I've got an airport extreme base station. Seems to cover about 250 ft. (down a long hall) I've got another 750-1000 ft that I'd like to extend wireless coverage to (essentially another hall -- one floor and an open mezzanine) My understanding is that I can "chain" airport express stations that simply plug into a 120v outlet to extend coverage. Can anyone point me in the direct of a discussion or FAQ or the like on this? Maybe there's a less expensive way to do this. But I'd like to be able to have ipad and ipod touch and some iphone connected to my network. It's a warehouse type environment. My idea is to have little ipod touch's set up to take photos of product leaving the warehouse (for backup/insurance freight purposes) and it would seem efficient if I could take the photos and then have them upload to iCloud.
PS. I've also got a separate setup in my house that the airport express is the main station. That works for a couple of rooms and I'd like to be able to "extend" it a couple of more, so am interested in this idea of airport "chaining" if indeed that's the correct term.
