The sampling rate refers to the speed at which an Analog-to-Digital Converter (ADC) samples the analog input, or the speed at which a Digital-to-Analog Converter (DAC) outputs the analog signal. This rate is typically provided by the external clock rate to these converters. However, modern ADCs and DACs often have an internal Phase-Locked Loop (PLL) … Read more
Research on the Low Power Mechanism of LoRa Devices With the rapid development of Internet of Things (IoT) technology, Low Power Wide Area Network (LPWAN) technology has become one of the research hotspots in the field of wireless communication. LoRa technology, as one of the representatives of LPWAN technology, is widely used in smart cities, … Read more
In addition to smart home networking and office space scenarios, many IoT device connections will occur in remote environments. In these new environments, limitations in M2M transmission coverage will lead to accessibility issues and a need for power connections. To address this, widely adopted LPWA solutions—LoRaWAN and 3GPP (LTE Cat M1 and Cat NB1) open … Read more
