In the above networking scheme, a network administrator could setup an efficient computerized network, with the D-Stars providing the necessary long-distance link back to the central network. Linux computers make excellent routers, using a few of them with matching WiFi access ports, a field portable network may be built. Of course, application design would be necessary to minimize WAN traffic.
The above options are simple examples of how these radios may be deployed. Of course, some extensive homework needs to be done before the emergency requiring their use. The D-Stars are tools to provide a solution... they will not self-configure themselves.
The D-Star radios are wonderful units, and I can forsee many types of use, for both voice and data deployment assignments.
The radios are mobile, and may be used for digital and analog conversations in either simplex or repeater modes. The radios feature detachable heads, so it is possible to mount the radio under the seat, and put the head on a dashboard, and use it like any other radio. The radio supports 105 channels, and a variety of PL tones and tone squelch options. When in Digital mode, you can specify digital codes to open the squelch. Just be aware on your antenna choices... at 1.2 GHz, RG-58 breaks attenuates 1.8 dB per 10 feet. RG-8X is not much better. You might want to track down some cable such as LMR-240 that should attenuate around 1.0 dB for every 10 feet. Don't forget... you will need an N connector on the coax for your D-Star unit.
This radio is really attractive for data modes, and with the power of computers, one can really build a powerful network of computers with them.
The D-Stars could be used between a central internet server, and a number of mobile D-Star units. An example situation would be a collection of storm spotters with laptop computers in their car. The central D-Star radio would be hooked into the internet (with a firewall to block all of the non-essential protocols, so that security and bandwith are maintained), and the mobile radios dispatched to various locations. The mobile units would be wired to a laptop computer, and from there, storm spotters could download specialized web pages or email notices of weather updates and latest concerns. If that laptop is also wired to an APRS station, that same laptop could have another window open with spotter locations.
The D-Stars could also be used to link computer network systems together. An example situation is a central internet (or an EOC) server, and several D-Stars used as linking nodes.
