It's a commonly-discussed topic and is in the FAQ, although the typical solution is a wireless router, connected to the modem via Ethernet and powered via PoE. The router would either be outdoor rated or in an enclosure.]]> http://www.dslreports.com/forum/remark,21078510 Mon, 08 Sep 2008 20:32:15 EDT Re: [cable] Outdoor Cable modem??? http://www.dslreports.com/forum/remark,21078465 SteveP75904 : K, let me get this straight. Cable modem to directional patch antenna's with tree's in the line of sight connecting 2 buildings with 1 internet connection? or relaying cable modem to a separate building through patch antennas?

First thing I would do, get the cable company to move your line closer to antenna A so that it may be reached with cat5, your modem needs to stay indoors so you can reboot it without getting a ladder out and pulling apart a rigged up box, distance is 328 feet for cat5 (100 meters) and its measured by voltage drop between 2 network interfaces (32vDC drops alot on 24ga twisted pair, If its a clean install you can push 400 feet with cat5) cat6 is no different on distance limits only twists per foot of cable which actually shortens distance per cable foot. if these are "dumb" patch antennas (the ones with coax input and nothing else) they will require a bridge of some sort to MUX the cat5 ethernet to RF. Same exact scenario at the other end with antenna B, with a bridge to MUX back into cat5 for your ethernet.

From what I read the antenna's are already there just not connected to any type of modem or briging equipment?

The only catch is the antenna appears to be fixed; to you would probably have to do some "modification" if you wanted to attach a better antenna to it.

Could you please direct me to a store that sells the 5100? I noticed that on the motorola website but did not see them for sale.

Thanks!
Have you called Motorola? I'm sure they can point you to who sells them.

If that goes nowhere then try some Motorola Canopy resellers... they might be able to order them.

The distance is approx 300ft.
Well that is way over the 100 ft so playing around with different coax is not an option.

I'm at a loss how an antenna tuned to 700 Mhz talks to a standard DOCSIS modem. I must be missing something.

But back to the reason for this fun dialog. Sounds like the best, cheapest, easiest solution is to get a NEMA enclosure (perhaps with built in heater) and be done with it.

I would use different cable but the people that do the installs are not very technically inclined. For example if I explain to them what I am doing with a wireless bridge they would go cross-eyed and tell me "welp buddy its our policy the antenna connects directly to the cable modem, and go away". I hate to say it but they are basically rednecks that do the installs. I have had the service before and know it is good.

I have approval from the GM to try to do the install on our secondary building, so thats all the tech needs to know. I will have everything ready when he arrives. He will just run a short cable to the modem, and mount the antenna on the roof. The distance is approx 300ft. Which I will either cover by Cat6 or the wireless bridge.]]> http://www.dslreports.com/forum/remark,20826663 Mon, 21 Jul 2008 17:19:16 EDT Re: [cable] Outdoor Cable modem??? http://www.dslreports.com/forum/remark,20826557 tschmidt :

All I can say is that we connect an antenna to a plain jane cable modem. The company says that they can't run their cable more than 100ft.
OK if I understand correctly:

1) Antenna emulates some flavor of DOCSIS headend. Antenna it typically mounted on roof. NOTE: since antenna talks to a DOCSIS modem it must include active electronics which need power.

2) DOCSIS modem connects to coax feed from external antenna.

3) Residential router uses Ethernet to connect to modem to share WISP connection.

This begs a few more questions.

1) How does the antenna get power?

2) Distance is a function of type of coax used. Do you know what type of coax connects antenna to modem? What is the distance you need between antenna and modem if modem were mounted inside? Just want to get an idea of distance and how much it exceeds 100. If you are only a little too far may be able to used lower loss RG11 in place of RG 6 to get a little more distance.

The ISP is speednetllc.com if anyone knows something about how this really works do tell. From what I gather its just DOCSIS running over the air @700Mhz, hooked up to a cable modem.

What's acting as the exciter / transmitter? Certainly not the modem itself.

You should be able to do any length of cable between the modem and the actual transmitter (thereby making the distance between antenna and transmitter moot). Or are these cable modems that have built-in transmitters on that 700MHz band?]]> http://www.dslreports.com/forum/remark,20824817 Mon, 21 Jul 2008 12:08:41 EDT Re: [cable] Outdoor Cable modem??? http://www.dslreports.com/forum/remark,20824812 dgilbert : so you use a WISP, not a cable co ISP. they should have outdoor rated radios for you. have you evne talked to them about it?

BTW, if 700 mhz cannot cut thru teh blockage you have some serious trees!

From there I am either going to use two Cisco 1310 outdoor bridges or a very long Cat6 cable. The only other option is to use a signal booster halfway and leave the modem indoors.

said by dgilbert See Profile :

what exactly are you using for the antenna? as far as i can tell the 5120 does NOT have built in wireless so you must be using some type of wireless acces point/extender.
That's what I was thinking and don't see the need for an outdoor modem or weather box. What you really need here is an long Cat5 cable between your modem and access point. The modem can stay inside and still connect to your outdoor equipment. ;)

Edit: I reread this part...

Correction, you will need Cat6 cable for that long of a run.]]> http://www.dslreports.com/forum/remark,20819258 Sun, 20 Jul 2008 02:59:06 EDT Re: [cable] Outdoor Cable modem??? http://www.dslreports.com/forum/remark,20818340 r81984 : Have you tried calling SMC sales to buy that outdoor cable modem?
(800) SMC-4YOU

Or

Just buy any cable modem and put it into a weatherproof enclosure.

That may or may not be as big a problem as you think. The device dissipates heat. Device temperature will be warmer then air temp. If all else fails get a little heating element and thermostat to add more heat.

On the flip side need to make sure it does not get too hot in summer. Keeping it out of direct sunlight helps a lot.

if that is not acceptable, they make hoffman enclosures with built in heaters. not cheap, but available.

BTW, are you SURE this is a cable modem hooked to an antenna? sounds more like a wireless radio link than a cable modem.

At Lowe's, Home Depot they sell plastic electrical junction boxes as big as 12x12 and are weather tight. Buy the biggest one and put you cable modem inside. Drill a hole in the side or bottom and install a elbow facing down to route the wires thru. Mount the box somewhere in the shade and off the ground. Since the elbow sticks down water cannot get in, and the lid had a rubber seal around the edge.

I don't know if the box will be to hot but you could always drill air holes in the bottom and cover with mesh to keep the bugs out. A PC fan could also be put in to move the air around.

Something like this.

Cable modem, over the air antenna and Fixed Point Wireless?
