The importance of dB for RF design
In the face of a project indicator of RF design, one of the most common words is “dB”. For an RF engineer, dB is sometimes as familiar as its name. dB is a logarithmic unit that provides a convenient way to express ratios, such as the ratio between an input signal and an...Read more -
LoRa VS LoRaWan
LoRa is short for Long Range. It is a low-distance, distance-distance close-contact technology. It is a kind of method, whose biggest feature is the longer distance of wireless transmission in the same series (GF, FSK, etc.) spread farther, the problem of measuring dist...Read more -
