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.
