"Speaking as an \r\n\r\nAmateur\r\n\r\n Extra class ham operator.\r\n\r\n1.) A single extremely high powered WAP to cover the entirety of the warehouse. (Some up to 50-60k Sqft)\r\n\r\nWell I guess we are throwing FCC regulations out the window.  :)Seriously, remember WiFi is two way communication, so not only does the end device have to hear the WAP it must also be able to transmit to the WAP.  This will not work in a 30K square foot facility. \r\n\r\n2.) A single WAP with external antennas placed all over the warehouse.\r\n\r\nThere are some big potential issues with this as well.  One WAP with multiple antennas widely spaced will result in garbled data.  You will have different delays based on length of cable, SWR (Standing Wave Ratio), which is power reflected back due to poor antenna / cable matching, and a host of other issues as well.How many devices need to communicate via WiFi?How much data?What material is stored in the warehouse and how (metal racks 20' tall, vs pallets on the floor)?How is the warehouse laid out?Any electrical or RF interference in the space?What radio bands are needed (2.4G 5G)You have the right idea, but the correct solution will depend on the above questions and more.  Hire a company to do a survey of the site and they will be able to tell you what you need and where to put it.  You can take that data and do some comparisons and make an educated decision rather than throwing ideas and money at it to see if something works.  That site survey would probably be money very well spent since neither the owner or you are experts in RF.  :)"
