Bob, does the 100,000 sqft warehouse they rent have a high ceiling or low? What obstacles are in the way? Shelves made of metal that block full of contents, etc? Can they mount the unit high and is there power receptacles or a catwalk that could easily be accessed to reset/remove/place the unit? How many total devices/clients would be on the wireless (by your description it sounds light duty)? What is the budget? Would they be able to afford multiple units if the warehouse was densely populated with product/etc, possibly mesh a few to the LTE unit if needed?
Can you post a picture of the warehouse inside. Is it more like the first picture or second? Thanks!
