SMI WiFi is a custom integration company that specializes in installing and managing WiFi networks in large commercial buildings like hotels, medical buildings, and apartment complexes. They work with property managers to survey the building, install the necessary equipment, and set up ongoing network management. SMI WiFi then leases the network to the property owners, who can provide WiFi access to customers. This generates revenue for both SMI WiFi and the property owners while providing a more affordable and customizable WiFi solution than traditional internet service providers.
