Indoor Wireless Networking Configuration

I have an small office building with three floors whose dimensions are 100' x200'.  The building is rectangular and has a courtyard in the middle. Therefore passing through brick is a consideration. The construction of this older office building is wood and plaster or beaver board.  I have a laptop that I want to take from location to location within this building.  Also, a few managers require access to the Internet from their offices.  I would like to setup Internet Access to every office although it may not be used.

My plan is to use the components listed below:

2      Linksys Wireless-G Broadband Router w\ SpeedBooster  WAP54GS

1      Linksys Wireless-G Notebook Adapter w\ SpeedBooster  WPC54GS-CU (PCMCIA Card)

I use WPA-PSK for security at home and plan to use it at my office.

The DSL Line will be located in my office which faces the courtyard on the first floor. It is towards the front of the building..  I plan to locate a Range Expander in an office on the second floor of the section across the courtyard from my office towards the rear of the building. As I write this it occurs to me that this is just like putting in a wireless network at an apartment building only no legal conflicts because it’s just my company and I have business DSL service from Verizon.   We recently had to move and this was the best deal I could get. That’s why there is no Ethernet cabling.  Well there but it a total disaster.

Suggestions and comments

Thanks for all your help,

I would suggest you to check wireless coverage in your building before you'll start real installation. You need to make sure all your offices covered with WIFi signal. Also, do not forget about security issues, WEP or any other authentication.

You could pick up this Power Over Ethernet kit, http://www.linksys.com/products/product.asp?grid=36&scid=47&prid=582, and run cabling to a more centralized location in your building to move the signal say 1/3 into the building.  You could put the other one at the 2/3 spot and then put the two on different channels, such as channel 1 and 5.  Then you should, environment aside, get nice coverage.  Pick up one and place it where you think it should go and then walk around with netstumbler http://www.netstumbler.com/downloads/ and analyze your signal strength.

Also, mounting bracket for putting the Linksys up high - in or on the ceiling:  http://www.linksys.com/products/product.asp?grid=36&scid=47&prid=504

Power Over Ethernet is to get electrical power to a device where you're already running Ethernet to the location.  That assumes that you WILL have Cat5/6 to the location of the second AP.

Channels should be chosen to avoid overlap, especially if you want peak performance.  So "1 & 5" would be a poor choice -- you need FOUR unused channels to avoid overlap and {2,3,4} is only three.

PennGwyn, that POE adapter injects power into the ethernet run and then seperates it on the other end.  I dont understand why you say "you're already running Ethernet to the location".  I was telling him he could put his second WAP out in a more centralized location by running POE to it, assuming he would obviously have to pull an Ethernet cable to the location where he puts the WAP.

For the channel 1 and 5 - I don't understand why you're saying those are poor channels to avoid overlap.  He only has two WAPs he's talking about - so channels 1 and 5 are seperated by 3 channels between them!?!?

Solution:
Thanks for all the advice but I found the following solution:

Purchase two  Belkin Pre-N F5D8230-4 Wireless Router.
              http://catalog.belkin.com/IWCatProductPage.process?Merchant_Id=&Product_Id=184316
              http://www.belkin.com/pressroom/reviews/recentArchive.asp?p=1

Run Ethernet from on side of the building to a point in the middle of the other side of the building.

Use MAC address to allow access to the Internet.

It's working fine for 30 users.
