Getting Cell Signal and Wifi To Detached Shop

I just built a shop behind my house and I noticed when I am inside with all the doors closed, I get zero cell service or Wifi. The shop is about 70' from the house, and 100' from my wireless router. I have a Google Nest wifi system with one router and one point in the house. Do you think by just adding another google point inside of the shop that it could fix the problem? Outside of that what are other options?

Also, any recommendations for a simple cell booster that may bring the signal from outside the building to inside? Thanks

Bury an ethernet cable from house to the shop. Or fiber.

These guys are the solution to your problem.

If your phone doesn't pick up the wifi inside the shop, neither will the mesh point. You could try getting another point and put it inside the house (or maybe under covered outdoor space) near the shop where the signal is decent. Your other options:

1. Powerline adapters
Easy and cheap
May work great
May work shitty
May not work at all

2. Run ethernet cable
Best option
Should have done while building
May be a pain or impossible at this point, or may cost a lot

3. Wireless bridge (many options available)
Cheaper and easier than running cable in many cases
Very solid, very fast (though not as fast as hard wire)
Usually relatively small and not offensive looking, but it will still be shite hanging on your house/shop

Shielded ethernet in a buried conduit, or fiber in a buried conduit.

Shielded ethernet
Can you explain in technical terms the reason for using shielded cable between buildings? Is it to prevent creating a voltage potential? Ground loop issues? Are those the same thing? Wouldn't the same problem exist if you run cable between two devices which are inside the same building and plugged into two different circuits?

I personally prefer shielded because the extra layering helps against the elements. You use it indoors if you think you're going to be running into a lot of interference, but outdoors you're less likely unless you're using the same conduit to run electrical (which some places tend to do). Conduit + shielded in this situation is probably just my personal preference and a good bit of overkill, but if you want to use the conduit for other wiring then definitely get the shielded.

Not for voltage issues really - your ethernet barely carries an electrical charge in comparison to actual electrical cables (but obviously can carry a surge). I know some folks will just lay a shielded cable on the ground and think that's enough, but rarely think about animals, or forgetting its there and hitting it with a mower, etc.

So yeah, don't think of ethernet cabling like electrical wiring. Shielding ethernet isn't for the same purposes.

Pretty sure that's a code no-no.

Newer PoE can approach 100 watts! Not on par with electrical but can still cause lots of damage.



Admittedly I'm not at an engineer's or electrician's level of understanding electricity, but as I understood it if there is too much difference between ground voltage at either end of a cable, it can create unwanted current to flow, and the drain wire in shielded cable prevents this. I know that ground loops are an issue inside the same house on different circuits with audio equipment, so I guess I don't get why it would or wouldn't be a problem for network equipment.

Your electrical knowledge is well above mine, so I cannot speak on some of what you're asking. EE was my father's field, I'm purely IT.

That said, I have seen grounded ethernet cables when they've run outdoors but that's rare. I know you can go unshielded in a direct burial, but I've been running fiber for years now for my outdoor cabling to avoid worrying about the scenarios for each type.

This blog is from someone smarter than me at this. It probably answers your questions.

How to fix a ground loop

I used to know a lot more but honestly haven't used ethernet outdoors in a long time.

So if I understand that correctly, then ground loops are only an issue when you use shielded cable. Unshielded cable does not have that problem because none of the conductors are grounds nor referenced to ground. I guess?

The only thing I'm sure of is it's all very complicated.

Yeah, you should be okay if you use unshielded in a controlled environment, but use shielded if you are going to expose it to air.

Or just go fiber and an sfp. That's what I would do.

No need for shielded. Just run indoor/outdoor CAT6 and bury it in conduit. Preferably 18” depth minimum. If it’s buried in conduit it’s not exposed to the elements and a shielded cable doesn’t help in that instance. What would be appropriate would be direct burial CAT6 in that application.

Are you able to move the router so that it is on the side of the house where your shop is? You could take your satellite and plug it in in the shop and see if the signal reaches. If not, you could try one of the newer mesh systems that have better range and see if it works. Take it back if it doesn't. If it works, it would be a lot less expensive than running cable.

I know Tom's tests on newer systems show that the signal degrades about 40-60% with some systems, but 93% on the Google Wifi at 150 ft. One of those newer systems from Linksys or Netgear might have enough coverage to take are of you.



I recently purchased an Orbi mesh wifi and my modem and wifi router are in my detached garage. My satellite is about 45' away from my router in a 100 year old brick house. My signal is fantastic in the house. My wireless signal gives me about 400 mbps down in the garage and 300 mbps in the house. I still get about 80 mbps from the router (with the satellite turned off) on the opposite side of the house from where the router is in the garage , and that is probably about 70' from the router and with a lot of walls in between the two.
