Anritsu Company has released call-based LTE advanced carrier aggregation testing capability for its MD8430A LTE signaling tester. The software-only upgrade leverages the four available frequencies in the MD8430A, and provides 300 MB/s downlink throughput using two 2x2 MIMO component carriers (CCs). When configured with this option, the MD8430A can test advanced wireless devices at twice the rate available on today’s most advanced LTE networks.
The LTE Carrier Aggregation option for the MD8430A is available now for testing LTE Category 6 wireless devices. The MD8430A LTE signaling tester is capable of simulating up to six LTE eNode Bs with up to four frequencies. A variety of MIMO modes are available, including simulation of four SISO, two 2x2 MIMO, or one 4x2 MIMO downlink.
The MD8430A is also the central component of Anritsu’s ME7834L LTE Mobile Device Test and the ME7873L LTE RF/RRM Conformance (RFCT) test systems. The ME7834L provides both protocol conformance test (PCT) and carrier acceptance test (CAT) protocol capability, and the ME7873L supports both RF conformance and RF supplementary (CAT) tests. Anritsu supports the industry’s largest number of validated PCT and RFCT test cases available.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
