IoT platform

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).
