#219 9 Important Questions about Wireless Modules Answered (for Arduino Makers)

At the end of the two videos, you will understand everything necessary about frequency, modulation, bandwidth, power, propagation and a few other aspects to take the right decision for your project. And you will learn at least two new words: Time and frequency domain. Questions answered: - Which module should I use? What is the operating range? What is the throughput? What is the connection reliability? Can it communicate one- or two way? How much energy is needed for the transmission? Which module is better? What is legal? What about security issues?
