Question: Which is better? Throttle the cpe at the cpe or at the router?
Currently we have a router setup at each tower site and do bandwidth limiting
on it with simple queues and the users ip. But we want to setup our billing
system so the office help can change packages and we just have it
For 802.11 systems, I prefer to split it.
I limit D/L, from internet to client, at the border router.
This allows the limiting to be done before the traffic enters my
wireless network, reducing congestion and load on my backhauls
I limit U/L, from client to internet, at the cpe.
This helps
Though it looks black in the picture, normally it is bare copper or bare
tinned copper.
It touches the shield all along the cable and is used to drain the
electrons to ground. You have to strip the jacket back a little farther
than non-shielded cable to have some drain wire to work with.

There are clamps designed specifically for cable with no drain wire.
But I can't find the ones I used for BDDN cable right now.

We throttle at the CPE where we have the ability. Our reasoning is that the
less traffic there is hitting the AP, the more users we can put on it, and
the better experience everyone has.

queuing and delaying the user's uplink requests/acks since managing
the actual download traffic would involve dropping packets or queuing

Got news for ya, STP does not fix the problem - the problem is with the

If you are using plastic RJ45 with STP then you are wasting your time and

While we are on the STP topic... It's been noted several times that you
are only supposed to ground ONE end of the STP shield otherwise you are
creating for yourself a ground potential difference. The idea behind the
shield is just that - shield noise away shunted to ground. On a typical

Link Technologies,
If you don't ground both ends you're creating a huge antenna to pick up
static and drain it right into your board/POE.
Always use shielded connectors on both ends, and ground both ends.

It did for us, but we always ensure a good electrical ground from end to

connector isn't making a good connection to the plug, etc.

That should always be done at the CPE. Otherwise your over the air traffic
stays high as devices keep trying to shove traffic through too small
ports.

From way back when I was an electrical engineering student, ground one
end. Or ground every 10 to 20 feet along the run. Otherwise you have
the potential for a ground loop, which means you have current running
through the shield and then through the tower. That can induce it's own
noise

So do you solder or ground the shielded end at any point or just ground

Well what are you grounding on either end? At the base of the tower
you actually go to earth - the radio itself isn't ground - the earth

I guess the best thing to keep in mind is... do whatever works for you.
If you're talking tower:
We ground at both ends, because the ground potential is the same at both
ends (i.e. the tower, the building DC/AC source, routers, switches, etc. are
all tied to a common ground).
