What is mioty telegram splitting LPWAN?
Mioty (pronounced “My IoT”) is the latest contender in the increasing-crowded field of low power wide area network (LPWAN) offerings. According to the mioty website: “With its best-in-class reliability and scalability, mioty is designed for massive industrial and commercial IoT deployments.” Quite a goal. But with founders including Texas Instruments, Fraunhofer Institute for Integrated Circuits […]

5G RF filters need more innovation
RF filters have always been an important part of mobile devices, but in the 5G era, they are the key to unlocking the promised high bandwidth that will drive many 5G use cases.
5G, B5G, 6G: A tale of two similar conferences
Two conferences, held at the same time, covered mostly the same topics.
Attenuation networks and their measurement
An attenuator is a four-terminal, two-port network that reduces the amplitude of a signal without distorting its waveform. Attenuators are used in electronic instrumentation to precondition a signal for measurement and display. For example, the commonly-used 10:1 oscilloscope probe attenuates the signal voltage upstream from the analog channel input by a factor of ten, letting […]
How does RISC-V fit into automotive systems?
RISC-V is being used in a surprising range of automotive systems ranging from ASIL-D safety rated controllers and security co-processors, artificial intelligence (AI) accelerators, controllers for advanced electric vehicle (EV) battery chargers based on gallium-nitride (GaN) power semiconductors, and even in high-voltage monolithic motor drive controllers for light EVs. The following is a sampling of […]

5G Technology World and EE World present our first 5G handbook, digital edition.
Simulate, test, and verify to solve 5G RF design problems
Performing these three steps can improve mmWave and beamforming performance.
The difference between LEDs and photovoltaic cells
LED’s and photovoltaic cells play increasingly prominent roles in our world. Both are semiconductor diodes. The LED or light-emitting diode emits light while the photovoltaic cell converts light to electricity. The LED is a diode that emits light only when forward-biased. Under a forward voltage bias, electrons cross from the n-region and recombine with the […]
