This paper provides a simple techno-economic study of various access network technologies for broadband data service delivery, including their deployment cost analysis. This paper compares the deployment cost per unit bandwidth of different access technologies from a city perspective and can serve as a guideline for future access network deployment in the urban area. Optical backbone networks have experienced a significant increase in capacity. Data can be carried at Tbps bandwidth across long distances. However, carrying information to the residential customer still depends on legacy low-bandwidth access networks.
