Selling my BE17000 and 7 BE10000 systems as I have changed over to Ubiquiti products. As depicted in the pictures, the BE17000 is a set of three and the BE10000 is a set of four. The links provided below should provide all the information you need. These are great mesh systems, but I need a system designed with greater web management from remote location. Price is firm.

I may break up sets if you only need one or two. These systems are interchangeable and can be used with each other.
