The final test

E1 In one sentence, what is an Ambient IoT device?

• A device powered by energy harvesting, with limited energy storage capability
• A device with a ten-year battery that is never replaced
• A device that draws power over a wired connection to a base station

E2 How many groups have filed Ambient IoT documents, and how many documents are there in total?

• 37 groups, 2357 documents
• 16 groups, 10771 documents
• 179 groups, 900 documents

E3 Which two groups filed the most Ambient IoT documents?

• CT1 and CT4
• RAN1 with 2421 and SA2 with 2125
• SA1 and SA5

E4 Which document opened the whole Ambient IoT area?

• RP-232404, the RAN feasibility study
• SP-220085, the founding SA1 study
• SP-250377, the architecture work item

E5 How many specifications are touched by this work, and how does one qualify?

• 15, the ones whose title names Ambient IoT
• 37, one per work item
• 53, if a work item description declares it impacted or at least ten Ambient IoT documents name it

E6 What does a completion percentage in this data actually record?

• The share of member companies that have approved it
• Measured progress against the finished text
• The completion field of that item's row in the 3GPP Work Plan, as fresh as its last edit

E7 Four work items each show 959 documents. What is the correct reading?

• They share one short name, and counts are per short name, so the same 959 are shown four times
• Their counts can be added together to give the CT total
• Each of the four ran a separate effort of that size

E8 What does this record say about why a group reached a decision?

• It carries the vote counts
• Nothing — it holds only the outcome word beside a document number
• It carries a short summary of the debate for each document

E9 What powers an Ambient IoT device?

• Energy harvesting, with either no battery at all or a capacitor holding a little charge
• A battery that lasts ten years and is then replaced
• A very small rechargeable battery, topped up over the air

E10 What does the prefix `FS_` on a work item's short name tell you?

• That it is a fast-tracked item with a shortened approval
• That it is a final specification ready for implementation
• That it is a feasibility study, which investigates and writes a report

E11 Which two groups filed the most Ambient IoT documents?

• RAN2 and RAN3
• SA1 and SA2
• RAN1 and SA2

E12 Which single study carries more documents than any other item in this area?

• The SA3 security study
• The SA1 founding study
• The RAN solutions study, FS_Ambient_IoT_solutions

E13 How does a specification get into this register at all?

• Its owning group asks for it to be listed
• It contains the words "Ambient IoT" in its title
• A work item description declares it impacted, or at least ten Ambient IoT documents name it

E14 How many of the 37 work items stand at 100 per cent complete?

• 10
• All 37
• 19

E15 What is the right thing to type into a 3GPP document search to find this work?

• The name of the company that proposed it
• The work item's short name, such as AmbientIoT-ARC
• The phrase "battery-less device"
