Networking and cable for additional building

[reefside]

I want to run cable and internet to my office that is 300-350 ft from the house on the same property. Do I need to run a coax and a cat 6 cable? (Coax for the cable tv and Cat 6 for the internet coming from the router inside the house)

Coax for the services (cable and internet) to the house has a splitter outside that connects multiple tvs and the modem. It is easy to access but I would then need an additional modem and pay for the additional service at the office.

I am assuming that I will have to run an ethernet cable from the router to the outside and attach to the cable that would deliver to the outbuilding. Not sure how much service would drop for either the cable or internet.

Do you have any advice, ideas or solutions?

Thanks in advance.

"300-350 ft" is right on the edge of max ethernet distance of 100 meters.

You need to go and really measure the distance. If you can get in under 300ft you can use just the coax cable using technology called MoCA. If you go above 328ft ethernet will likely not work and you will have to go with fiber instead of cat6 cable. You would have to go with another technology such as wireless or maybe some models of powerline network adapters.

First of all, thank you for your response.

The buildings are 100 ft away, but the cabling entrance are on opposite sides of the buildings (away from each other). I have a coax connection on the outside of both buildings and the accessory building cable then runs underground and into a service tray to the second floor and into the attic before splitting into multiple drops for tvs and 1 for internet. The house has 4 drops from the outside to 3 tvs and 1 to the modem and I have a distribution amp to make the tvs work. My estimate was 3 times the distance between the buildings to be safe.

I have a wireless router to use as a bridge to connect to allow internet for the computer and accessories in the second building.

Looking at the MoCa, it allows for 1 item to be connected via ethernet cable (my router for instance). How would you separate the signal to also allow for cable to multiple tvs? Would I run 2 separate coax cables, 1 for tv and 1 for the MoCA, or use a splitter to combine the signals outside before the long run to the other building?

I've been looking for a company nearby to help me but they don't want to work with a homeowner only commercial contracts. We are industrious enough (I think) to run cables and hook up equipment on our own. Of course, the easier the better.

I currently have 60 mbps download and 5 mbps upload speed at the house and would suspect there would be a drop in service somewhat. I considered looking into wireless, but I hear the drop in service is substantial and then I'm trying to stay out of running new wiring in the house (from the router to a dish for the relay and the same for the second building). I do have 2 coax drops side by side where the modem is located which could be a input and output for the MoCA. Ethernet and fiber would be difficult to run in the house.

I know there is a good solution, only to find the right one so I only have to do this once. I appreciate any more help you can provide.

moca is designed to carry tv and data on the same cable. You would put splitter on the coax just like normal to get multiple tv. Now that I try to find the links that show the frequencies all the stuff runs at I can't find it. The moca runs well above even normal cable tv.

This big thing is has issues with are directtv (directtv has their own moca type box) and some of the whole house dvr systems.

There are a couple of different ways to cable moca. If you have extra cables you are best not putting the moca on the same path as the cable modem comes into the house. You are best off putting it on the other side of the splitter.

Tonight is just not my night I used to have good diagrams of the ways to cable moca. If I find them back in a reasonable amount of time I will edit this post. There is actually too much information on how to do this in google.

...1 other thought. moca you will likely only get 100m maybe a little more. With a ethernet your would get a full gig if that matters at all.
