  • Patent number: 8989816
    Abstract: It is disclosed a node of a radio access network. The node comprises an access device having a transceiver suitable for exchanging upstream and downstream traffic with a plurality of terminals located in a coverage area thereof, a digital unit suitable for performing base-band processing of the upstream and downstream traffic, and a traffic link connecting the transceiver and the digital unit. The node further comprises a backhauling apparatus having an outdoor unit suitable for exchanging the upstream and downstream traffic with a further node of the radio access network by means of a point-to-point microwave connection. The transceiver is connected to the outdoor unit by means of a backhauling link. The digital unit of the access device and the outdoor unit of the backhauling apparatus are configured to exchange the upstream and downstream traffic through the traffic link, the transceiver and the backhauling link.

  • Patent number: 8627064
    Abstract: An infrastructure is provided for managing the distribution of digital certificates for network security in wireless backhaul networks. In embodiments, a root certificate management system (root CMS) processes requests for digital certificates, issues root certificates, automatically authenticates surrogate certificate management systems (sur-CMSs), and automatically processes certificate requests and issues certificate bundles to sur-CMSs that are successfully authenticated. The infrastructure includes sur-CMSs to which are assigned base stations within respective regions. Each sur-CMS automatically authenticates its own base stations and automatically processes certificate requests and issues certificate bundles to base stations that are successfully authenticated. A certificate bundle issued to a base station includes a digital certificate, signed by the issuing sur-CMS, of a public key of such base station, and at least one further digital certificate, including a self-signed certificate of the root CMS.
