From Signal to Service —
Telecom Network Design
Trace the invisible journey of every call, text, and data packet. Master signal physics, network architecture, access technologies, RF planning, and regulatory permitting — building the foundation to design telecom networks that connect billions.
Get StartedFrom Signal to Service
Every call, text, and data packet travels a journey you've never seen — until now. Discover the invisible infrastructure connecting 8 billion people.
Telecom Network Design is the discipline of planning, engineering, and deploying the physical and logical infrastructure that carries voice, data, and video across the globe — from cell towers to fiber optic cables to satellite links.

Module 1: The Telecom Universe
Module 2: Signal Fundamentals
Module Overview
Understand the physics behind every connection. From electromagnetic spectrum to link budgets, learn what makes signals travel — and fail.
Key Topics Covered
- Electromagnetic Spectrum
- Frequency, Wavelength & Bandwidth
- Modulation Techniques
- Signal Propagation & Loss
- Antennas & Link Budgets
Module Overview
Every network begins with a signal. This module takes you inside the physics — electromagnetic spectrum, the frequency-wavelength-bandwidth trio, how data is encoded onto radio waves through modulation, and why signals weaken, reflect, and scatter as they travel. You'll calculate link budgets and learn to predict whether a connection will work before a single tower is built.
- EM Spectrum Explore sub-1 GHz, mid-band, and mmWave — range vs. bandwidth trade-offs
- The Big Three Relate frequency, wavelength, and bandwidth using Shannon's theorem
- Modulation From AM/FM to 256-QAM — how bits ride on radio waves
- Propagation Path loss, reflection, diffraction, scattering, absorption, and multipath
- Antennas Omnidirectional, directional, parabolic — gain patterns and MIMO
- Link Budgets Calculate transmit power + gain − loss = does this link work?
- Capstone Signal Survival Challenge — design a path through real-world obstacles
Why does a 28 GHz (mmWave) signal lose coverage faster than a 700 MHz signal?
Module 3: Network Architecture Basics
Module Overview
Build a telecom network layer by layer — access, transport, core. Learn IP networking, topologies, and redundancy design.
Key Topics Covered
- Three-Layer Network Model
- RAN Architecture (Traditional, C-RAN, O-RAN)
- Transport — Fiber, Microwave, Satellite
- Core Network (4G EPC / 5G 5GC)
- Topologies & Redundancy
Module Overview
A network isn't just towers — it's a symphony of switches, routers, fiber, and software. This module builds the complete picture layer by layer: Radio Access Network (RAN) at the edge, transport in the middle, and the core network brain at the center. You'll learn IP networking for telecom, compare star/ring/mesh topologies, and design redundancy for 99.999% uptime.
- Three Layers Access, Transport, and Core — what each does and how they connect
- RAN Deep Dive Traditional, C-RAN, and O-RAN architectures — components and trade-offs
- Transport Fiber vs. microwave vs. satellite — when to use each
- Core Network 4G EPC and 5G 5GC — control plane vs. user plane, network slicing
- IP Essentials Addressing, subnetting, routing, VLANs, and QoS for telecom
- Topologies Star, ring, mesh — build each and simulate failures
- Redundancy Equipment, path, and power redundancy for five-nines uptime
- Capstone Assemble a complete end-to-end network for a township

Module 4: Access Network Technologies
Module Overview
Master the last mile — the most expensive and critical part of any network. From cellular planning to satellite communications.
Key Topics Covered
- Cell Coverage & Frequency Reuse
- Fiber to the X (FTTx)
- Small Cells & HetNets
- Wi-Fi in Telecom
- Satellite (GEO, MEO, LEO)
- Site Surveys & Acquisition
Module Overview
The most expensive, complex, and critical part of any network is the connection to the user. This module covers every last-mile technology — cellular planning with sectorization and frequency reuse, FTTx fiber variants, small cells and heterogeneous networks, Wi-Fi offloading, satellite constellations (GEO to LEO), and the physical process of site surveys and acquisition.
- Cellular Planning Cell coverage, sectorization, frequency reuse, and handover
- FTTx FTTH, FTTC, FTTN — fiber variants and their cost-performance trade-offs
- Small Cells Macro, micro, pico, femto — densification with HetNets and DAS
- Wi-Fi Wi-Fi 4 through 7, offloading, Passpoint, and Wi-Fi vs. 5G
- Satellite GEO, MEO, LEO orbits — Starlink, VSAT, and direct-to-device
- Site Surveys Search rings, candidate ID, RF surveys, structural analysis, leases
- Capstone Select the right last-mile technology for 5 real-world scenarios

Module 5: Introduction to Network Design
Module Overview
Turn engineering into economics. Learn the end-to-end design process from coverage and capacity planning to BOMs and RF tools.
Key Topics Covered
- Network Design Lifecycle
- Coverage & Capacity Planning
- Network Drawings & Symbols
- BOM & Cost Estimation
- Environmental & Structural Factors
- RF Planning Tools
Module Overview
Network design is where engineering meets economics — every decision is a trade-off. This module walks through the complete lifecycle: gathering requirements, predicting coverage with propagation models, estimating capacity from traffic models, reading and creating network drawings, building BOMs with cost estimation, accounting for wind, seismic, and temperature, and using RF planning tools like Atoll and Planet.
- Design Process 7 phases — requirements to optimization, and what happens if you skip one
- Coverage Planning Propagation models, clutter types, and coverage prediction heatmaps
- Capacity Planning Traffic models, busy hour, Erlang, growth projections
- Drawings Site layouts, cable routing, single-line diagrams, and standard symbols

Module 6: Regulatory, Permits & Site Basics
Module Overview
You can design the perfect network, but without permits it stays on paper. Navigate zoning, environmental compliance, and international permitting.
Key Topics Covered
- Regulatory Landscape (FCC, TRAI, Ofcom)
- Zoning & Tower Siting
- Environmental & Historical Compliance
- Permit Application Process
- International Permitting (US, India, UK)
Module Overview
You can design the perfect network, but if you can't get permits, it stays on paper. This module maps the regulatory landscape — federal spectrum authorities, local zoning boards, environmental reviews, aviation clearances, and EMF compliance. You'll walk through the permit application process step by step, compare permitting across US, India, and UK, and guide a cell site through a complete regulatory maze in the capstone.
