Service development in a multicast hybrid wireless environment [articol]

Abstract

This paper presents an architecture that tests the capabilities and potentialities of interworking between the DVB-T and WiMAX technologies in order to create an infrastructure that provides capabilities for multi-service development, using a single access physical infrastructure shared by multiple services. The present work describes the developed hybrid communications access network that use a regenerative DVB-T framework for enabling/ permitting/ promoting/ accepting different kind of providers to become co-equal users of the same infrastructure, through which they access (or provide) broadband connectivity to Internet for a large category of users. Based on this structure, a specific testbed has been implemented at University “Politehnica” of Bucharest using the interoperability capabilities of the 802.16d WMAN (WiMax) and DVBT. This work presents the specific aspects of the testbed implemetation and a number of tools and applications developed and tested.
