Define the term "handover" in a cellular network.

• A process of transferring an active call from one cell to another
• A method to reduce interference
• A method for encryption
• A process of assigning frequencies

Explain why cells in a cellular network are hexagonal in design.

• It ensures full coverage with minimal overlap.
• It minimizes dropped calls.
• It is easier to construct towers.
• It improves the speed of communication.

Describe the role of the Base Station Subsystem (BSS) in a cellular network.

• Facilitates communication between user equipment and the network
• Provides interconnection to external networks
• Manages handovers and roaming
• Controls subscriber authentication

Use a practical example to describe how cells are divided in urban and rural areas.

• Smaller cells in urban areas to accommodate higher traffic
• Larger cells in urban areas due to high population density
• Smaller cells in rural areas for enhanced coverage
• Larger cells in urban areas to minimize infrastructure costs

Distinguish between a macrocell and a femtocell.

• A macrocell provides wide coverage, while a femtocell is for small-scale indoor use.
• A macrocell covers a smaller area than a femtocell.
• A femtocell is used for outdoor coverage, while a macrocell is for indoor use.
• Both are identical in functionality but differ in name.

Evaluate the effectiveness of using small cells in densely populated areas.

• They enhance capacity and reduce latency.
• They cause network congestion.
• They increase the cost of the network.
• They eliminate the need for base stations.

Define the term used to describe the region covered by a cellular base station.

• Cell
• Cluster
• Frequency Band
• Antenna

Recall the primary function of a Mobile Switching Center (MSC) in a cellular network.

• Call routing
• Signal encryption
• Internet connectivity
• Power distribution

Classify the different types of cells based on their coverage area.

• Macro, Micro, Pico, Femto
• Base, Tower, Repeater
• Primary, Secondary, Tertiary
• Small, Medium, Large

Differentiate between the roles of a base station and the Mobile Switching Center (MSC).

• The base station handles radio communication, while the MSC routes calls
• Both are responsible for routing calls
• The MSC provides internet access, while the base station encrypts calls
• Both manage handover processes
