Sometimes the best way to learn is by start doing things without thinking much and let our intuition guide us navigate.
Introduction: We use the mobile phone to stay connected with our friends and family, but little do we care to understand how it works. As a young undergraduate student who was most taught electrical engineering using wires, I always wondered how are we communicating without wires. So I went ahead and did my masters in wireless communication, but still, I couldn't understand it well. So, a while back (!) I started doing Ph.D, to begin my exploration to find that hidden gem- the source of all knowledge and potentially save it in my brain and hide it from the rest of the world.
Today (10/2022), there are several wireless technologies that are embedded into our mobile phones, but I am only good at one thing, Cellular Networks. Hopefully, I make a good effort in helping you understand how it works and maybe encourage you to pursue (convince) your deeper interests in the cellular network.
