From the field
The same lessons come up again and again from people actually doing the job:
People think telecoms is fixing phone lines. I design mobile networks that serve hundreds of thousands of people and roll out 5G infrastructure. It's serious engineering, and the world quite literally can't function without it.

Data demand keeps doubling, which means the networks always need upgrading, expanding, optimising. I have never once worried about work — connectivity is the infrastructure everything else runs on.
Senior network engineer · 12 years in
I love the mix. One day I'm designing network architecture at a desk, the next I'm out commissioning fibre in the field. It's well paid, it's future-proof, and you can see the connected world you helped build.
