One of your customers plans on providing wireless coverage to a warehouse facility. After performing an initial walkthrough, you collect the following information:
The central part of the warehouse is between 400 and 600 feet (122 to 183 meters) from the warehouse switches mounted on the walls.

✑ The warehouse storage is composed of metallic racks with varying inventory levels and contents, from electronics and plastic toys to food pallets and juice bottles.
✑ Workers need basic data coverage from their working location, and are not highly mobile. They usually work from one single aisle, and their laptop is on a cart with wheels.
What would be your one recommendation to provide coverage to the central area of the warehouse?
