I discuss experiences in the development of four broadband public networking projects in New York State in order to see an implication for future small or medium-sized enterprise over such public networks. The projects were funded under a state program to diffuse broadband/advanced telecommunication technologies in economically depressed areas of the state. Through the broadband networks, I critically argue characterization of next generation public network (NGPN) in reference to small medium-sized enterprises (SMEs). I identify several facets of an NGPN drawing on a longitudinal study of the network development in four New York communities. As broadband public networks diffuse, small businesses being left out of the loop. The idea of SME application and service may itself be at risk. My approach to the socio-technical challenges involved in the design and development of broadband public networks is outlined.
