The final test

E1 What is an Ambient IoT device, in the published architecture specification's own words?

• An IoT device powered by energy harvesting, with limited energy storage capability
• A device that only works inside a factory
• A low-cost device with a ten-year battery

E2 In this release, what does the architecture specification say the Ambient IoT system is?

• A feature of every public 5G network
• A roaming agreement between operators
• An isolated private network that does not interact with a public network

E3 Which single work item carries more documents than any other in the area?

• The RAN solutions study, with 2357
• The SA3 security study, with 726
• The SA2 architecture normative work, with 695

E4 Four work items share the short name AmbientIoT-CT and each shows 959 documents. What is the correct reading?

• Each group filed 959 of its own
• The four counts add together to give the CT total
• It is one set of 959 documents counted four times, and the numbers must never be added

E5 How many groups have actually filed an Ambient IoT document?

• 37
• 16
• 17

E6 Which specification carries the most Ambient IoT change requests?

• TS 23.369, with 524
• TS 33.369, with 150
• TS 24.369, with 144

E7 A work item's completion percentage tells you what?

• How much of the work is done today
• How far along a target was judged to be when the row was last edited
• Whether the work succeeded

E8 Which group sent 139 of the area's 351 letters to other groups?

• SA2, the architecture group
• RAN1, the physical layer group
• CT4, the core network protocol group

E9 Which document opened the whole area, and at which plenary?

• RP-232404 at RP-101
• SP-250377 at SP-107
• SP-220085 at SP-95-e

E10 Which of these can this course not tell you?

• Which group owns TS 38.391
• Why a group decided something
• How many documents were filed in 2025

E11 What does 3GPP's founding study say powers an Ambient IoT device?

• A very small rechargeable battery
• Energy harvesting, with either no battery or a capacitor
• A power cable shared with the sensor it sits on

E12 What does a work item short name starting `FS_` tell you?

• It is a frozen specification
• It is a fast-track item
• It is a feasibility study, which writes a report and no binding text

E13 How many groups have actually filed an Ambient IoT document?

• 17
• 37
• 16

E14 Which single item carries more documents than any other in this area?

E15 Which group owns the new Ambient IoT medium access control protocol?

• RAN3
• RAN1
• RAN2

E16 What is TS 22.369?

• The architecture of the Ambient IoT system
• The service requirements for Ambient power-enabled IoT
• The signalling a device exchanges with the network

E17 Which specification did SA2's Ambient IoT work create from nothing?

• TS 23.369
• TS 23.502
• TS 23.501

E18 What does SA3's study say it set out to identify?

• Potential threats and security requirements for AIoT services
• The best encryption algorithm for tags
• How much power a signature costs

E19 How many separate work items share the short name `AmbientIoT-CT`?

• One
• Two
• Four, one each for CT1, CT3, CT4 and an umbrella row

E20 What are the three work items SA5 leads?

• Charging, management, and a phase 2 charging study
• Security, charging, and testing
• Architecture, management, and requirements
