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

No its an outdoor market

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.

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

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.

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

seems a bit flawed as all hot people are not infectious .

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

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

Yeah I found someone local who installs the Ubuiquity and he is qiving me a quote today

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

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

[dicky96]

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

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

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

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

there are wifi routers that connect together easily .my one will do it . never tried that though i just use it for my internet connection .

[CapLeaker]

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

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.

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!

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

@Curious George et al
I think the answer to this is somewhat geographic. You have to realise I live on an island that depends on tourism for 80% of GDP. It is one of five main tourist islands in the Canary Islands

We never recovered from lock down, many businesses and hotels have not reopened since March and there is a huge amount of unemployment here now.

We opened up up for tourism at the end of June for mainly domestic tourists from the Spanish mainland, and ended up back in lock down at the start of August due to a massive surge in cases.

The markets we are trying to re-open have been closed since then

Now the government say that from 12th November, no one is allowed to arrive on the islands without taking a negative covid test 48 hrs before arrival, and that also applies to residents who leave for more than 7 days.

What they are trying to do is make this a fortress where no-one can come here without testing negative first, and when here you follow restrictions to stop locally spread infections

Probably this the only way our economy can survive, and if it works we become a play ground for those wanting to take a holiday in the safest environment possible

I have a small part in this now and to be honest i feel proud to have that opportunity

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

I wouldn't want to bet a business on it! Just like a potential vaccine -- it MAY turn out OK... or, it may prove to be a flop and leave you with an investment and no customers.

"Don't quit your day job."

Well seeing as this is all off-the-shelf kit and software, just configured to do a job that is 'en-vogue' right now, risk isn't really a problem as there is no R&D budget as such. The system on the video I posted is the 'prototype' if you like on an 8 week trial (tomorrows market is week 4) and that's already been payed for, so I most certainly ain't out of pocket.

The only risk really was buying the kit for the first system and getting the word out to the right sort of people. Nothing ventured nothing gained yeah?

If the trial is considered successful I can soon get enough more kit of more systems - to order

Consider this question and answer honestly:

If the politicians decide to implement this technology, would you prefer to the the one who sold it to them or the one that didn't?

Honestly, i would not want my name associated with it in the slightest.

Sure but a fever is the most common symptom and anyone detected with an abnormal core temperature is then checked by a medical professional to see why.

Even if it catches a handful of cases and stops a few transmissions surely that is better than none?

The problem I see with checking temperatures, PCR tests, vaccines (when they materialize), etc. is it leaves folks with a false sense of security: "I'm not running a fever so I must not be sick".

Each time I go to the library or a medical provider's office, they check my temperature (noncontact thermometer). It ALWAYS reads a degree or more lower than my actual temperature. Huh??

A more effective solution is widespread testing -- often. "You were negative the last time we tested you -- but, positive now. Someone (or something) you came in contact with is the likely source and everyone that you've come into contact with is potentially infected."

Also it ain't even expensive... 400 market stalls all paying an extra 25 euros on the months rent (for one month only) = 10K euros and they are able to trade again.

Until someone notices an infection spread at one of these events DESPITE the precautions. You then have to worry that vendors will wonder why they are paying for something that isn't working; or, customers deciding that the precautions still don't guarantee their safety.

Remember, folks already are living with uncertainty. You're selling them a different TYPE of uncertainty, not certainty itself.

If the politicians decide to implement this technology, would you prefer to the the one who sold it to them or the one that didn't?

...........

And folks who are infectious aren't necessarily hot!


Sure but a fever is the most common symptom and anyone detected with an abnormal core temperature is then checked by a medical professional to see why.

Especially the hotel solution which continually monitors people as they walk between the rooms and communal areas each day, unobtrusively of course. And then should someone become symptomatic of anything that causes a fever during thier stay, it is easy to isolate that person and find everyone else they have been in close contact with. Not to mention other things like with the facial recognition and recording you would know who was in the hotel residential or communal areas if there is an emergency such as a fire. By the time emergency services arrive you could tell them who is not in the resort, who made it to the fire meeting point and who is missing. Time saves lives.

The AI can also spot people reserving sunbeds with towels at 7am - if you so wish LOL

So really, if you can have this technology why not? The governent here decided it is necessary to reopen outdoor events that have been closed for months and given the choice of this or nothing what is the better? Also which hotel would you prefer to holiday in? The one with this technology or the one without, given the choice.

Also it ain't even expensive... 400 market stalls all paying an extra 25 euros on the months rent (for one month only) = 10K euros and they are able to trade again.

They take COVID very seriously here - this may be why we have only 20 active cases out of a population near to 1 million (more including the tourists and six month winter stays who are here)

you should do the rightious thing and turn down the job rather than assist in this slow communist takeover.

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

The 900MHz solution looks interesting. The lower the frequency the better this could work. I will contact these guys and see what they can suggest

There are other frequency bands that may also be available to you (sorry, I don't know what's "legal" where you reside).

You can also buy "extended power" WiFi access points. These aren't legal in the US but may be where you are. In free air. locating one centrally may easily allow you to bridge the distance between "devices" (again, I'm thinking along the lines of separate in and out "devices")
