REUTERS/Aly Song/File Photo (Reuters) - Semiconductor firm Xilinx Inc and telecommunications software firm Mavenir Inc said on Tuesday they have partnered to boost cellphone tower capacity for an emerging category of open 5G networks. In previous generations of networks, carriers purchased hardware and software as an integrated package from suppliers such as Nokia, Ericcson or China’s Huawei Technologies Co Ltd. But U.S. sanctions on Huawei have disrupted its business and sped up a move toward what are known as open radio access networks, where carriers can purchase hardware and software from a variety of different vendors such as Xilinx and Mavenir. That allows carriers to save costs and, in some countries, source more parts of their networks domestically.
