1) Many cities have tried implementing city-wide Wi-Fi networks but with mixed success, as the networks are expensive to build and maintain and often do not offer clear advantages over existing broadband options. 2) Case studies of Wi-Fi networks in Chicago and Philadelphia showed the networks faced ballooning budgets, slower-than-expected subscriber growth, and falling broadband prices that reduced demand. 3) Hong Kong has opted for a partnership approach between government and private ISPs to provide public Wi-Fi access points, avoiding large public financing burdens while allowing private sector involvement. Security concerns remain for users of public wireless networks.
