    Re: Need LAN connection over several hundred meters - how to do this?

    just adding in my 2 cents. the schematic of your idea in the first post is almost exactly like how we implement the trace together system for malls, buildings, places etc. in singapore so the infected and their contacts can be quickly found and isolated to reduce spread. so the idea is definitely sound and it works in reducing the spread of covid-19.

    the proof is in singapore's flat and non-existant curve. we are an island of 5.5 million people and we currently have 5 straight days of zero community cases and then followed by one day of 1-2 cases, then the pattern repeats over and over again. so well done in doing your part to help flatten the curve in your home!

    and yes singapore too is a covid fortress where no one can come in without first testing negative. thats why singapore is cracking down hard on illegal immigration lest illegals bring covid in here. vietnam was doing so well in containing covid-19 but an infected illegal immigrant from china ended up causing the danang outbreak and ended vietnam's clean sheet of zero covid deaths. ah well... when u snooze against covid, u lose... lol!

    i should get out more and stop working from home like chicken little... i may go out and see if i can figure out a proper detailed schematic of how singapore does the trace together system in buildings to compare and see if improvements in implementation can be done but no promises! if u dont hear back from me, it means im not quite done figuring it out yet. im not going to post in this thread anymore until i have something better to post. lol!

      All my network / internet stuff that is spanning anywhere from 300m to a few kilometers is done with wifi bridges. Look at Ubiquiti etc. I have some links going now for more than 10 years. All it ever happened was that the POE power supplies went bad. Or fiberoptic.

          using wifi outdoors in some european country's is very illegal - check your laws.

            We have that Ubiquity system here - it is how a lot of folks get their internet - from base stations around the hills/mountains

            Strangely enough, the local guy I needed to hep me with this is currently ill with flu - not covid - which is why I posted here as the quotation for solution is now urgent and this is not my area of expertise

            Thanks to all for advice - I do understand this topic is contraversial for some but in the case of our island communities it is essential we find a way to reopen our economies

              If I would be in your shoes, I'd just slap a ubiquity system there and be done with it.

                  Then I would say everyone need to stay home and just be safe

                  But I would hope that everyone is wearing the right type of face mask and and more than 6 feet apart from each other and limiting there exposure in other words only goes some where if you have to

                    It's very simple. The maximum length of cable in one network segment is 100m.
                    Use POE and put 3 switches, if it is inside a building.
                    Powerline is also an option, although you have to test it. These adapters are not very reliable.

                      No its an outdoor market

                      So I got a ubiquity omni directional antenna, and a directional dish shaped one - point the dish at the omni and it works

                        Then you have no other option, rather than either WLAN or eventually Powerline. Omni or panel antenna BS AP + panel or directional client AP-s.
