Wireless Wide Area Networks (WWAN) Quiz

What does WWAN stand for?

• Wireless Wide Area Network

• Wireless Local Area Network

• Wired Wide Area Network

• Wired Local Area Network

What is the main difference between WWAN and WLAN?

• WWAN is more cost-effective than WLAN

• WWAN uses cellular network technologies, while WLAN uses WiFi

• WWAN is faster than WLAN

• WWAN has limited coverage compared to WLAN

What is the main advantage of WWAN?

• More convenient to use and fewer signal problems

• Limited coverage and high cost

• Less flexible with cloud management

• Slower deployment for new applications

What is the main disadvantage of WWAN?

• Increased throughput during large coverage area

• WWAN is not limited to mobile devices/networks only

• Replacement of lost WWAN may be costly

• Reliable network connectivity with no interruptions

What is the core idea behind the cellular network concept?

• Having a single frequency for the entire network

• Multiple lower-power base stations servicing mobile users within their coverage area

• Using only one base station to cover an entire city

• Using high-power base stations for better coverage

What is the frequency reuse factor?

• The number of cells in the network

• The distance between centers of adjacent cells

• The rate at which the same frequency can be used in the network

• The number of antennas in each cell

What is the purpose of clustering in cellular networks?

• To organize cells into clusters for frequency reuse

• To decrease the capacity of the network

• To reduce the coverage area of each cell

• To increase the interference in the network

What is the main advantage of using a hexagonal pattern for cell coverage?

• It increases the interference in the network

• It generates no holes and no cell superposition

• It allows for circular coverage areas

• It reduces the number of cells per cluster

What is the cluster size in the given cellular network system?

• 10

• 12

• 7

• 5

What is the maximum number of voice channels per cell in a system with a cluster size of 7?

• 84

• 70

• 56

• 42
