        I did that and it came up with 7' in the middle, but seemed like closer to the device you don't need that much room for the signal. Am I understanding that correctly?

          That's the way it looks to me, like the signal gets wider in the middle and tapers at the ends.

              I would never shoot wireless point to point through a mall like that. There is no way you can guarantee that the space will not get blocked come holiday season, etc.

                I agree, run fiber and you won't regret it.

                  Yeah, it's indoors. You own the space (or the customer does), why resort to wireless?

                    The fiber run would involve roof penetrations and protecting the cable on the roof. I'm going to get a price, but it would likely cost way more than two Nano Beams and two hours of my labor.

                      No provision to run more wires, that's an architect I'd have a few words with/for.

                        I don't think that's fair. They didn't have network cabling back when these buildings were built.

                        If you consider a residential house, just as fast as people started running network cables to the backs of TVs, manufactures started building in wifi adapters that make the network cable unneeded. Right now people are putting in conduit between their entertainment center and the back of their wall mounted TV for all the cables. 5 years from now we'll probably have a wireless HDMI cable that will make that obsolete.

                          We'll agree to disagree on that then.

                          That said, I do think your wireless option should work.
