HOW TO networking in a existing building?

hunghit · Post by **hunghit** » Tue Nov 29, 2005 4:36 am

There is a rental-apartment building with about 7 floors. Now I want to setup internet connection sharing for all rooms.
The problems are:
- I dont want to reconstruct building wall to make cable line in wall, because they dont have network cable yet.
- The wireless solution cannot apply, because of verythick wall (tested)

So, how can we can make connection from central switch (where connect to some sharing-internet lines) to each room ?

*I think of using telephone line (dialup/ADSL?): Can you tell me more info about "how to"? (I want a higher speed connection more than dialup 56Kps If it can be; and hardware solution is better than software solution)

*I think of using television cable, but I also dont know much about this?

Very thank for any information or ideas.

It is possible to run lines through walls without opening them all up. You can just make a hole in the wall for the box where you will be placing the jack, and then drop the cables down that into the lower apartments. It is pretty easy with a bit of practice and the right tools.

Another option would be to just run the wires along the baseboards, or outside of the walls in some other way. It might not be the best looking, but it gets the job done. It is done pretty frequently in offices and such when they are retrofitted for networks.

I don't know of any technology that allows you to share a phone line or cable line for a small network. You could have the ISP setup a different cable/DSL internet account for each unit, but that is probably not what you are looking for.

In thinking how to set this up...how many individual apartments? I'd be looking at the approach of a good managed switch, creating a VLAN for each room. Keep things nice 'n secure for the tenants. Also depending on the number of apartments, what's the internet pipe? Might look into a router supporting dual WAN ports for load balancing a pair of connections.

Firstly, thank you all for usefull advices

ErikD, I was think of this solution but there some difficuties because of many conner of wall make it hard to setup line from room to the gain tube (electric tube between floors; I dont know what to call it). However I will consider this solution with electric engineers.
Because this a hotel with some standards so it cannot make line outside the wall.

objohn, I'ver heard about it but no info so thank for your suggestion. But I dont know how far this Wall-Plugged Ethernet Bridge can connect. OK I will get more info with Netgear.

YeOldeStonecat,

This building has 8 floors with about 10 apartment(almost 2 room) each floor.
I will consider management and security topic when I am sure about connections.
For the internet load balancing, maybe I will use some bonded-ADSL connection device such as FireBricks.

And any ideas?
Now I get some info about set up a DSLAM in near PBX(telephone), the same ADSL that telecom company do, but it not enough detail for me.

Bad news, Wall-Plugged Ethernet Bridge support only 110v electric line. In my country, it is 220v.

So, sounds like wireless is out.
Due to construction of walls, you'd rather not deal with running CAT5? No luck through conduits in ceiling or anything?
Any un-used pairs of spare phone line running into each room? Just to get a 10 meg connection?

Yes, I just want >2Mbps only (just for internet, not networking between rooms)
There are 1 phone line use for this connection if needed, because they have other phone lines (2->4 lines/apartment).

For running CAT5 in wall, I will estimate the time and how much impact of this work to building & customers.

I get the detail solution for setting up a small ADSL center (as ISP ADSL service center) with DSLAM (every apartment will have a ADSL line to my center room in first floors over telephone line). But it costs some much ($24K). I still looking for best suitale solution.

Thank for all.

you can get wall plugged ethernet bridges for use in 220v power outlets- .eg the UK. I have a few of them. I posted the American link as i assumed you were a Yank!!

Look at the UK Netgear Site. There are also plenty of other manufacturers.
In terms on physical connectivity, these may be your best options then follow Cats suggestion of VLANS.

hope it helps

One more sad news,
For the wall plugged ethernet bridge, last year they already test it and did not get sactified because of some un-stable times (unknown reason), so the owner dont want this solution.

OK, I see that the ADSL center will be final solution. Test it ok with stable connection & speed. Finally the building owner still dont want to hardwire so that is the best solution.

Thank you for all.
