I am looking for an image or chart that basically shows the range that Wireless Access Points cover, reason for this is that we have a 120,000 sq ft facility where I want to make sure there is a strong (depending on cost) wireless signal in the entire building (1 floor). As far as I understand the "rule" is to have 1 Access Point every 300 feet which means that I would need to setup 400 AP's to cover the entire building, but that is to have maximum speeds...with a chart that shows how much the speed decreases the farther that you are from the AP would really help me to present it to my boss...I could use Vision to do it myself but if there is a chart already out there it would make things faster. Thanks!!
