Steel building - wifi question

April 2, 2013 at 21:51:12
Specs: Win vista
I am moving into a steel building within the next couple of months. it has tin siding FYI. I had a question about the Internet.

I live rural and the internet will be received through an atenna on the roof. The antenna will be pointed to an access point (which in my case is a tower that is within my line of sight.) I will get it within the building through a cable that will either be connected to my computer or router.

My question is will I have any trouble receiving the Internet signal to the antenna due to the building type/siding? Also, if I wanted to hook the cable to my router for wifi will I have any trouble broadcasting and receiving it within the building?

Just from going on my limited knowledge about this stuff I don't think I will have any issues but I wanted to ask those who are more experienced than I just to be sure.

If you can get the antenna outside the building, up on the roof, than you won't have any interferance from the building, and line of sight is the ideal situation. However, you will pay dearly for every foot of coaxial cable, particularly if you use garbage cable. I only use coax if I have to, and when I do, I only use low loss LMR400. There are workarounds for your situation, though. You should consider an equiptment upgrade, what I would recomend would be a high power outdoor POE router, with DD-WRT preferably, so you have the option to use it as a bridge or a repeater. Ubiquiti Networks specializes in this sort of stuff, and at the most affordable prices. This is WISP as opposed to SOHO, but at a SOHO price. As a bridge, the router serves as a client, becoming a wireless "patch" for your wired lan, either your computer's earthnet port, or another router's wan port. With my Ubiquity Bullet2HP for example, the idea is to attach the router directly to the antenna, outside, so there is NO coaxial cable at all, so no loss. Data streams through the earthnet cable, as does the d/c power supply. so that it needs only the earthnet wire to connect it. The Bullet2HP stands for "high power", @ 800mw, with an Atheros WIOSK chipset, it gets amazing performance, anyway. You connect that either to your pc, or another router (inside the building), this is then a repeater. But DD-WRT has a repeater mode, where it will connect wirelessly to another wireless AP as it's WAN, while also broadcasting an SSID and serving as a wireless AP at the same time. The advantage to using a seperate router as the AP is that you can set that up inside the building, but you would only need to consider that if you have trouble connecting to the router on the roof. Check out Streakwave wireless for the best deals on Ubiquiti equiptment. Also, my all time best wireless card ever (am into the wireless, I build antennas, and collect long distance "QSL's" to public hotspots, I used to be into HAM radio, so I have used all sorts of wireless cards) is also from Ubiquiti, the Wifistation EXT (external antenna) client card. It has the FCC's legal limit of 1000mw, has a 10' usb cable, and is weatherproofed, so it can be outside connected directly to the antenna, with no coax. It gets about 50 AP's right now, from inside my house, which is a one story, and that is with the stock antenna that it came with. These are $30 at Streakwave, and I can assure you, there is nothing better, no matter what you spend on it. You can get away with the 10' usb cable and one 10' active repeater usb extention cable, in fact, I have used mine with 2 of them, for 30' of usb cable. If you can get that close to the antenna, that will do for you. But the POE can go through100' of earthnet cable, no problems.

Since you have an antenna on the outside of your building that will be receiving the signal, the short answer is, "You will not have any problem receiving the signal"

I would highly recommend you use a SOHO router inside your home to connect the antenna to. I would NOT recommend using DD-WRT on any router. In fact, I highly recommend against it. If you should find, like me, that you don't like it, you will then find it's nearly impossible to remove it from your router. I will not be held hostage by any person/company/business. (I tossed that router in the garbage and bought a replacement.) I would suggest that if you're not a computing professional like me, you don't need to fiddle with 3'd party firmware on routers. Just buy one that has all the features you want. (ie: dual radio, wireless, 4 LAN ports, etc)

Just FYI, not only am I a computing professional with over 15 years working in industry who works in enterprise networking, but I also live in a rural area and we have two wireless ISP's in our area so many people I know and work with are using the same setup as you. Around here, nobody uses coax from the antenna to the router....they use Cat5e or Cat6.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

I would love to know how you connect an antenna to a router with networking cable. This is impossible, the only way to make that kind of connection with networking cable is to use an other than soho router, which was my point.
And what was not to like about DD-WRT? Removing DD-WRT is the same in installing it, you download the original firmware (or the most up to date version of it) from the maker's website, and use the firmware flashing page in DD-WRT the same as with the original firmware.
