Necessary to use SFTP UTP for a residential install?

[Muttley]

Hi guys,

I need to install a few AP's at a residential site for a client.

Planning on running CAT5e in the ceiling void and then placing the AP's on the ceiling boards. Question is, is it necessary to use SFTP UTP or will regular UTP be ok?



Many thanks

UTP has a balanced signal and twisted, so in a domestic situation (and most offices) it is sufficient against EMI. Plus you don't have capacitance issues.

Necessary - well, that depends on which version of necessary you're looking at and, for me at least, I consider two:
- for basic networking: pretty much no, (you likely know) you're good up to 100m (at least for signal run, PoE can change things)
- for EMI - for storm EMI ...so lightning, that gets to be a different question which may not be as simple to answer. And as you're doing this Jozi side (as opposed to a mile lower down at the coast), this may apply to you.

I've got some lovely long runs of unshielded UTP in various places around town and if there's one thing they like to be good at, it's being handy inductors for a good localish lightning surge ...not an actual local strike, that just kills everything, but directly above at least.

And at three sites - two in neighbouring valleys in Craighall/ ~ Park I lost kit to storm surges until I put in protection. One site has these lovely little Planet lightning arrestor boxen, and in the last 4-5 years I've yet to lose another IP camera/AP, while at the other we just went wireless 'cos of losing switches/(el cheapo) routers and the LAN sockets on machines; the third site is in Parkview where the worst I've had happen is the APs there lost their settings and had to be reprogrammed.

So is s/ftp necessary - maybe not, but if their area is particularly susceptible to storm-induced damage it might be worth thinking about. And, to me at least, endpoint surge arrestors are a definite win; specially for things you are not going to be able to get at easily later.

Hey,

Thanks so much for the feedback...

I'll be using 3 separate POE injectors (3 AP's) with 3 separate cable runs. Longest run will prob be 49 meters. Install is in Sandton so will ask the client if they're prone to lightening hits.
If need be, I'll get hold of a co that sells those Planet devices.

Thanks once again

So the PoE bricks that come with the APs? Which are mostly fine, yes (we should (be able to) assume that the manufacturer knows what they're doing...); just not bok for one of those on that long run, but why not check it out, hey?

That would be Cable Applications. Or, because those things are ...not the cheapest in town (but they're great (my longest-serving are > five years now)), I've been wondering about trying these Ubiquiti units ...all hidden in a ceiling void, why not, you know?

I only use the Ubiquiti AP's so yeah, I would be using the included POE's and I would assume that they know what they're doing

Thanks for the link, I'll also check out the ones from scoop.

May as well run cat6 for better future proofing as well

Wel-l-l-l ...seeing as Cat5e is good for GbE, at least in a home context and he's talking about runs for APs here, would 'future-proofing' apply? Besides which Cat6 is beyond horrible to deal with (and please not when there's conduit involved!)

Really think it's necessary for a family home with a 20 meg fibre line?
