Need ballpark range estimate

[Nathan Spitzer]

I have been tasked with getting an estimate for deploying wireless in a to-be-renovated space and I would just like a sanity-check WAG/best guess as to how many AP's to deploy.

The new space is 85,000 square feet and will be a standard Dilbert "cube farm" with a few enclosed conference rooms. There are no elevator banks or other big, hard, obstructions in the space. In the initial design there will be a coffee-bar/break-room type area in the very center so thats where you will find refridgerators, microwaves, etc. Its dimensions are roughly square about 290 feet a side.  Pulling a number out of my head (and off a Cisco document), if I were to say I wanted at least 48Mb/s connection speed on the 5Ghz band, how many 3502i Ap's would be reasonable? Based on a Cisco document I would guestimate I could get that from placing them about 75 feet apart to allow for overlap and from that derive that I want 16 AP's, each about 75 feet apart. Does that sound reasanable as a budgetary WAG where I cannot do a site survey?

Thanks

Having deployed a great deal of WiFi over the years. The process to budget is pretty simple.

Data - sq feet / 6,500

Voice -  sq feet / 2,500

These are conservative numbers.

I hope this helps

poking around I come up with

Data -sq feet / 5000 17 AP total

Voice - sq feet / 3500 25 AP total.

These are just estimates and should not be taken for truth.

HTH,
Steve

Thanks guys, so it looks like my estimate of 16 is in the right ballpark.
