EMI/EMC testing of wireless sensor networking node

For the deployment of Wireless Sensor Networks (WSN) in nuclear reactor environment to monitor and measure the plant parameters, the WSN nodes should be rugged, able to withstand high temperature, radiation and should be qualified in the environmental tests, Electromagnetic compatibility (EMC) and seismic tests as per the international standards. Hence Industrial grade wireless sensor networking nodes which meet the required specifications have been designed and developed. The nodes after successful development and functionality testing have been subjected to EMC tests at EMI/EMC Lab in Indira Gandhi Centre for Atomic Research (IGCAR). Subsequently they have been successfully qualified for EMC tests at SAMEER (Society for Applied Microwave Electronic Engineering and Research), chennai. This paper describes briefly about the design and development of nodes, measures taken for EMC qualification of nodes, qualification tests done and the test results.
