How is roaming programmed and tested in the codeplug?
Common Errors
Repeaters are interconnected without cleanly planning talk groups, roaming lists, and IP redundancy. The network may appear large, but it remains unreliable in operation.
FAQ
What is IP Site Connect?
A DMR function that connects multiple repeaters via IP.
What does DMR Roaming mean?
The radio can switch between defined repeater locations when properly programmed.
Does every DMR network need roaming?
No. It is only worthwhile in cases with multiple locations or larger areas.
Is IP Site Connect the same as DMR Tier III?
No. Tier III is trunking capable system radio; IP Site Connect connects conventional DMR repeaters.
