4.3 Characteristics of the use cases
2b247f429fc1a284ed3457befe0efafe
103 874-2
4.3.1 Physical location

103 874-2
4.3.2 Topology

Most of the use cases are at least partly confined to buildings causing strong fading conditions. M...
2b247f429fc1a284ed3457befe0efafe
103 874-2
4.3.3 Roles
Each device within a use case can have similar role in terms of producing measurement results or e.g. switching the lights on/off and routing data. However, one or some of the devices need to be connected to a gateway which has further connection (e.g. cellular, LAN) to deliver the measurement results to the monitoring...
2b247f429fc1a284ed3457befe0efafe
103 874-2
4.3.4 Power sources
Electricity meters, streetlights and emergency lights are typically mains powered devices. Emergency lights need to deal with electricity cut-down situations, so despite of the normal use of the mains power, they are equipped with batteries. A typical regulation requires 90 minutes operation with batteries.
2b247f429fc1a284ed3457befe0efafe
103 874-2
4.3.5 Traffic characteristics
This profile is agnostic on used application data formats. However, the applications may require support of up to 1 500 Bytes of length due to use of IPv6. The traffic is mostly uplink, while configuration and some control may require downlink messaging. Local routing between RDs is seen lighting use case. Examples of ...
2b247f429fc1a284ed3457befe0efafe
103 874-2
4.3.6 Security
