5G and Wireless Communication for Beginners - Understanding Frequency Modulation

The lecture introduces frequency modulation, explaining its necessity in wireless communication due to the low range of human voice frequencies. It discusses how antennas can transmit high frequencies over long distances, enabling wireless communication. The process of frequency modulation involves encoding low-frequency data onto a high-frequency carrier. The lecture details the modulation and demodulation processes in mobile communication, highlighting the role of mobile devices and antennas. It concludes with a question about how towers identify messages for specific users, to be explored in the next lecture.

What is the difference between modulated frequency and demodulated output voice?

Describe the step-by-step process of how a mobile phone communicates with a tower.

How does a tower identify which message is for which user in a network with many mobiles?
