but then comes the weather factor.
- jacquesm 14y agoOver links up to a few kilometers this is usually not a problem if you can get a line-of-sight setup.
- zalew 14y agoA few years ago I've had one for my office, I don't remember the exact location but it was in the 2-5km range, terrible reliability during storms and snowfall.
- jacquesm 14y agoWhat kind of setup was this? I've had a 34 Mbit dish based connection going for a few years through all kinds of weather and never so much as hickup. The thing that I was mostly worried about was frying some hapless bird :)
- zalew 14y agoSadly I don't know the exact hardware spec we had back then and now I'm not even able to obtain it. We had no cap so in certain hours we got up to ridiculously amazing speeds :) but crappy weather was sometimes a problem, and well, it's something that happens around here :D Maybe it was an installation problem, I don't know.
- jacquesm 14y agoHehe, good thing it is no longer in use or nearby, I'd love to track that problem down. I'd start off with simulating bad weather by moving the antennae a bit (or a bit more) from their true alignment and by putting up alu foil sheets on kites in between the stations :)
- oasisbob 14y agoFor RF, line-of-sight often isn't enough, one needs to worry about the Fresnel zone as well: http://www.zytrax.com/tech/wireless/fresnel.htm http://www.zytrax.com/tech/wireless/fresnel.htm Links will work until something changes in the zone (trees grow, get wet, &c), then it might get unreliable.
- drone 14y agoWe use a 6Mb point-to-point link via dish to a tower 2 miles away, and have never had a problem with weather - and we get some pretty serious storms here on the gulf coast.
- sageikosa 14y agoAt that scale, yes P2P is simpler to "run" than a cable. Not sure I could put one at my desk :-)
