Why open RAN needs testing to ensure interoperability
In a video interview, James Kimery of Spirent Communications explains how test plays the role of arbiter of communications among radio units, distribution units, and centralized units.
What’s inside Rakuten Mobile’s Open RAN radio?
5G Technology World spoke with Analog Devices’ Nitin Sharma on the massive MIMO technology deployed in 5G base stations from NEC.
LTE Cat 1 chip platform handles VoLTE/100 kbps IoT apps
Sequans Communications S.A. announced that its second-generation LTE Cat 1 chip platform, Calliope 2, will soon be sampling. Calliope 2 is designed for the cost-effective support of IoT applications that require VoLTE and a data rate higher than 100 kilobits per second that cannot be supported by LTE-M or NB-IoT technologies. Typical Calliope 2 applications […]

Power system design considerations for wireless IoT nodes and wearables – Virtual Roundtable (part 2)
The second part of EEWorld’s two-part “virtual roundtable” discussion on power system design considerations for wireless IoT nodes and wearables focuses on the use of switching regulators and the associated technical challenges. Our panelists are: Florian Feckl (FF), Systems Engineer and Product Definer for Low Power Buck Converter, Texas Instruments, and Kyle Van Renterghem, (KVR) […]
Power system design considerations for wireless IoT nodes and wearables – Virtual Roundtable (part 1)
The first part of EEWorld’s two-part “virtual roundtable” discussion on power system design considerations for wireless IoT nodes and wearables focuses on the use of low dropout regulators (LDOs). Our panelists are Kyle Van Renterghem, (KVR) Marketing & Applications Manager, Low Input Voltage LDOs, Texas Instruments, and Julian Hagedorn (JH), Systems Engineer, Texas Instruments. JS: […]
Designer’s guide to smart home tech, Part 2
This continues the discussion on smart home technology basics. You can find part 1 here. What is Z-Wave? Behind the Z-Wave standard is the Z-Wave Alliance. It is a wireless protocol that will connect and control smart home and IoT devices today. Today, there are over 3400 certified Z-Wave smart home devices on the market. […]
Envelope tracking improves power amplifier efficiency
RF power amplifiers consume lots of energy, which is a concern associated with 5G. Envelope tracking helps reduce power consumption but has tradeoffs.
mmWave antennas and antenna management for 5G
Antennas, antennas, and more antennas are one of the keys to successfully developing 5G new radio (NR) devices employing millimeter wave (mmWave) bandwidths. 5G NR handsets are highly complex devices. They have to handle the new 5G mmWave bands, including 4×4 multiple input and multiple output (MIMO) antennas, 3GPP specified Evolved Universal Terrestrial Radio Access […]
