We will move step by step: first the core vocabulary, then a realistic scenario, then the language patterns that hold it all together, and finally a short practice activity. Take your time, read the dialogue aloud, and try to reproduce the patterns in your own words.

Key vocabulary

Before the scenario, study these eight essential terms. Read each definition aloud, then write one sentence per term using a real situation from your own work in Telecommunications.

**latency** — delay in data transfer.

**throughput** — data rate over a link.

**churn** — customer loss rate.

**ARPU** — average revenue per user.

**interconnect** — links between operators.

**footprint** — geographic coverage.

**SLA** — service level agreement.

**backhaul** — connection between cells and core network.

Scenario in context

It is Monday morning. You are sitting in a meeting room with two international colleagues. The agenda mentions network reviews, and your manager has asked you to lead the discussion. You take a breath and begin.

"Thank you all for joining. Today I would like us to focus on network reviews, because it directly affects how we serve our clients in Telecommunications. I will start with a short summary, then I would like to hear your views before we agree on next steps."
