That limit is for data as well, though depending on the cable you can go more and still work fine. There are special extenders and/or switches that will operate at longer distances. There is also specialized cable designed for longer distances but much more expensive GameChanger Cable | Datacom Solutions not quite 1000f though
Fiber or point to point wireless are your best bet if its really 1000f
Pre-terminated fibre is pretty easy to buy these days, as are fibre to ethernet convertors for use with switches that don't have a gbic port.
Temperature is a factor as well.

And here is how to calculate ethernet length.
Temperature's Effect on Ethernet Cable Length
Is it true that temperature can affect how your Ethernet data cable operates? The quick answer is yes. If you have read my other blogs, you know the real answer is never simple. Extreme high and low temperatures affect more than just achievable speed. They can affect cable integrity as well.

Getting comfortable
Yes, temperature can play a factor from what I read, and also the length of the patch cords.Temperature is a factor as well.

You can use a total of 33' of 24awg patch cable.
So if you have 68* with 23AWG solid copper ethernet, your run cannot be longer than 328'-33' (295') for the solid copper run. Smaller copper ethernet (26awg) will derate the run and the maximum distance will be decreased. Shorter patch cables will also increase the distance the ethernet can be ran.

So if I can get a 250' run to a place where there is power, can daisy chain another Poe switch from there for another 250' run?
yes.
I still think fibre would be better though.

yes, you can go at least 330 from run to run..
They also sell inline extenders that generally require poe to operate but you dont need the device on the end of the line to be poe.

There's a lot more things that interfere with wifi that just both ends being able to see each other.
A point to point wireless bridge is not the same as wifi.
In terms of radio signal it's exactly the same and is susceptible to the same RF and electromagnetic interference as the wifi you use in your house.
If you really want to stick with copper, they make extended distance Cat 6 cables, I know Superior Essex does with Powerwise, which is 22AWG, but none that hit 300m. There's other brands too. Usually all only do 200m at abysmal speeds, 1M or 10M, which is enough for some cameras or access devices. POE goes the distance pretty easily actually, power is pretty basic.
You could have a POE powered repeater with that to reach good speeds. Run 500ft of powerwise, POE repeater, another 500ft. That should go the distance if you don't need power at the far end (though many repeaters will deliver power as well). But you'd also be placing a device that could fail, presumably in the middle of a conduit halfway to the far end. You'd be better honestly with pre-terminated, pre-certified Multimode fiber, assuming you don't have much fiber related equipment.

If the remote site has no power as you stated, you're pretty much limited to covering that 1,000 ft. run with cable, as a wireless bridge or a media converter (fiber to Ethernet) are going to need power at the remote end.
Running that much metallic cable outdoors can be very attractive to ESD from nearby lightning strikes, causing extensive damage. If you go that route be sure to install Ethernet/POE surge protection at both ends to help, but not guarantee, protection. Unless you VERY seldom have any lightning, I'd try to avoid.
What does that leave?
If you have LOS (Line Of Sight) you could set up a single, high power 2.4GHz Ubiquiti, TP-LINK, Mikrotik or Cambium (and others) radio running in AP mode with any proprietary (such as AirMax, PharOS, eg.) and WDS protocol disabled and channel width set to 20MHz so smartphones, tablets and laptops with conventional Wi-Fi can use it. A 5GHz radio could be set up similarly (with appropriate channel width).
5GHz is more demanding when it comes to LOS, 2.4GHz can penetrate some foliage.
In any event, a site survey to determine feasibility would be in order, IMO, before you commit to any wireless purchase and install.

This seems to be the ideal way to go for this instance. Get cat cable to an in-between location that has power and daisy chain switches together.. thanks everyone for the options. Im sure all suggestions would work.yes, you can go at least 330 from run to run..
They also sell inline extenders that generally require poe to operate but you dont need the device on the end of the line to be poe.
but if you have power at 250 feet a cheap switch will work...PRODUCTS | Veracity

Just remember that daisy chaining switches ads points of failure - either from the device itself (which is unlikely) or someone unplugging it - more likely.

Understood, thank you
