This protocol is optimized for “point to multipoint” topology, with the help of managed-TDMA. Bitrate is up to 500kbps (net, effective bitrate). </p> <p> The radio modem is cheap (~$80) and home-made, with a 433MHz <abbr title="Industrial, Scientific and Medical">ISM</abbr> module inside. The modem is connected locally with Ethernet, therefore no specific software is needed on PC. </p> </blockquote> <p> <a href="https://hackaday.io/project/164092-npr-new-packet-radio" class="urlextern" title="https://hackaday.io/project/164092-npr-new-packet-radio" rel="ugc nofollow">Link</a> </p> <p> <span style="color:#ff0000;">Update</span>: here&#039;s another <a href="https://spectrum.ieee.org/geek-life/hands-on/build-a-longdistance-data-network-using-ham-radio" class="urlextern" title="https://spectrum.ieee.org/geek-life/hands-on/build-a-longdistance-data-network-using-ham-radio" rel="ugc nofollow">article</a> that explains a bit of the history of the project. </p> </div>
