The retail gives free WiFi connection in their premises, but if the SSID carries your brand name, it should be serve in the best way possible.
The client ask for a complete assessment of the WiFi coverage and the evaluate the deployment of the network. Review architecture and other elements in the network that may affect the service delivered to the shopping mall customers.
First, understand the deployment and the architecture, evaluate 3rd party software, and finally, perform a “walk” test into the shopping mall to generate a coverage and noise map.
We use a portable 3G/WiFi router connected to laptop solutions and others connected to fixed probes into interest points. After a period of measures we finally present a report of coverage, best practices, a list of change proposals and a revision fo the architecture (captive portal). The result was a sustancial improvement in the quality of service delivered to the shopping mall customers.
