Prerequisite/Previous Knowledge

Pupils have basic knowledge of mobile phones and their general functions.

Lesson Content/Board Summary

National and International Carriers

What are GSM Carriers?

GSM carriers, also known as mobile network operators (MNOs) or service providers, are companies that own and operate the infrastructure (like cell towers and switches) required to provide mobile phone services to their subscribers. They enable users to make calls, send messages, and access the internet.

National GSM Carriers

National GSM carriers are telecommunication companies that operate within the borders of a single country. They provide mobile services primarily to subscribers within that specific nation.

The following are examples of national GSM carriers in Nigeria:

MTN Nigeria
Globacom (Glo)
Airtel Nigeria
9mobile (formerly Etisalat Nigeria)

International GSM Carriers

International GSM carriers are large telecommunication companies that operate across multiple countries, often having a presence in various regions or continents. They facilitate global communication and often have roaming agreements with other networks worldwide.

The following are examples of international GSM carriers:

Vodafone (UK, Germany, India, etc.)
AT&T (USA)
T-Mobile (USA, Europe)
Orange S.A. (France, Spain, Africa, etc.)
China Mobile (China)

Differences Between National and International Carriers

The following are key differences between national and international carriers:

Scope of Operation: National carriers operate within one country, while international carriers operate in multiple countries.
Customer Base: National carriers primarily serve customers within their home country, whereas international carriers serve a global customer base.
Roaming Services: National carriers often rely on agreements with other national or international carriers to provide roaming services when their subscribers travel abroad. International carriers often have their own networks in various countries, making roaming within their own group of networks easier.
Market Size: International carriers generally have a larger market share and presence globally compared to individual national carriers.

Teaching Methods/Instructional Techniques

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and asks them to name the network provider they use on their phones. The teacher then writes “National and International Carriers” on the board.
Pupils’ Activity: Pupils respond by naming their network providers (e.g., MTN, Glo, Airtel).
Learning Point: Pupils recall their network providers and are introduced to the lesson topic.

Step 2: Explanation of GSM Carriers

Time: 7 minutes
Teaching Skill: Explanation/Definition
Teacher’s Activity: The teacher defines what GSM carriers are, explaining their role in providing mobile services. The teacher uses the smartphone and SIM card display to illustrate.
Pupils’ Activity: Pupils listen attentively and ask questions for clarification.
Learning Point: Pupils understand the meaning and function of GSM carriers.

Step 3: National GSM Carriers

Time: 7 minutes
Teaching Skill: Listing/Identification
Teacher’s Activity: The teacher explains the concept of national carriers and lists examples of national GSM carriers in Nigeria, using the carrier map chart to show their coverage.
Pupils’ Activity: Pupils listen, take notes, and identify the national carriers mentioned.
Learning Point: Pupils can list and recognise national GSM carriers.

Step 4: International GSM Carriers

Time: 7 minutes
Teaching Skill: Listing/Identification
Teacher’s Activity: The teacher explains what international carriers are and provides examples of major international GSM carriers, pointing out their global presence on the map chart.
Pupils’ Activity: Pupils listen, take notes, and identify international carriers.
Learning Point: Pupils can list and recognise international GSM carriers.

Step 5: Differentiating Carriers

Time: 5 minutes
Teaching Skill: Comparison/Analysis
Teacher’s Activity: The teacher facilitates a discussion on the differences between national and international carriers, highlighting their scope of operation and services.
Pupils’ Activity: Pupils contribute to the discussion by stating observed differences.
Learning Point: Pupils can differentiate between national and international GSM carriers.

Step 6: Class Activity/Discussion

Time: 5 minutes
Teaching Skill: Application/Engagement
Teacher’s Activity: The teacher asks pupils to discuss how understanding different carriers can be useful in GSM maintenance and repairs, especially when dealing with unlocked phones or international travel.
Pupils’ Activity: Pupils share their thoughts and ideas on the practical application of the knowledge.
Learning Point: Pupils connect the lesson to practical scenarios in GSM maintenance.

Step 7: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Define a GSM carrier.
Mention three national GSM carriers in Nigeria.
List three international GSM carriers.
State two differences between national and international carriers.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 8: Conclusion

Time: 4 minutes
Teaching Skill: Summarisation/Consolidation
Teacher’s Activity: The teacher summarises the key points of the lesson, reiterating the importance of knowing different carriers. The teacher then assigns homework: “Research and write down two other international GSM carriers not mentioned in class, along with the countries they operate in.”
Pupils’ Activity: Pupils listen to the summary and copy the homework.
Learning Point: Pupils consolidate their learning and are given an assignment to reinforce knowledge.

Lesson Keywords

GSM Carrier – A company that provides mobile phone services.
National Carrier – A mobile network operating within a single country.
International Carrier – A mobile network operating in multiple countries.
Roaming – The ability to use your phone network services when outside your home network’s coverage area.

Differentiation

The lesson will cater to diverse learning styles through a combination of lecture, visual aids (chart, smartphone), and interactive discussions. The teacher will provide additional support to struggling pupils by simplifying explanations and offering more examples, while advanced pupils will be encouraged to lead discussions and research further.

Note for teachers using this lesson plan

Teachers should ensure they have current information on national and international carriers, as the telecommunications industry is dynamic. Encourage pupils to bring their own mobile phones (with permission) to identify their network providers. Emphasise the practical relevance of this knowledge for future GSM technicians.
