The Advanced Broadband Communications Center (CCABA) is located at the D4 building of the Campus Nord  in Barcelona. The research laboratory has been designed to interconnect research laboratories of the Broadband Communications (CBA), the Broadband Networks (BAMPLA), the Optical Communications (GCO) and the Radio Communications (GCM) groups in order to provide a network platform where researchers can collaborate with each other. The laboratory has an direct connection to the Academic Network  (CESCA / RedIRIS) with a 1 Gigabit Ethernet link. This connection is used for experimentation and for the connection with other European testbeds and for supporting research projects on networking. A dedicated connection between this laboratory at building D4 and the one located in the Neàpolis building is provisioned through the UPC network.
