Heterogeneous all-IP wireless broadband with WiMAX, WiFi and HSPA

Wireless network operators often offer wireless broadband services by using different wireless technologies such as WiMAX, WiFi and HSPA. Each wireless technology often uses a separate and stand alone network architecture, and thus operations and management may easily become a complex and expensive task. In this paper we present the design and implementation of an all-IP heterogeneous network where the services provided are public and private wireless broadband access based on Fixed WiMAX, WiFi and HSPA. These basic services and combinations of these are further used to design different commercial products in the network. Radio coverage measurements are then performed for these technologies in interesting parts of the realized deployed network. The overall network implementation has been in successful operation for several months.
