Telecom: how the sector works
how telecom works: building and running networks, the enormous fixed-cost model, spectrum and regulation, and the fight against becoming a dumb pipe.
Telecom is a capital-intensive, network-driven sector where infrastructure economics, spectrum policy, and regulation shape competitive outcomes as much as consumer demand. This block gives you the end-to-end map: how networks are built and monetized, who captures value across the chain from equipment vendors to carriers to content players, and why regulators remain central actors rather than background referees. You will learn the structural forces behind pricing, consolidation, and infrastructure investment, plus the numbers, acronyms, and benchmarks practitioners use daily to assess a market, a carrier, or a deal. The goal is fluency: reading a telecom business or transaction the way an operator, regulator, or investor would, quickly and with the right reference points.
What you'll master
- Map the telecom value chain from network infrastructure to end-user services and identify where margin concentrates
- Analyze competitive dynamics between incumbents, challengers, MVNOs, and equipment suppliers in a given market
- Identify which regulations and regulatory bodies govern a telecom decision (spectrum, pricing, interconnection, privacy) and what compliance they require
- Use core telecom metrics (ARPU, churn, EBITDA margin, capex intensity) to evaluate a carrier's performance or benchmark a market
