[WISPA] Easy Ethernet up the tower
Hi guys, I am thinking of installing Ethernet junction boxes on my towers (top and bottom). The idea is to install a larger number of runs up the tower and run shorter runs from the box to the radios. The same at the bottom from the patch panel to the equipment/arrestors etc. Is anyone doing this? What kink of (water proof) boxes do you use and do you use a multiple CAT5 cables or do you run 48 or 96 pair? WISPA Wants You!

Re: [WISPA] Easy Ethernet up the tower
As Dylan mentioned, increased lightning damage could also be an issue with a single core cable. I run all my cables in a single bunch down the tower. They are individually shielded. And all the shielding is connected to the same ground of course. Regardless, they would also get power from the same source. I could put individual arrestors at the top of the tower. At the bottom I would have one for the AC and one for each Ethernet quad. On Tue, Mar 10, 2009 at 2:07 PM, Adam Goodman a...@wispring.com wrote: OK.

Re: [WISPA] Easy Ethernet up the tower
Why you want to make sure you properly ground and use surge arrestors. But not that much different to run separate cat5 runs. They are all connected to same AC source and plugged into the same switch etc so no different really. /Eje Sent via BlackBerry from T-Mobile -Original Message- From: Adam Goodman a...@wispring.com Date: Tue, 10 Mar 2009 14:14:55 To: WISPA General Listwireless@wispa.org Subject: Re: [WISPA] Easy Ethernet up the tower As Dylan mentioned, increased lightning damage could also be an issue with a single core cable.

Re: [WISPA] Easy Ethernet up the tower
I think you're making this more difficult than necessary. 25pr = 50 wires = 25 pair There are 8 wires in a standard CAT5 cable. 50 / 8 = 6.25 or more simply 48 / 8 = 6 Or as David illustrated there are four pairs in a standard CAT5 cable. So, if you take 24 pairs from the 25 pair cable and divide by 4 you get 6 giving you 6 cables. Regarding lightning; we haven't seen any increase in lightning risk with this type of installation and have several installed this way on a variety of structures and elevations. If your site is grounded properly I don't believe one cable is more susceptible to lightning strikes than six.

Re: [WISPA] Easy Ethernet up the tower
Uh, ok you can do this if you want to run more than six radios off of one 25pr cable...than sure. But why if you have the equivalent of six cables run? We just run another 25pr and double our radio capacity from 6 to 12.

Re: [WISPA] Easy Ethernet up the tower
There are 25 pairs of wires in a 25 pair cable. You only need 2 pair per run for standard ethernet (1,2,3 5 in a standard RJ45) So that gives you 12 connections between top and bottom. For power, use a separate power run to the cabinet (speaker wire!... just kidding!)

Re: [WISPA] Easy Ethernet up the tower
I guess the short answer, IMO and experience, is no. It's not as if we've just started doing this, but actually have years of experience with this type of very simple installation. Do you now understand that all six radios are NOT powered off of a single pair? Each radio has all eight conductors available to it no different than running six cables for six radios.

Re: [WISPA] Easy Ethernet up the tower
It is not that simple it matter which pairs you use. If you just try matching wires or pairs at each end you will have problems. You need to punch it down according to the standard or you will not end up with 6 working Ethernet cables. For short runs you could probably get away with not following the standard but don't try it for long runs.

Re: [WISPA] Easy Ethernet up the tower
We don't do this, as we have radios at various heights on the tower. Here is an example of our antennas being at different heights: http://www.f64.nu/gallery2007/view_photo.php?full=1set_albumName=album128id=DSC2218 This uses mostly coax except for hoz antenna on a standoff which uses cat5 up the tower, but you get the idea. Vertical separation is good. I can't really imagine running a conduit, putting in a 25pr, installling a cabinet at height, punchdown blocks, etc... is that much easier than just strapping on a cat5 when you need to install something. If you're going to having a junction box up high, that generally means to me putting cat5 in between the radio and the junction box and putting rj45 connectors on while strapped to the tower in a swift cold wind. We generally put together the cable end on the ground, send it up with the climber, and when it's in place, we chop it from the spool on the ground and do the ground termination on the ground. The climber fastens the rest of it to the tower as he descends.
