IoT, the Internet of Things
The Internet of Things is a set of intelligent devices connected to 4G and 5G mobile networks that can collect and transmit data using peripherals with built-in sensors, and process evaluate and display large amounts of data with IT devices.
The technologies based on LTE networks are Cat-M and Cat-NB (NB-IoT), the differences between which are shown in the following table.

Structure of the ARTEMISZ system
The common features of terminal equipment (peripherals) are summarized as follows. They
- can be used locally anywhere
- can operate in the network in the hundreds of thousands or even millions
- have low power consumption (several years of battery life)
- are manageable
- are immediately operational
- have FOTA capability (Firmware upgrade Over The Air)
- can connect to the network even at very low field strength (<-110dBm)
Service-specific application servers process and evaluate signals from peripherals furthermore manage peripherals.
The presentation function displays data of the given functional operation on local user terminals or smartphones.
Development model
Motto: As many customers so many special needs, that have to be met in a short time, at an optimal cost level.
This is ensured by sensor and CPU modules developed and tested for peripherals on the one hand, and by the flexible and easily scalable design of the existing IT framework on the other hand.
Key features of the client-server solution:
The server-side software environment can be flexibly designed according to the user's needs. Both thin and thick client interfaces can be requested with the same functionality. System security meets the IT security requirements of current client-server solutions (encrypted communication, checking the integrity of stored data, storing data in a database, extensive user and system logs). The system has a multi-level hierarchical user and entity management module that allows to model the user's organizational structure and the flexibly mapping of sensor groups and individual user groups.
In the following, we present three specific applications.

In the following, we present three specific applications.
Object/area supervision
The task of the ARTEMISZ object / area monitoring subsystem is to process the signals of peripherals located in a given object or geographical area. Depending on the task, various sensors can be installed in the peripherals: such as motion detectors (infra, radar), sensors measuring meteorological parameters (temperature, humidity, wind speed, air quality, etc.), sensors for detecting radioactivity and gas concentration, magnetic parameters. A peripheral unit can be equipped with several sensors that perform different sensor functions.

On the left side of the screen, the upper window shows the indications of the selected endpoints in chronological order, the middle field shows the indications of all managed endpoints in chronological order, while the lower part shows the status information of the selected endpoints and the aggregate statistics. The desired map detail is shown on the right side of the screen (2D map, satellite or street view can be selected). The following maintenance management functions can be performed from the client interface to the terminals:
- switching equipment on / off
- sensor configuration, enable / disable
- configuration of sensor parameters, scheduling of switching on and off per part of the day
- other equipment configurations
- querying / displaying internal statistics
- remote firmware update (Firmware Over The Air, FOTA).
Object tracking
The task of the ARTEMISZ object tracking subsystem is to process and display the signals of moving transmitters in a given geographical area on a dynamic map interface. The primary function of the transmitters is to transmit the GPS information needed to track the object, but depending on the task, additional sensors can also be installed (heat sensor, gas sensor, sound sensor…, etc.).
Peripherals are connected to the LTE network (CAT-M 2G backup possible), signals are received on a central server connected to a closed APN network. The results can be evaluated on local user terminals or smartphones. The server is adequately protected and connected to the open Internet so that remote operators can query the appropriate data and operators with mobile devices can track the movement of objects.

Tracking accuracy is shown by object tracking in a roundabout on the right.
Tracking also displays altitude values.
Site surveillance
The task of the ARTEMISZ site surveillance subsystem is to process the signals of peripherals located in a given object or geographical area. The peripherals are basically equipped with a microphone and/ or a motion detector, but other sensors (light sensor, heat sensor, gas sensor etc.) can also be installed depending on the task. The peripherals are connected to the LTE network, and the signals are received on a central server connected to a closed APN network. The results can be evaluated on local user terminals or smartphones. The server is properly protected and connected to the open Internet so that remote operators can query the appropriate data (even on a mobile terminal).
