Each “master” radio has its own subnet and all “managed” nodes associating with the master live in that subnet. The standard subnet size is a /28 (netmask 255.255.255.240) allowing for up to 14 nodes in the subnet. By convention, the lowest-numbered IP address is used for the master node, or in the case of ethernet subnets for the default gateway. text/html 2006-04-30T02:03:00-07:00 Wiki Master http://www.diablo.sbarc.org/doku.php?id=top&amp;rev=1146387780&do=diff1146387780 The goal of the Diablo Link project is to bring back interesting video images from Santa Cruz islands to researchers, educational institutions, and even your living room. We hope to combine amateur radio, computers, mountain-top repeaters, video cameras, and operational know-how into an interesting project that offers many technical challenges, ample room for experimentation, as well as exciting applications that capture interest in the larger community. text/html 2005-12-18T10:26:09-07:00 Wiki Master http://www.diablo.sbarc.org/doku.php?id=wireless:ospf&amp;rev=1134930369&do=diff1134930369 /etc/zebra/ospfd.conf hostname diablo1-ospfd password zebra enable password zebra log file /var/log/zebra/ospfd.log Interface definitions configure routes going through each interfaces. The hello-inerval is how often to talk to peers (in seconds). 4*hello-interval is the dead-timer after which the link is declared down. The cost is the metric inserted for routes learned through the interface, it is additive hop-by-hop. text/html 2005-12-18T10:00:36-07:00 Wiki Master http://www.diablo.sbarc.org/doku.php?id=system_documentation&amp;rev=1134928836&do=diff1134928836 The Diablo Project currently runs 3 wireless point-to-point links: * A 32 mile link across the Santa Barbara channel from Diablo Peak at about 2500’ on Santa Cruz Island to a location (called WCC) at 2100’ near San Marcos pass just north of Goleta. * A 26 mile link across the channel from Diablo Peak to La Vigia at about 450’ on the “mesa” near downtown Santa Barbara. * A 9 mile link between La Vigia and WCC. text/html 2005-11-10T22:18:48-07:00 Wiki Master http://www.diablo.sbarc.org/doku.php?id=wireless:wifi_tidbits&amp;rev=1131689928&do=diff1131689928 802.11b/g Frequencies Non-overlap The spectral mask for 802.11b requires that the signal be attenuated by at least 30 dB from its peak energy at ±11 MHz from the center frequency, and attenuated by at least 50 dB from its peak energy at ±22 MHz from the center frequency. <http://en.wikipedia.org/wiki/802.11>
