1. What is Demand?
In economics, demand refers to the quantity of a product or service consumers are willing and able to purchase over a period of time.
For broadband services, demand is affected by:
- Price
- Income level
- User preferences
- Population demographics
- Future expectations
- Availability of substitute services
Practical telecom example:
- Lower broadband prices generally increase subscriber adoption.
2. Why Demand Estimation Matters in Broadband Planning?
Demand estimation is one of the most critical parts of telecom business planning.
Incorrect estimation may lead to:
- Over investment in infrastructure
- Under dimensioned networks
- Poor ROI
- Low utilization of deployed assets
Example:
- Deploying high capacity fibre infrastructure in low demand regions can create financially unsustainable projects.
3. Major Challenges in Demand Forecasting
Long term telecom forecasting is difficult because demand changes rapidly due to:
- New technologies
- Economic recessions
- Political instability
- User behaviour changes
- Emerging applications
Practical observation:
- Many broadband forecasts fail because future service usage patterns are unpredictable.
4. Main Drivers of Telecom Demand
| Driver | Impact on Demand |
|---|---|
| Price | Lower prices increase adoption |
| GDP per capita | Higher income increases demand |
| PPP | Influences affordability |
| Teledensity | Indicates telecom maturity |
| Demographics | Impacts usage patterns |
Important data sources:
- ITU DataHub
- World Bank Open Data
- National regulator statistics
5. Common Demand Estimation Methods
Different methods are used depending on service maturity and market stability.
| Method | Typical Usage |
|---|---|
| Historical Data | Mature telecom markets |
| Econometric Models | Broadband forecasting |
| Surveys | New services |
| Experimental Tests | Product trials |
| Delphi Method | Long term forecasting |
6. Econometric Demand Estimation
Econometric models estimate broadband penetration using variables like:
- Price
- GDP per capita
- Broadband penetration history
- Technology adoption timing
Common OECD broadband demand model:
7. Understanding Elasticity in Broadband Demand
Price elasticity:
- A 1% decrease in price may increase demand by around 0.43%.
Income elasticity:
- A 1% increase in GDP per capita may increase demand by around 0.78%.
Practical learning:
- Broadband demand is highly linked to affordability and national economic growth.

8. Delphi Method for Long-Term Forecasting
The Delphi Method uses expert consensus for future forecasting.
Process:
- Experts answer questionnaires
- Responses are consolidated
- Divergences are analyzed
- Multiple rounds continue until consensus
Best used for:
- 5G demand forecasting
- New technology adoption
- Long range public policy planning
Practical advantage:
- Useful when historical data is unavailable.
9. Demand Estimation for 5G Services
5G demand estimation follows mobile demand principles but includes additional service layers.
Main 5G business segments:
- eMBB (Enhanced Mobile Broadband)
- FWA (Fixed Wireless Access)
- URLLC
- mMTC
Key practical observation:
- Early 5G adoption usually grows faster than previous generations due to digital ecosystem maturity.
10. Fixed Wireless Access (FWA) Perspective
5G FWA allows operators to provide broadband without deploying fibre to homes.
Advantages:
- Faster rollout
- Lower access network CAPEX
- Suitable for underserved areas
Practical deployment consideration:
- FWA demand estimation should align with fixed broadband market demand.
11. Demand Segmentation
After total demand estimation, markets are divided into segments.
Segmentation examples:
- Urban vs rural
- Consumer vs enterprise
- High income vs low income users
Important principle:
- Segments must be:
- Homogeneous enough for modelling
- Large enough for meaningful analysis
12. Estimating Market Share of New Entrants
Market share estimation depends on:
- Existing competition
- Regulatory policies
- Spectrum availability
- Infrastructure sharing rules
If competition increases over time:
- S curve models are commonly used for forecasting market evolution.
Practical telecom observation:
- MVNOs and RAN sharing can significantly impact future market dynamics.
13. Practical Learning from This Module
