4G & LTE Architecture Presentation Quiz

Which gateway in the architecture is responsible for connecting to the Internet?

• Serving Gateway

• Packet Data Network Gateway (PDN Gateway)

• Home Subscriber Service

• Base Station

What information does Subscription Information in the Home Subscriber Server provide?

• Security codes to verify user identity

• Details about user's services and payments

• Unique identifier for the user

• Tracks user's location via eNodeB connections

What is eliminated in LTE to achieve less processing compared to 3G?

• RNC (Radio Network Controller)

• Base station

• S-GW (Serving Gateway)

• HSS (Home Subscriber Server)

What is the main advantage of Multiple-Input Multiple-Output (MIMO) technology in radio communications?

• It uses a single antenna for higher power

• It allows multiple antennas to transmit multiple data streams

• It reduces the number of data streams

• It eliminates the need for antennas

Explain how the elimination of RNC in LTE contributes to lower latency compared to 3G networks.

• It reduces the number of processing steps, allowing data to travel faster through the network.

• It increases the number of network nodes, causing more delays.

• It requires more complex routing, slowing down data transmission.

• It introduces additional encryption, increasing latency.

What is the main function of the P-GW in the data path?

• Decapsulates and sends data to your phone

• Assigns and anchors your IP address

• Initiates the data stream

• Forwards packets to the serving eNodeB

Which of the following is not a core function of MME

• Session Management

• Paging and Tracking

• Wireless Connection

• Authentication

Explain the role of eNodeB in the final stage of the Spotify streaming data path and discuss its importance for wireless delivery.

• eNodeB initiates the data stream

• eNodeB forwards packets to the S-GW

• eNodeB decapsulates and sends data over air interface to your phone

• eNodeB assigns and anchors your IP address
