Just what exactly *is* HSMM?
HSMM stands for High Speed MultiMedia…which still really doesn’t do much in the way of an explanation, does it?
Please consider this the “Cliff Notes” of HSMM… I’m quite sure that others will have variations as well as much more elegant descriptions.
The following definition is straight from the http://hsmm-mesh.org website:
| HSMM-MESH™ is 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.
In its current form it is built using the Linksys WRT54GL wireless router and operates on channels 1-6 of the 2.4GHz ISM band, which overlaps with the upper portion of the 13cm amateur radio band. Other platforms and bands may be supported as development resources permit. OLSR is used for auto linking of the mesh node radios. OpenWRT firmware tools are used for firmware development. |
A VERY good seminar was presented in Lucas, Texas by Kipton Morevec, AE5IB in 2010. This is one of the best articles I’ve seen that consolidates HSMM related information and presents it in an easy to understand format.
It’s a large download…about 30mb. Please be patient. You can view this article here.
The router to the left is probably very familiar to many. It is the Linksys WRT54GL broadband router which has been in wide use by many residential users for home-level Internet access. This router is readily available on eBay, Amazon and other sources. It is the “platform of choice” for the HSMM firmware. Other models of router are definitely supported, but the WRT54GL is one of the most universally supported units.
