28GHz SDR targets 3GPP & Verizon 5G

National Instruments, NI has announced a series of 28 GHz radio heads for the mmWave Transceiver System. This combination creates a full transceiver that can transmit and/or receive wide-bandwidth signals of up to 2 GHz of bandwidth in real time, covering spectrum from 27.5 GHz to 29.5 GHz.

The mmWave Transceiver System software defined radio (SDR) and application-specific software offer a complete and comprehensive starting point for 5G measurement and research addressing both the 3GPP and Verizon 5G specifications.

The mmWave Transceiver System can operate as either an access point or user device in any over-the-air testing scenario. Users can also develop mmWave communication prototyping systems or perform channel measurements – necessary exercises for wireless researchers to understand the characteristics of a new spectrum – using the same system. The software works with the previously released radio heads for 71–76 GHz, so users can easily adapt their mmWave Transceiver System to 28 GHz by changing the RF radio heads.

Additionally, the mmWave Transceiver System baseband software delivers a complete communications physical layer compatible with the proposed 3GPP and Verizon 5G specifications as source code for LabVIEW system design software. This helps expedite system development by delivering a ready-to-run system that users can modify to adapt to their specific areas of research or testing.

“The new 28 GHz mmWave Transceiver System has been a key technology for many participants in our RF/Communications lead user program,” said James Kimery, director of RF research and SDR marketing at NI. “As the world allocates spectrum for 5G, 28 GHz has emerged as a leading candidate for several countries including the United States, South Korea, and Japan.”

Next Generation Freight Transport Mark Patrick | mouser Electronics
Next Generation Freight Transport
As road freight transport levels continue to grow, concerns about the impact on the environment and human health come sharply into focus. Fossil fuel dependency makes it a leading source of greenhouse gas (GHG) emissions, but shifting freight to other transportation modes will prove challenging. Solutions that will improve the efficiency and performance of road freight transport are therefore essential to achieve defined environmental goals. In this blog, we will explore a potential solution that has been pioneered by Siemens - called eHighway. This combines the efficiency of electrified railways with the flexibility of trucks in order to form an innovative, next generation freight traffic system that is efficient, economical and environmentally friendly.
