- | DMR is particularly challenging for Hams as it is digital technology playing in an analog world. Hams are used to just dialing in a frequency, tone, and offset and being able to get on a repeater. This his not how DMR works. DMR was designed for the commercial and government world, and with the next generation of DMR hitting the market, the older generation equipment is flooding the secondary market and being snapped up by Hams. It used to be cost prohibitive to purchase DMR radios, but there are plenty of discount radios being brought to market now.

+ | === Wide Network === | ||
+ | This is the flavor of the DMR system. There are three different flavors, DMR-MARC, DMRplus (DMR+), DCI, and BrandMeister. The architecture of each is a little bit different. We track the Wide Network because it influences the architecture of a client-radio codeplug. | ||
+ | |||
+ | === Local Network === | ||
+ | A local network is a group of repeaters that have very similar talk groups. They tend to be linked to each other through the talk groups in various ways and connect to the same c-bridge. | ||
+ | |||
+ | === c-Bridge === | ||
+ | This is like a server. The Local Networks connect to the c-bridge which handles the routing of talk groups. The c-bridge can route talk groups to other repeaters within the same local network or send it out to other c-bridges or even cross over to other Wide Networks. | ||
