Can anyone help me?

I'm currently working on a project related to telecom software development, and I could really use some guidance. This is my first time working in this field, so I have a few questions: What are the key trends in telecom software development right now? Are there any specific programming languages or tools that are commonly used in telecom enterprise software development? Can someone recommend resources or online courses to get started in this field? I'd appreciate any insights or advice you can provide. Thanks in advance!
