How LoRa Signals Are Generated

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

The Origin of Wi-Fi Technology

In the late 19th century, humanity invented the wireless telegraph, thus beginning the exploration of the wireless world. The wireless telegraph machines of the time used a spark-gap transmitter, primarily to transmit Morse code. Early wireless telegraph machines, with the Morse code design in the lower left corner This telegraph machine could not receive and … Read more

Understanding LoRa: Long Range, High SNR, and Low Error Rate

When we talk about “LoRa”, we are not referring to the beautiful “Lara” from Tomb Raider… LoRaWAN is a low-power wide-area network specification launched by the LoRa Alliance. This technology can provide a regional, national, or global network for battery-powered wireless devices. LoRaWAN targets some core needs in the Internet of Things (IoT), such as … Read more
