Rohde & Schwarz is addressing the demands for characterizing wideband components and systems with the R&S FSW-B5000 option, which will be demonstrated for the first time to at EDI CON USA in Boston.

A year or two ago, it was thought that the first 5G applications would be sub 6 GHz using technologies such as massive MIMO, high orders of carrier aggregation, heterogeneous networks, etc., to achieve better data rates, latency and capacity. But new semiconductor processes and architectures have rapidly progressed making 5G mmWave technology available today at reasonable costs.

Anokiwave, Inc. has completed a Series C funding round led by a new investor, Gefinor Capital with US Boston Capital Corporation and its affiliate Pear Tree Partners. The funding will support the development of silicon-based RFICs for 5G, satellite communications and aerospace and defense markets.

In 5G trials in Beijing, Huawei achieved data rates greater than 20 Gbps using 200 MHz bandwidth at 4.9 GHz.

Movandi, a venture-backed startup with a mission to revolutionize millimeter wave networks announced BeamX technology, a scalable RF front-end system solution. The high performance of Movandi’s RFIC, phased array antenna and beamforming techniques enable the next generation of 5G and multi-gigabit connectivity that will drive new applications.

SK Telecom announced that it, together with Nokia, has successfully reduced latency between the handset and base station to 2 milliseconds (ms) over its LTE network.

Earl Lum, founder and president of EJL Wireless Research, believes the migration to 4.5G and 5G will create a “period of prosperity” for the compound semiconductor industry, as LDMOS power amplifiers cede share to GaN and GaAs. He forecasts that 5G and fixed wireless access transceivers at 28 GHz will exceed 20 million units by 2021, and 5G new radio (NR) transceiver shipments will represent 80 percent of all macrocell shipments by 2021.

Guzik Technical Enterprises announced a new series of AXIe modular digitizers with combined signal processors, the ADP7000 series, for the emerging 5G communications test market and related applications.

Ericsson has launched three small cell products: a multi-operator Dot, a multi-Dot enclosure for indoor deployment and, for outdoor deployments, a strand-mounted enclosure to hold multiple small cell radios.

AT&T said that it is expanding its 5G trials to include three new U.S. cities by the end of the year as part of its push to develop a next-generation network.
