Achieving the “Internet of Everything” is the ultimate goal of the entire IoT industry. According to IoT Analytic statistics, the number of active IoT terminals worldwide is expected to grow to 27 billion by 2025, but there is still a significant gap from the industry-expectation of a trillion-level market. With the deep expansion of IoT … Read more
LoRa is a wireless network standard based on linear modulation. Linear Modulation: Linear modulation represents “compressed high-intensity radar pulses,” which is a signal whose frequency increases or decreases over time. It is commonly used in sonar and radar, and is also prevalent in spread spectrum technology. Linear Frequency Modulation Spread Spectrum: Linear frequency modulation spread … Read more
Have you ever noticed what your phone calls the wireless network in its settings? Some say that iPhones call it Wi-Fi, while Android phones refer to it as WLAN. In fact, regardless of whether you’re using an iPhone or an Android phone, or even the same model, there are instances where some call it Wi-Fi … Read more
Semi-conductor materials can be divided into two categories: elemental semiconductors and compound semiconductors. The former includes semiconductors formed from elements such as silicon (Si) and germanium (Ge), while the latter includes compounds such as gallium arsenide (GaAs), gallium nitride (GaN), and silicon carbide (SiC). In the past, semiconductors have undergone three generations of changes, gallium … Read more
