We just installed a ubiquity wireless network for a large premises in Dubbo utilising 3 x unifi ap pro https://www.ubnt.com/unifi/unifi-ap-ac-pro/. The client was having constant problems with WIFI coverage within the building, constant dropouts and slow connections to their edge devices. We used a UNIFI 24 PORT POE switch to ensure the client would get the best possible user experience. Project cost approximately $3000.00
