Mavenir, in collaboration with MTI, Facebook, and Vodafone, recently led the lab validation of the first-generation Evenstar RAN product, demonstrating the Evenstar RRU in an OpenRAN lab setting interoperating with a DU solution over 7.2 interface. The next challenge is to validate its performance in the field, with live network nodes carrying commercial traffic.\u00a0<\/span><\/p>\n<p><span>With this lab validation complete, we expect the second-generation Evenstar RRU to be available in mid-2021. As we near completion of the RRU product portfolio, the DU project is now underway for both standard and merchant silicon\u2013based configurations. We are collaborating with key silicon component providers to develop products that will further increase efficiencies around cost, size, and power for RAN components.\u00a0<\/span><\/p>\n<h2><b>What\u2019s next for Evenstar?<\/b><\/h2>\n<p><span>We expect field trials and scaled deployments for OpenRAN to significantly accelerate in 2021, with Evenstar playing an important role in helping reduce costs and increase flexibility and component-level efficiency for operators globally. Once the first components become available, we believe operators will see firsthand the benefits that Evenstar offers. Our hope is that early positive experiences will lead to greater commercial adoption of these initial products which will, in turn, help expand the network of OpenRAN suppliers. Through Evenstar, we intend to drive disruptive technology innovations to keep OpenRAN competitive in the long term and provide operators with more options.<\/span><\/p>\n<p>The post <a rel=\"nofollow\" href=\"https:\/\/engineering.fb.com\/2020\/12\/17\/connectivity\/evenstar\/\">Evenstar: The road to an alternative infra supply chain for RAN<\/a> appeared first on <a rel=\"nofollow\" href=\"https:\/\/engineering.fb.com\/\">Facebook Engineering<\/a>.<\/p>\n<p><a href=\"https:\/\/engineering.fb.com\/2020\/12\/17\/connectivity\/evenstar\/\" target=\"_blank\" rel=\"noopener\">Read More<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Together with mobile network operators Airtel and Vodafone, and technology partners ADI, Altiostar, Baicells, Flex, Mavenir, MTI, Parallel Wireless, and Xilinx, we are focused on building general-purpose radio access network (RAN) reference designs for 4G and 5G networks in the Open RAN ecosystem.\u00a0 This work is being done as part of the Evenstar program.
