ARKnet - Cupertino Emergency WiFi Network
In the name of emergency preparedness, Cupertino maintains a number of shipping containers throughout the city filled with emergency response equipment and supplies. Traditionally, if a disaster happens to be large enough to knock out communications, when citizens respond to activate these ARKs, these teams include Cupertino ARES members who tender communications back to the city Emergency Operations Center (EOC). In addition to voice communications, we also provide 1200 baud packet for long textual messages via the Santa Clara County's amazing AX.25 BBS system (Callsigns W1XSC-W6XSC). 1200 baud is a very useful data rate when compared to zero in the case of an emergency, but we decided that the time is ripe to start running some serious experiments moving data on the 5.8GHz band instead of on 144MHz.
Since emergency communications is a major part of the charter for ARKnet, we're only considering uses for the network where the entire application can be entirely self-contained within the network. There's no interacting with the cloud when the Internet is down, so all our applications need to be running on a local server with emergency power. This network will be "Cloud-Free!™"
90 degree beam width and 28 degree beam width variants). Mikrotik is unusual in that their products combine both good long-haul WiFi and commercial grade routing features in a single package. We looked at using Ubiquiti for the long-haul links (which I've used before), but being able to have the links also speak OSPF to make the network self-healing is attractive.
This kind of bandwidth is certainly usable for any of the applications we've come up with so far, and the next big step for ARKnet is that we need to start developing viable applications to run on this network which will be useful in the case of a disaster.
