Here’s where we buy most of our hardware:

• Metrix: We use the Metrix Mark-I kit for our outdoor nodes. They also sell indvidual Atheros and Prism radio cards. Members of partner community networks are eligible for a discount.
• Hyperlink: All of antennas and cabling come from Hyperlink Technologies. They’re slightly more expensive, but have a huge stock and quick turnaround.
• Soekris: The indoor nodes and weatherproof outdoor nodes use the net4526 board from Soekris
• iDotPC: We bought the mini-ITX nodes for the outdoor network from iDot in 2003.
• Atheros: Most of our nodes now use the AR5213 chipset from Atheros.

• Microsoft Research: Microsoft Research has been building indoor testbeds and evaluating multi-hop routing metrics. Their Mesh Connectivity Layer software for Windows XP is available on their site.
• Emulab: An open research testbed at Utah with 27 802.11-based PCs and motes.
• Orbit Lab: Another indoor testbed at Rutgers with 64 802.11 nodes (expanding to 400)
• TAPs: The TAPs project at Rice is building new radio hardware and a similar multi-hop wireless testbed.
• WisperNet: Another multi-hop wireless testbed starting up at CMU

For more information about mesh networking research, see the Mesh Networking Summit 2004 site for videos and a rough list of academic research projects in progress.

• SeattleWireless maintains a long list of community networks. Here are a few that take a multi-hop approach:
• Wireless Leiden: A point-to-point wireless network covering the Dutch city of Leiden.
• CU Wireless: Champaign-Urbana wireless are developing a test-bed and software around a link-state based routing protocol which uses ETX.
• MobileMesh: The MITRE MobileMesh software is a hop-count/link-state based routing protocol for Linux and Windows.
• LocustWorld: An AODV implementation for Linux which uses a hop-count routing metric.

• Vienna FreeNet: 30 node network on Linksys WRT54g APs running OLSR with the ETX metric
