Section Intro2:08
Introduction to Long Range (LoRa) Technology3:53
Explore the basics of LoRa technology within the IoT landscape, compare wireless options like Bluetooth, Wi-Fi, Zigbee, and cellular, and examine trade-offs between range and data rate.
Preparing to Build LoRa-Based Communication Systems
Link-Budget2:06
Explore how link budget measures the total cost of transmitting a signal between two points, considering geography, environment, obstacles, and gains. LoRa enables long-range, low-power IoT by minimizing data payloads.
Spread-Spectrum Modulation4:43
Mastering LoRa's spread spectrum takes chirp modulation to enable long-range, low-power IoT communication, reducing interference and enhancing security by making signals harder to detect.
Quiz
Chirp Modulation3:39
Chirp modulation encodes digital bits into unique chirps sent sequentially atop a carrier wave, forming LoRa's long-range communication method.
LoRa Frame2:44
Explore the LoRa frame structure, including preamble, syncword, and data, where chirp patterns encode symbols and reveal the message amid noise.
LoRa Factors - Bandwidth2:15
Explore how bandwidth, spreading factor, and coding rate shape LoRa transmission. Bandwidth measures signal change rate and throughput like a highway, while regulatory and hardware limits constrain options.
Quiz
LoRa Factors - Spreading Factor3:09
The spreading factor determines how data is spread over bandwidth, affecting range and data rate: higher factors extend range but slow transmission; lower factors boost data rate but shorten range.
LoRa Factors - Coding Rate4:14
Explore coding rate in LoRa, shown as x over y, and how it trades data throughput for error correction to balance range, reliability, and speed with spreading factor.
Who this course is for?5:23
Learn practical, step-by-step microcontroller and programming techniques for long-range connectivity with LoRa, taught by the Educational Engineering Team, trusted by over 250,000 students worldwide.
