GENRIP for Ultra Low Cost Wireless Deployments
Gregory Perry writes "A South Florida company just released GENRIP, an open source (as in GPL) project for Linux that turns low cost serial line devices (such as 900 Mhz radios) into IP addressable nodes; right now the technology is being used by various robotics groups to replace existing wired tethers on robots with wireless radio links, but the important thing to mention is the ability to use cheap radios to create wireless lan segments without the power and cost requirements associated with 802.11 WLANS."
Fine, the equipment may be cheap -- and it sounds like you get what you pay for. But what about the cost of man hours it takes to get this up and running. Not to mention the man hours it will take to support some hodge-podge solution to wireless. For all the trouble you will have to go to to get this crappy solution going, you could afford 802.11b that works out of the box on most distros anymore.
If you want to save some money cutting corners, then build some cheap pringles cantennas or something.
