POE (Power Over Eithernet)

I have a small school library that I want to put a WIFI signal in. I
want to use POE.

Has anyone used any POE devices and can they recomend which ones to
use. Im also wondering about having a POE access point rather than a
Router, eg why ad another router that will just have to be set up etc.
rather than an access point that negotiates with an existing router.
(if you can do that with POE)

Any advice ?

thanks.

Thanks I will look at those.

Especially if you don't mind spending $1,500 dollars! You are trying
to simplify, therefore need to install a $1000 switch to get POE? I
think you can buy a POE injector/splitter combo for far less and then
just use a consumer grade router.

I don't know squat about POE, but here's once place that has injectors
etc.

Yes well I would like to get the best but I dont have 1500 dollar
budget for this. I tried looking for the Cisco unit but sadly I could
not find it locally. I asume it is a high end product. It was my
mistake however since I didnt quote how much I would like to spend. I
would say around 200 dollars. The fact that I didnt get too many
responses may mean that few have use these. Frankly when I walk into 5
out of 5 stores so far none have had or even know about poe. They all
seem to have power through the wall socket type units. eg it sends the
signal through the wall socket. Reverse of POE. These may? be good
units I dont know. I wonder if anyone has had any experience on
these ??

Steve, I've used both 11mb and 85mb units (based on the HomePlug spec) which
bridge over the house wiring... primarily due to the fact that my
son-in-law's house has foil covered insulation in most of the floors (wifi
was a miserable failure between floors).

These units have worked very well for me, good bandwidth. I have one
plugged into the broadband router, one travels with the house desktop
wherever it may be at any given time, and one travels with their laptop all
around the house, yard, wherever.

Aaron; it seems like you do have experience with POE, so I'm
wondering-

why you suggest a switch instead of an injector? In case he has to
install more than one AP?
similarly, is a splitter not as good as an actual POE powered AP? Or
is it just the elegance factor?

Otherwise, I'd think that $50-60 for an injector and splitter combo,
and then $60 for a Linksys WRT54GL (DD-WRT) would be a very cheap
solution. Oh, I see that Steve prefers less setup, so get a dedicated
AP/Client, same cost.

Again, I don't know squat, but how complicated can it be? It's just a
matter of breaking out a couple of wires and feeding them DC, right?

Steve: I have an installation with an ethernet client (same thing-
could be AP) up on pole in a rootenna box. Instead of POE, I just
ran some 16 ga. zip cord spliced it into the power supply cord for
the 30 feet I needed to run power. I did not do any voltage loss
calcs, but it's for an older Linksys WRT54G which I understand has a
wide range voltage tolerance. Works fine, of course.

Yes, I had to zip-tie two cables instead of one to the post, but so
what?


I'm sure there are shortcomings to this that aren't evident in my
application, but it might work for you as well.

Following a thread on Ubiquity products, I found this new AP/client
station which may be just what you are looking for:

http://www.wirelessnetworkproducts.c...OD&ProdID=1891


It comes with a power injector included.

Supposedly, this is a quality company that is a notch above consumer
grade. It includes a fairly wide angle directional antenna, so this
unit could work for you if you could install it high in a corner to
cover your library.

Seems like the perfect solution. You could buy two and stay under
budget !
