2 AREDN Amateur Radio Emergency Data Network

3 SAC-AREDN Sacramento Metro Area Amateur Radio Emergency Data Network A working group to establish an AREDN mesh network in our local area.

4 What is AREDN AREDN software is adhoc WiFi with OLSR routing for Mesh Networking. The WiFi router is based on the OpenWRT software. AREDN, OpenWRT, and OLSR are all open source. AREDN is designed to run on off the shelf WISP hardware.

5 What is OLSR The Optimized Link State Routing Protocol (OLSR) is an IP routing protocol optimized for mobile ad hoc networks, which can also be used on other wireless ad hoc networks. OLSR is a proactive link-state routing protocol, which uses hello and topology control (TC) messages to discover and then disseminate link state information throughout the mobile ad hoc network. Individual nodes use this topology information to compute next hop destinations for all nodes in the network using shortest hop forwarding paths.

6 AREDN History HSMM, or High Speed Multimedia, is the name of an ARRL sponsored technical Working Group dating back to January In January 2004 the OpenWRT project was started to develop enhanced Linux based router software for the Linksys routers. By January 2006, dissatisfied with ARRL s unwillingness to communicate the Working Group Recommendations to the FCC, all but one member resigned. In that short period HSMM spawned Broadband HamNet (BBHN) and several other similar efforts. The BBHN effort was based on the OpenWRT software. In February of 2014 the BBHN Development Team agreed to enhance and extend the Linksys WRT54G genre of HSMM to better serve EmComm purposes. Amateur Radio Emergency Data Network (AREDN) was born with the goal of utilizing Wireless Internet Service Provider (WISP) commercial radios. The Linksys devices were dropped due to their limitations. Google ARRL HSMM Working Group for more details, it is an interesting read.
