How to select Wireless Modules? (Re-published No. 219)



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?
