Open RAN Direct RF Sampling Radio Transceiver Architectures For Massive MIMO


With the exponential increase in wireless traffic, mobile networks are transformed into more software-driven, virtualized, flexible, intelligent, and energy efficient systems. These trends have stimulated significant change in the core network with the advent of software defined networks (SDN) and network functions virtualization (NFV), which have enabled building more agile and less expensive ... » read more

5G Brings New Verification Challenges


In the summer of 2018, Siemens raised a few eyebrows within the verification community when we acquired Sarokal, based in Finland. What that community did not piece together at the time was that Sarokal is the leader in 5G testing and has a seasoned team of people that have work closely with leading telecommunication companies to provide hardware and software solutions for fronthaul system test... » read more

5G Needs Cohesive Pre- And Post-Silicon Verification


While 5G doesn’t start from a clean slate, it does make significant changes to the 4G architecture. These changes mean that the ecosystem from chips to operators is evolving, giving opportunities to more companies to engage in this growing market. Realignment in fronthaul, midhaul and backhaul In particular, the radio access network (RAN) has been redefined as Cloud RAN (sometimes called ... » read more

5G Wireless Infrastructure Pushes High-Speed SerDes Protocols


5G is the 5th generation wireless system standard that, through high speeds and increased accessibility, promises to change the way we stream, communicate, work, and travel. Boasting speed capabilities of 20Gbps and network densities of 1 million connected devices per square kilometer, 5G is the required technology for the implementation of highly anticipated technologies like autonomous vehicl... » read more
