Welcome to the
Broadband-Hamnet of Ottawa-Gatineau
Amateur Radio Mesh Network



The Ottawa - Gatineau area amateur radio community operates and maintains a Broadband Hamnet� and AREDN
Mesh Network. Broadband-Hamnet (formerly called HSMM-Mesh�)  and AREDN make a high speed, self discovering, self configuring, fault tolerant, wireless computer network that can run for days from a fully charged car battery, or indefinitely with the addition of a modest solar array or other supplemental power source. The focus is on emergency communications.

The Ottawa - Gatineau network is growing steadily, as more users join the group. Amateur radio operators are invited to add their mesh node to the network. This can be accomplished using one of the following re-flashed equipment:
Note that a tower-located equipment with a gain antenna provides a much larger coverage area. With the proper equipment, distances of 20 km or more are possible. Note that dense foliage blocks the signal. This is a line-of-sight service.

The BBHN-Ottawa-Gatineau community is also present on Yahoo! Groups. For the the latest Ottawa-Gatineau mesh news and activities, please visit the BBHN-Ottawa-Gatineau Yahoo! Group .

For more information on the required hardware and the BBHN network features, please visit the BBHN website or the AREDN website.
