Solutions based on devices operating with limited resources and wireless data transfer technologies can form autonomous sensor networks that enable monitoring of the operating environment and local data processing. These devices, such as sensor nodes and IoT devices, have the ability to communicate with each other and interact with services via the Internet. Based on data collected from the physical world, the system's devices, either independently or with cloud support, process data and operate in their environment.
The unit's expertise is based on several years of experience in corporate collaboration with embedded systems and wireless technologies, and it has its own development platform for implementing IoT applications.

ICT Unit has developed many different wireless platforms for sensor network applications with following hardware: Atmega128L+CC2420 board, Jennic JN5139 modules, Zigbit 2.4GHz and 868Mhz modules. We have named our platform as CiNetNode.
CiNetNodeV1 (2004)
Atmega128L+ Chipcon CC2420
CiNetNodeV2 (2009)
Jennic JN5139 (integrated 2.4GHz radio)
CiNetNodeV3 (2013)
Both 2.4GHz and 868MHz versions
CiNetNodeV4 (2015)
CiNetNodeV5
Currently used wireless IoT platform is our own design and it is based on Atmel's ATxmega256 microcontroller and IEEE802.15.4-compliant radio transceiver (AT86RF215M).
