What elective to choose?

I'm a senior undergrad and I'm enlisting courses now for second semester. There are two electives I'm eyeing right now: Fundamentals of Deep Learning: Intro to AI. OR Introduction to Cellular Networks.

I can't decide between the two. I'm only allowed to take one. The first course sounds interesting because deep learning is the way of the future. But I am also considering a career in telecommunications, so the second option is appropriate. But I've heard not so great news about telecoms engineering. Some say that the pay is low in that position.

For engineering students taking electrical, electronics or computer engineering, which elective will you take?
