Course content

1 section • 12 lectures • 37m total length

  • Cellular Domain1:45

    Understand telecommunication by examining the three domains—consumer electronics, IP, and cellular—covering end-user devices, fixed and wireless access, and standards from IEEE, IETF, and 3GPP across 2G to 5G.

  • Evolution to 5G4:59

    Trace the evolution from 1G analog to 5G new radio, highlighting 2G GSM and CDMA, 3G UMTS, 4G LTE, and 5G NR with OFDM and massive MIMO.

  • Cellular Architecture4:41

    Explore how cellular architecture links radio access and core networks, with sector antennas, backhaul, mobility, roaming, and the IP-based multimedia subsystem, enabling data and voice services across 4G and 5G.

  • Value Chain3:46

    Investigate the telecom value chain from subscribers to operators, and the four offerings: mobile, internet, telephony, and TV, driven by network providers, service enablers, and creators.

  • Spectrum1:56

    Understand spectrum as the frequency bands, auctioned by regulators, and how bands are divided into slots for multiple operators or leased to a single operator with uplink and downlink pairings.

  • Multiplexing Techniques1:02

    Discover how multiplexing techniques enable simultaneous communication for multiple users, covering TDMA, FDM, CDMA, and OFDM, with 5G networks relying on this technique.

  • Setting up the Network Infrastructure4:52

    Set up a telecom network by surveying sites, planning coverage with simulations, acquiring locations, building and integrating equipment, and optimizing prelaunch and operations to meet key performance indicators.

  • Network Performance1:16

    Monitor voice and data KPIs, accessibility, returnability, and mobility, achieving call setup success above 98% and handover success above 98%, with data downlink and uplink throughput tied to cellular technologies.

  • Customer Journey2:28

    Explore the customer journey from buy to pay, detailing prepaid and postpaid plans, SIM activation, service use, charging, billing, and top-ups in telecom networks.

  • Business Financials5:51

    Analyze telecom operator financials by examining revenue, OpEx, CapEx, EBITA, and net income, and explore churn, ARPU, minutes of usage, and B2C/B2B service versus equipment revenue.

  • Conclusion0:31

    Conclude your understanding of the telecom operator business and connect for questions, further assistance, or consultancy services. Provide feedback on the course and share ideas to improve it.

  • Bonus: Role of AI in Communications4:46

    Discover how AI transforms communications through generative use cases like report summarization, knowledge base creation, and synthetic data, plus AI infusion into products.

Requirements

  • No prior technical background or knowledge on Telecom needed

Description

Welcome to the course Understanding the Telecom Operator Business. Telecommunications is vast industry estimated to reach a market size of 3.4T USD by 2022. It comprises 3 main domains- consumer electronics, internet and cellular. In this course we shall focus on the cellular domain which includes all the Gs you hear, starting from 2G, 3G, 4G and the most popular one 5G. This is a very generic course where the complex technical and business concepts are simplified and presented for the audience.

Some of the interesting topics we cover are history of cellular technologies and evolution to 5G, how does an operator setup the network, customer journeys and how does it impact the back-end operations and key financial ratios that determine the health of an operator business.

You need not have any prior technical background or knowledge on telecommunications for this course. So, if you are a student, working professional or even an investor aspiring to broaden your knowledge, this course is highly recommended for you.

Latest session added on AI in Communications where we explore how artificial intelligence is transforming network optimization, predictive maintenance, and customer service. Discover how machine learning algorithms help operators reduce costs, predict network failures before they happen, and personalize the user experience to maximize overall subscriber satisfaction.
