Small AP with PoE?

Does anyone make a reliable AP with PoE?  I'm about to buy three or
four APs for a client's house, and tucking them into the ceilings
would work best, so I'm looking for something with a
standards-compliant (802.3af) PoE solution.

My fallback is Linksys WAP54G and either the WAPPOE or the WAPPOE12,
anyone know which is the right one?

While I'm at it, how about an 8-port (or so) 10/100{/1000?} switch
with PoE integrated?

Thanks!

Take a look at the Cisco 1100 and 1200 APs

A cisco switch will inject PoE but it's pricey. I'd like to see what
other people suggest.

Not as bad as Cisco, but a decent router (similar code to the 7324 / 7312):

$1200, 24 10/100 + 2 10/100/1000, layer 3 and QoS.  I've played with a
few of them...

Its quite easy to make a Power over Ethernet adaptor.

To construct one, first you must understand how it works. An ethernet
connection DOES NOT REQUIRE 8 PINS. Only 4 pins, or 2 copper pairs in
the 8 core cable are used. On the RJ45 connector, these are pins 1, 2, 3
  & 6. This should be the orange and the green pairs. When you wire
everything up, power shouldn't go near your modular plugs. These are
intended to be data ports only.

I constructed one a while ago for my Linksys WRT54G by cutting the power
lead in half, then wiring each end to an RJ45 modular female type
socket. I wired pins 4 & 5 (blue pair) to the positive rail and pins 7 &
8 (brown pair) to the negative rail. I also purchased a plastic box with
a modular punchout to suit the RJ45 connector for each end, to make it tidy.

From the modular plug on each end I run a short patch lead to the
access point and to a switch inside my home.

Today my WRT54G lives in a sealed enclosure on my roof where its
connected to some external antennas. Power and ethernet is carried over
a 15m CAT5 lead.

Some useful wiring diagrams can be found at
http://www.aptcommunications.com/ncode.htm

Might be worth having a look at google too, I'm sure someone out there
has a page about it.

Making one PoE adapter and prividing neat professional wiring for a
bunch of PoE powered APs is two different things.  The OP says he has
3 APs.  In a DIY approach you works require 3 duplex power outlets
which is frequently a liiting factor.

A pox on power strips.

Disassemble a commercial PoE adaptor and then tell me what you think.

Well, it's quite easy to lash up something that will use the unused
wires in a 10/100 Ethernet drop to probably provide sufficient power
to run certain things, but I'm more interested in 802.3af-compliant
Power Over Ethernet, so I can expand the network in the future with
cameras, APs, night-lights, weather stations, wall-jack switches, and
who knows what all stuff that will be coming out in the future, and
won't destroy anything that inadvertently gets plugged into the wrong
port.

The problem is that 'professional' PoE mid-span injectors seem to be
near $100/port, and PoE peripherals seems to be few and far
between(*).  Maybe I'll go with the Linksys stuff initially and
upgrade incrementally as prices drop.

Thanks for the feedback!

Here's an 8 port injector. I have no idea how much it is or where
to get one.

http://www.poweroverethernet.com/poe/content/view/full/1609/

http://www.poweroverethernet.com seems to be an interesting site.

FWIW, Putting "poe injector" into google comes up with lots of hits.

Pricing for the 24-port Midspans start at $295 in OEM quantities.

That's not bad, though I don't seem to find any actual distribution, a
typical problem with announcements.  I've also found
http://www.l-com.com/jump.jsp?lGen=detail&itemID=9476&itemType=PRODUCT&iProductID=9476
which has a WWWeb interface, and is only $389 for the 12-port.

Turns out Netcom has the WG102 and WG302 APs, though AFAICT the WG302
isn't actually out yet.  D-Link has some gear, but I'm never buying
any more D-Link products.  I've also found the Ortronics Wi-Jack, but
I'm almost afraid to ask for pricing.  8*)

Proxim made a POE server for its wireless APs awhile back. Here is one on
Ebay at this posting time under fifty dollars.

Just a minor note.  The WRT54G is unique in that it has a nifty
switching regulator on the power supply port that will run on any
applied voltage between about 4VDC and 18VDC.  The lower limit is
defined by the 3.3v output dropout voltage.  The upper limit by where
the filter capacitors and regulator get fried.  The nominal 12VDC wall
wart can run the WRT54G through some very very lossy cables and still
work just fine.  Here's a bad photo of my BEFW11S4 (similar regulator
design) running off 3.6VDC.
  http://www.LearnByDestroying.com/pics/drivel/slides/low-volt.html
For simple installation, I don't bother borrowing 4 wires out of the
CAT5 bundle.  It's too big a hassle dealing with the connector
conversions.  I just run a 2nd cable as an extension cord for the
power with whatever cable I can find.  Current favorite is 4 conductor
antenna rotator cable.  Also, be sure to add an inline fuse at the
wall wart of idiot protection.

I'm not sure what other products have such wide range regulators.  The
easiest way is to just try it.  Power the access point or router with
an adjustable power supply, and see how low you can go before it stops
working.
