Help

I’m an ECE/communication student and I want to build my career in the telecommunications field. However, I’m confused about what I should focus on more. Should I spend more time studying subjects like Fourier Transforms, Signals and Systems, and other communication-theory concepts, or should I prioritize networking and practical telecom technologies? I haven’t been able to find clear guidance on what I actually need to study for a career in telecommunications. Since I’m the first person in my family to reach this level of education, I don’t have anyone around me who can properly guide me about career paths and industry requirements. I would really appreciate some guidance on what I should learn, what I should prioritize, and where I should focus my efforts to build a career in telecommunications.
