Certify your 450 MHz IoT devices

Redding Traiger — Thu, 06 Jun 2024 21:59:16 +0000

The Global Certification Forum (GCF) announced that it is adding certification for devices using 450 MHz bands. This will enable compliance with the highest quality and interoperability requirements for devices operating in the 400 to 450 MHz spectrum range, with LTE bands B31 and B72 initially in scope. Cellular bands in this spectrum range are becoming the…

5G is much more than cell phones. IoT devices, medical devices, and industrial devices can connect to networks using technologies such as TDD, network slicing, and beamforming. 5G New Radio (NR) made its long-awaited commercial debut in late 2018. Offering significantly faster speeds and greater capacity compared to 4G Long Term Evolution (LTE), 5G NR…

Choose a 5G base station’s PA bias control circuit

Ritesh Jain, Pratik Kalyanasundaram, and Himanshu Khatri, Renesas Electronics — Wed, 03 Apr 2024 09:48:19 +0000

Bias control of PAs is crucial to ensure optimum radio performance under all conditions. Current sensing and temperature sensing provide the feedback needed to control the PA bias. The choice of sensing and biasing circuits brings design trade-offs. 5G base station power amplifiers (PAs) need biasing using a separate bias controller to maintain optimum performance…

Build a 5G Open RAN test lab with open-source software tools

Lincoln Lavoie, University of New Hampshire Interoperability Lab — Wed, 20 Mar 2024 09:27:38 +0000

Open-source software provides network components that you can use to simulate 5G network functions from the network core to the radio. Developing and deploying a laboratory infrastructure to support testing 5G and open radio-access network (Open RAN) systems can present a daunting and complex task. Prior to Open RAN, this task was only possible by…
