Quiz W1-L2 Answer

Question 1)

Note: This quiz is a training exercise, which is not included in the final score.

W1.L2.Q1: A cellular network is made of

• a set of radio stations retransmitting the information from the source to the recipient through successive hops on a radio channel
• a set of satellites interconnected to each other
• a set of base stations deployed across a large territory and connected to a fixed network

Question 2)

W1.L2.Q2: In a zone that is densely populated (tick two boxes),

• cells are large to allow many persons to be covered
• cells are large to minimize the number of base stations to be installed and avoid health issues with residents
• cells are small to provide a high capacity in Mbit/s/km2
• cells are small to minimize the network cost
• cells are small to minimize transmit powers

Question 3)

W1.L2.Q3: In a mobile network, the territory is divided into cells to (tick two boxes)

• allow each base station to have a satellite link with the network,
• make sure a terminal is always in range of a base station,
• restrain the waves within a limited space,
• increase the capacity of the network.

Question 4)

W1.L2.Q4: The beacon channel is

• transmitted by the terminal and is used to trigger the base stations,
• transmitted by the base station and is used to deactivate the terminals,
• transmitted by the base station and is used by the terminal to get an indication of the level of coverage.

Question 5)

W1.L2.Q5: Consider a terminal that does not detect any beacon channel. It means that:

• the user can only make emergency calls,
• the user has not paid his/her bill,
• no cellular network covers the area where the user is located
• the terminal does not have enough battery to reach the base station

Quiz W1-L3 Answer

Question 1)

Note: This quiz is a training exercise, which is not included in the final score.

W1.L3.Q1: SGW means

• Servile Gigantic Work
• Standalone Grouped gateWay
• Serving GateWay

Question 2)

W1.L3.Q2: An SGW

• is a server that sends the parameters of the network to the terminal,
• is a gateway that allows the 4G network and the Internet to interconnect to each other,
• is a gateway that serves a geographical area and that forwards data packets sent to or from terminals,
• is a gateway that forwards data packets sent to or from terminals and controls these packets based on predetermined security rulesfilters.

Question 3)

W1.L3.Q3: A PGW

• is a server that sends the parameters of the network to the terminal,
• is a gateway that allows the 4G network and the Internet to interconnect to each other,
• is a gateway that serves a geographical area and that forwards data packets sent to or from terminals,
• is a gateway that forwards data packets sent to or from terminals and controls these packets based on predetermined security rulesfilters.

Question 4)

W1.L3.Q4: When I use a 4G network (in a standard architecture), all the data packets sent to and from my terminal

• always go through a SGW and a PGW,
• always go through a PGW but through a SGW only when I am not at home,
• always go through a SGW but through a PGW only if I have a professional subscription.

W1.L4.Q1: In a 4G context, HSS means

• Holistic Serving System
• Home Subscriber Server
• Her Splendor's Ship
• Homo sapiens sapiens

Question 2)

W1.L4.Q2: When someone turns on his 4G terminal and connects to a 4G network,

• the subscriber profile stored in the SIM card is transferred to the HSS,
• the subscriber profile is permanently stored in the MME and is locally activated,
• the subscriber profile permanently stored in the HSS is transferred to the MME.

Question 3)

W1.L4.Q3: The MME (Mobility Management Entity)

• controls a set of base stations on a regional or national scale,
• determines the location of each terminal with an accuracy of a few dozen meters,
• filters user data packets.
