Best Readings in Communications in Wireless Networked Control
Wireless networked control has attracted a lot of attention from both academia and industry in the past two decades, and has become a hot topic in recent years, mainly driven by mission-critical Industrial Internet of Things (IIoT) applications requiring closed-loop control, such as intelligent transportation, Tele-surgery, industry automation, power systems automation, and power electronics control. Specifically, a wireless networked control system (WNCS) is a spatially distributed control system consisting of networked sensors, actuators and a controller. The wireless sensors measure and report the physical process states of interest, the remote controller collects the sensors’ measurements and generates control signals, and the wireless actuators receive the control signals and control the processes. Due to its spatially distributed nature, reliable, dynamic and secure wireless communications among sensor, contro
The Xiaomi Mi 11 series can be a bit confusing for those looking to get one of the many devices available. There are four Mi 11 smartphones plus a recent release known as the Mi 10T Pro. But in this article, we’ll be showing a quick specs comparison between two that have a similar price, the Mi 11i and the Mi 11 Lite. Here are the official specs, from the Mi website, for both of these devices:

Power Detector (100MHz to 70GHz): LTC5597
The LTC5597 from Analog Devices is a Linear-in-dB RMS power detector with a 35dB dynamic range. The LTC5597 is a high accuracy RMS power detector that provides a very wide RF input bandwidth, from 100MHz up to 70GHz. This makes the device suitable for a wide range of RF and microwave applications, such as point-to-point microwave links, instrumentation and power control applications.
The DC output voltage of the detector is an accurate representation of the average signal power applied to the RF input. The response is linear-in-dB with 28.5mV/dB logarithmic slope over a 35dB dynamic range with typically better than ±1dB accuracy. The detector is particularly suited for measurement of waveforms with crest factor (CF) as high as 12dB, and waveforms that exhibit a significant variation of the crest factor during measurement. Applications include Point-to-Point Microwave Links, SATCOM, Instrumentation and Measurement Equipment, Military Rad
