![]() I may rather go directly with a solution that I know will work. Based on those data only, I am rather doubtful about spending the time (and money) to do a test that will probably fail. I have links I know will work with Metrolinq devices but, if some of the values posted here with LHG60 are the best that can be done, there is nearly no hope to achieve the same results with the LHG60. I agree those devices are very cheap but I would rather avoid wasting time if I could know in advance that there is no hope to get a stable link in a given situation. Depending where you are located, it's not that easy to set-up a test link. ![]() Sorry but that's not a good enough excuse not to provide any information. ![]() Do a testlink and see how it behaves and how the signals fluctuate with rain/snow. With this kind of gear and this pricing it is best to do some labour and test it for yourself. In the second case, the link is probably going to drop.Ī link calculator is also usefull to know if a new link is working more or less as expected or if there is really a problem with the installation. In the first case, you know that it should continue working even with some rain. If you say that a 1.5Km link should work with a rssi of -50 under clear weather, that's not at all the same as if you say it should have a rssi of -65. There is just no way to know if it will be the same for LHG60 without testing because we don't have any information about the expected signal level at a given distance under clear weather. Those links stayed up but because there was a lot of margin. You rate them for 1.5Km but under which condition? Perfect clear weather with little humidity in the air? Will it works with a reduced speed when raining or will it stop working all together because there is simply no margin at this distance? With other devices, I saw drop of 15-20dB on links over 1Km during storm. It's not perfect but it will still give an indication if you can expect the link to stay-up nearly always or if it will drop as soon as there is some rain. So yes, a link calculator based on ITU rain zone calculator is really needed. Over a few hundred meters, 60Ghz links are heavily dependent of rain condition. ![]() 60GHz is completely different from 2GHz, so the traditional calculators will not be useful. If you have clear line of sight, link will work. The distance limit is specifically indicated. ![]()
