Long Distance WIFI coverage

[chewychunga]

Im currently trying to set up a WIFI network for the marina in front of my house
problem im having is the distance i need to cover

Basic layout
Box at top is where router and ISP connection is
Was thinking about 5 unifi-ac-hd with 3 switches (one in office one half way each direction)
The only place to run the cable is in a channel with a 600v cable
Was wondering if fiber would be a better choice or stay with cat6? or what are the other options
We have about 50 boats at the marina at a time
any other suggestions would be very welcome
EDIT: pic not show up

First be sure you can do this with ethernet. It can only go 100 meters so you are going to have issues trying to place a switch/ap in your configuration.

If you are worried about interference it is mostly a non issue. If you were to run the wire say touching the electrical cable all the way you may generate interference. The main thing that prevents this is are the building/electrical codes most cites have. For safety reasons there are limitation on how close you can run what is considered low volatage cable to power. This include things like cable tv and telephone. If you follow the code requirements on spacing your ethernet cable will be relatively far away. I think the requirement is 18 inches in most cases. At these distance you should see no issues.

You may be better off with fiber just for your distance requirements. Problem is if you do this correctly and use fiber designed for burial you will have to pay someone to cut and terminate the fiber. The costs will likely be as much as the fiber itself. Terminating fiber is not a do it yourself things you need specialized equipment that is too expensive even if you would have the skills to use it.

On a side note be very sure you want to do this. You need to have systems to log usage and identify who is using things. Even in none open systems you will get people that will do illegal stuff and lawyers will come looking for you first. Maybe this is best a project to attempt to outsource to a ISP who has solved all these problems in the past.

where im currently building it theres no codes on the wire run due to it being inside a dock on the water and i was basically planning on running the cable laying on the other one (its the only place to run it)
is there other types of fiber i can use?
and the systems to log and ID people i have already set up (a few people already using just basic WIFI from router)
i was looking at a installer but the price was prohibitive (over $3000)
the 100m issue is why i was going to install switches half way down each run
And just noticed numbers should be FT not M.. Woops my bad on drawing

Be very careful building/electrical codes apply even on private property. This is part of the reason permits are require for work even inside your house.

Before you changed your distances you would even have to use single mode fiber because you exceeded multimode distances.

Maybe your best bet is to run your ethernet in flexible metallic liquid tight electrical conduit. This would be a much better protection if a short would develop in the power.

It is hard to say if this is going to work. Ethernet cable is extremely resistant to interference and power cable is also low frequency so that causes even less. This is not something that i suspect has been tested a lot because it generally in not legal to install ethernet in parallel to power cables.

You need switches that are rated for extended temperature range since these will be outdoors in weatherproof enclosures. Are these switches going to have local power or do they have to be POE powered ? How are you going to power the APs? The Unifi units you listed are not outdoor rated. Should you pick outdoor rated APs ?

i thought they were " indoor/outdoor, high-performance, 802.11AC Wave 2 dual-band access point"
i was planning on having power at the switches in middle of run but PoE at ends.. but can run power to ends if suggested
Im looking into the code but not finding anything cause its considered marine not residential or commercial
Im doing the installation myself (marine electrician)
i am willing to buy tools (ill use knowledge and tools to install stuff on yachts in future)
looking for suggestions cause im trying to learn cause ive never done data just other low and high voltage
Is fiber a viable option?
was thinking fiber cause i wouldn't need the switches at middle and could just use one at office in middle with no problem and i wouldn't have to upgrade wire in the future
Pros / cons / problems i might have with both?

They may be outdoor, but I don't see an IP55 or IP68 rating to say they weatherproof. BUT, even their "outdoor" units don't show an IP rating. It may just be me not seeing what I expected to see on the Ubiquiti webpage for an outdoor product.
