General information

How does the IoThon setup work?

The network (as shown in the diagram below) consists of a radio access network (i.e. radio head with antenna and radio base band unit) i.e NB-IoT Base Station (working on 700MHz or 1.8GHz) and packet core along with the user equipment to access the network.The user equipment may consist of a sensor (with an embedded sim) or an Arduino/Raspberry Pi connected to external sensors.

When the hardware is powered up, the radio modem in the device will read the information in the SIM like operator code (PLMN) and start scanning the different NB-IOT frequencies until it finds a radio signal that includes the information in the SIM card. Next, the device will read the security information from the SIM card and sends registration and authentication messages encrypted with the security information read from the SIM card to the Packet Core in the network.The Packet core will decrypt the information received in the messages from the device with the information stored in the Packet Core Database (i.e. HSS). If the information in the HSS matches with the information received from the SIM card the Packet Core will assign an IP address to the device and will provide connectivity.

Sensors are attached to the hardware devices which detect the changes in the surroundings and send periodic updates. These updates can be obtained by a web service request and the data can be used for transforming into valuable results. The data can be obtained in a virtual machine or to the laptop for transformation. The data can be used with cloud platforms like Mindsphere to make valuable transformations and provide interesting results.

For applications using AR/VR, due to low latency and high bandwidth requirements, we use a Pico Base Station (Working on 2.6GHz) instead of the NB-IoT Base station. In this case, the team can utilize their own packet core. Each base station resource can be split into multiple slices for different teams each using one slice of the base station and their own packet core. Teams can also use the whole base station for themselves if required.

Additional Information:

The mobile network has coverage to Open Innovation house, so that the developers can deploy their sensors at the venue. The application and services implemented by the developers, if successful, could be easily commercialised since the provided network is equivalent to existing infrastructure recently deployed by commercial mobile operators following 3GPP standards. The test network includes all mobile network components, from the frequency range to the base station technology, and also includes the necessary data security and a number of both open code core networks and network manufacturers' core networks. Participants have a unique opportunity to use both the frequency range and the mobile network.Block Diagram of 5G Network Setup
