I can't see how attenuators would have worked. I can imagine passive reflectors or re-radiators might work. Chicken wire comes in various sizes, at least three sizes here, that are significantly different as far as wavelength is concerned. The sizes I recall are 1cm, 3cm, and 7cm diameter hexagonal openings. It probably matters which sort you observed. This is an evironmental consideration for deployment. For my testing, I hope to exclude it as a constant part of the test ... the square mesh wire in the foreground of the photographs has holes about 10cm square, and is only 1m high, below the height of the access point. Fresnel effects will occur. I suspect that there might be an inverse relationship between the populations that OLPC hope to help and the availability of chicken wire to the point that it is used in boundary and house construction. Metal fabrication is expensive compared to the labour cost of house repair. -- James Cameron mailto:[EMAIL PROTECTED] http://quozl.netrek.org/ _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
