A Business Case for the Deployment of a 4G Wireless Heterogeneous Network in Spain

The emergence of wireless packet-switched networks such as UMTS, WLAN and WiMAX allows the introduction of innovative services and opens up a new range of revenues. It is considered that 4G wireless networks could be heterogeneous networks with different access technologies. Moreover, the introduction of the IMS (IP Multimedia Subsystem) in the core network of packet-switched networks permits a rapid provisioning of new services. The main objective of this paper is to determine the feasibility of a 4G wireless heterogeneous network in Spain. An urban zone and a rural zone were considered in the study.
