6 Requirements for IoT devices in the context of disaster

6.1 General requirements concerning disaster

The following Recommendations deal with telecommunications concerning disaster:
– [ITU-T Y.1271] provides network requirements and capabilities for emergency
telecommunications (ET).
– [ITU-T Y.2205] specifies technical considerations that can optionally be applied within the
next generation network (NGN) to enable ET. In addition, this Recommendation also
outlines the underlying technical principles involved in supporting ET.

These Recommendations deal with requirements and technical aspects for emergency
telecommunications. Assuming that the IoT applications will use the NGN during a disaster as a
telecommunication infrastructure, these requirements are fully applicable to them.

According to [ITU-T Y.2205], it is recommended to use the common alerting protocol (CAP)
defined in [ITU-T X.1303] in order to provide information interaction between alerting systems.

6.2 Requirements for IoT devices
All manufactured IoT devices are required to pass testing procedures.

These procedures should include testing of IoT devices under conditions beyond the operating
range (e.g., temperature, pressure, radiation) in order to verify their safety for the environment and
for humans during disaster. IoT devices must not cause complications or occurrences of
emergencies of other types.
Test conditions should be selected based on the characteristics of possible emergencies in the area
of deployment.

The test results and potential hazards caused by devices outside the operating range are required to
be introduced in the technical characteristics of the devices.

New IoT devices are recommended to be developed with an extended range of operating
characteristics (e.g., operating temperature, humidity, pressure). The requirement for IoT devices to
extend the range of operating characteristics is essential for IoT applications which could
potentially fail, due to the uncertainty of the environment behaviour and its impact on the IoT
devices during disaster.
Dissemination of this practice is recommended on widely used IoT device types. The operation of
IoT devices providing measurements during disaster might provide a database of environmental
parameter measurements during disasters of different natures. Such measurements would help to
make important conclusions about the stages of disaster occurrence and allow for taking them into
account in the IoT device design phase.

7 Requirements for operation of IoT applications during disaster

This clause describes requirements for IoT applications concerning their operation during disaster.
In particular, clauses 7.1 to 7.3 describe requirements for each of the three identified operating
strategies for IoT applications related to disaster, and clause 7.4 describes switching between two or
more operation strategies during disaster.
To improve the efficiency of the infrastructure resources associated with the operation of IoT
applications, it is recommended that IoT applications implement one or more of the following
operation strategies related to disaster.
All strategies assume that the IoT applications do not continue normal operation during a disaster,
but instead perform only tasks aimed at rescuing people.
