Table 1 Use cases: traffic aspects and requirements
From: Optimisation of NB-IoT deployment for smart energy distribution networks
Use case | Traffic aspects (UL = Uplink/DL = Downlink) | Requirements |
|---|---|---|
Meter reading (scheduled) | 4–6 messages/residential meter/day; 1600–2400 bytes (UL) | ≤ 4 h, ≥ 98% |
12–24 messages/industrial meter/day; 200–1600 bytes (DL) | ≤ 2 h, ≥ 98% | |
RTP | 60/1000 meters: 1 message/day 100 bytes (DL) + 25 bytes (UL) | ≤ 5 s, ≥ 99% |
Service switch operation | 1–50/1000 meters: 1 message/day 25 bytes (DL) + 25 bytes (UL) | ≤ 1–2 min, ≥ 98% |
ORM | 1 message/meter/event 25 bytes (UL) | ≤ 20 s, ≥ 30%a |
Firmware updates | 2×/meter/year 400–2000 kB (DL) | ≤ 4 h, ≥ 98% |
