1.2
GHz high-speed D-STAR for emergency communications in Minnesota
Radio Amateurs in Minnesota have been using high speed
D-STAR link on 1.2 GHz as part of the Amateur Radio Disaster
Data Network.
Just after 9/11/01, some of the 11,000 licensed volunteer Amateur Radio
operators in Minnesota decided they could build a radio based data network
covering the region.
This network would provide a reliable "last ditch" email and
data capability in the event of an emergency that disabled or overloaded
normal communications channels. The first phase of the network was built
using AX.25 packet radio technology, which has been running to commercial
reliability
standards since 2002.
In order to meet the needs of the served agencies for modern, easy to
use web interface backup volunteer emergency communications, the volunteers
have now deployed a new D-STAR 100 kilobit data network.
This technology moves Amateur Radio back to where we belong - advancing
the state of the radio art.
The ICOM D-STAR 1.2 GHz Data Repeaters are in secure locations. They
support User-to-User connections at 90 kbps and the group use Linux back-end
sytems with Citadel mail and conferencing applications and allow multiple
served
agency data uplinks for application access including the Internet.
