Abstract: A scheme for providing access to 6LoWPAN data in a wireless access network comprising a Digital Unit (DU) coupled to one or more Radio Units (RU) via CPRI links, each RU in turn coupled to one or more radio dot (RD) elements via Ethernet cable links. In one embodiment, an RD element includes a cable front-end interfaced with the Ethernet cable link, a radio front-end interfaced between the cable front-end and an antenna or a suitable access point. A sensor component may be included that is configured to generate sensor data with respect to a measurement variable, which sensor data may be packaged in a 6LoWPAN data format for transmission to the RU element coupled to the RD element.

Abstract: A scheme for providing access to 6LoWPAN data in a wireless access network. In one embodiment, a Radio Unit (RU) of the access network is provided with IP bridging functionality for packaging 6LO data as a control channel message. When the RU element receives 6LO data from an external router, the data is packaged in a format specified for a control channel associated with an Ethernet cable link coupling the RU element to a 6LO endpoint of the access network. The bridging functionality is operative to transmit the control channel message (including the packaged 6LO data packets) to the 6LO endpoint based on an address mapping between the destination IP address of the 6LO data packets and the 6LO endpoint' s address.

Abstract: A scheme for providing access to 6L0WPAN data in a Pico-Remote Radio Unit (PRRU)-based wireless access network. In one embodiment, the PRRU network comprises a Baseband Unit (BBU) coupled to one or more remote Radio Hub (RHUB) elements via a first set of CPRI links, each RHUB element in turn coupled to one or more PRRU elements via corresponding second sets of CPRI links. The BBU element comprises an interface for communicating 6L0WPAN data to and from a router coupled to an IPv6 network. The BBU element also includes a bridging functionality operative to determine endpoint PRRU elements' addresses and corresponding RHUB elements' addresses by querying an address mapping database.
