Details about the outdoor network are scattered throughout the wiki. Link-level performance measurements are available on the Interesting Things page and the Design document explains how the network was setup. You might also want to read more about the radios, antennas and cabling that we use. We’ve given out nearly 80 Roofnet nodes so far, but the network only has 30 operating nodes as of April 2005.

We’re working on a new deployment at the TentCity housing development in Boston. Tent City consists of over 200 residences spread over a 12-story high rise and a handful of four-story buildings. The current wireless network only doesn’t cover all of the residences, so we’re setting up a multi-hop network to cover the rest. We did a temporary deployment on April2 and found we can cover the entire complex with around 40 window units. The permanent installation will use the cheaper $80 wgt634u nodes. The new nodes use 802.11b/g radios and will not require roof-mounted antennas.

We also use an IndoorNetwork for experiments. Each node is also connected to the Stata Center network infrastructure, which makes it easy administer and collect traces. We’ve observed many of the same phenomena of intermediate links, etc. indoors as well as outdoors.

The original GridTestbed consisted of 30 PC-based nodes spread over two stories of the old LCS building at NE43. It was disassembled in 2004 and replaced by the newer Stata Center IndoorTestbed.
