Hi all,

I am currently researching options for a new access point in my apartment. I would like it to be power over ethernet (PoE) capable so I am able to put it in an odd place with no AC outlet nearby. I'd also like for it to support simultaneous IEEE 802.11 G and N connections.

I have seen a product from Cisco; the Aironet 1140 (http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps10092/datasheet_c78-502793.html).

I have no idea what kind of price these things would be, but knowing Cisco gear, probably more than anyone would want to pay.

Does anyone have any suggestions for alternate options? PoE is definitely preferable as I would rather not have to contract an electrician to add an outlet.

You can really choose from any AP or router out there, there is no requirement to get a PoE one. You can make your own passive PoE splitter for a few $ or buy them premade for not much more, allowing you to use the supplied plug pack and run DC over pairs 4/5 and 7/8

My pick of AP's at present is probably the Ubiquiti AP N's

Hmm, interesting. What would I look for in a pre-made PoE splitter and where do I find them? Could I run cable from my switch (HP ProCurve) directly to the AP and provide power and network connectivity?

+1 for Ubiquity, however as steve pointed out they use a hand made style of POE, out of the box they come with a Power supply with power injection with lan and radio ports, so plug you switch into the lan side, radio into the other, and 230V into the power port. If you procurve has builtin POE then you will need a special adaptor to drive a Ubuqity radio, the local agent has them also.

FYI the Power AP N's are actually just a standard 12V DC plugpack, they aren't passive PoE like every other UBNT device.

To see what I mean by a PoE injector/splitter just have a look on Google. Essentially you just have a small device with two RJ45 ports and DC input and one at the other end with two RJ45 ports and a DC plug for output. You're simply joining the DC supply at one end and splitting it out at the other end.

Note that you'll only get 10/100 over a cat5 that has power down it.

So I'd be looking for a device similar to this: http://pricespy.co.nz/product.php?p=507611

If I were to run CAT6 cable would I be able to receive a 1gbit/s connection? Hardly necessary for my wireless traffic now but in the future with more N capable devices...

Many thanks for all of your assistance :D

Nope. The power goes over some of the pairs, you need all of the pairs to do 1gbit

Have to have proper center tapped magnetics to do power over the same pair as data, and you cant do that midspan which is why all the addon power devices use the spare pairs.

POE means business, and that means they can charge whatever the hell they like. Is pulling a second cable to just pass the DC down an option if really need gigabit?
