Twisted pair has a remarkably high CMRR.  I can't imagine that Cat5e and later has appreciable emissions that could induce from one STP to another.

In a rack with V50 receivers and a router it's probably a very good idea.  Seems I saw that on a thread on PSW Scott.

You can definitely tell from a V50 scan if there are unshielded network cables in the same rack.  Shure recommends shielded cables and that's what they include with their receivers.

The only caveat to this I can think of is that if neither device grounds the connector shell then the shield will float, which has the potential to can cause all sorts of issues.

It's a big antenna at that point I believe.

The biggest disadvantages of shielded cable are cost, rigidity, fragility, and weight, and for most Ethernet applications the advantages are pretty nominal. IIRC, Ubiquiti encourages shielded cable for their APs because it offers increased protection against lightning-strike damage, but if that's something you're worried about then I'm guessing you're going to have bigger challenges than your AP.

That all said, given that at least one end of the cable run is properly grounded, you aren't going to make things worse by using shielded Ethernet cable (if you're reusing stuff you have lying around, for example), but for most applications I wouldn't suggest going out of your way to do so.

I thought Ubiquiti recommends shielded cable for AP's because they are mounted in ceilings which are high RF environments. 


We did a wifi installation at a new hospital for Cisco.  They required all of the AP's to be fed by cable in EMT and mounted to metal boxes. That was a very hostel RF environment. 


On an interesting note this is a Vocera device used mostly in healthcare.  Full duplex sip phone, connects to voice recongnition servers on back end to control all sorts of functions like scheduling transport, MRI, pharmacy robot (delivers the meds) it was amazing, weighs a few ounces and you wear it like a security badge.

I can't speak for Cisco (although I have no doubt that a hospital would be an extremely challenging RF environment), but the datasheet for Ubiquiti's TOUGHCable only mentions protecting against ESD damage (and nothing about RF interference).

Now I need to fire up the grill...

Shielded potato?  Twisted pair asparagus with garlic and olive oil?

Back to the question posed in the topic:  the higher rated twisted pair cables are shielded.  IMSHO, plan on everything being shielded whether CAT5e, CAT6, CAT7... CAT96.  I personally like to keep all that digi-hash inside the tube, thankyouverymuch.

Yep, it's simply the best practice if nothing else and if operating wireless systems...well....

MMM Garlic and butter brushed grilled asparagus  yummmm
