Feedback of the first International Workshop on Low‐EMF radio‐link technologies and wireless networks management

The workshop on Low-EMF radio-link technologies and wireless network management that was organised in conjunction with the ISWCS 2014 (11th International Symposium on Wireless Communication Systems) took place in the end of August in Barcelona.

After a talk by ANFR (Emmanuelle Conil), five papers were presented to an audience of 15 people. Their main conclusions are summarized below:
• Preliminary measurements show that available cellular technologies, current traffic conditions and user context, including services used, are main points to be taken into account when designing low-EMF solutions; an assessment of the impact on communications standards of the proposed approach was also provided
• It was shown using a capacity-based deployment tool that power consumption and EMF exposure optimizations often conflict each other, and that a compromise between both is required
• A systematic methodology to assess the real exposure levels was proposed which leverages a large-scale deployment of low-complexity dosimeters exploiting an IoT testbed
• A solution was detailed that integrates small cells with directive antennas to reduce the required uplink power transmission at end users to limit the associated EMF exposure
• A tool was presented for the prediction of whole-body and localized SARs and absorbed doses for indoor wireless network deployments

This session also allowed an interesting discussion on low-EMF and its place within 5G, with Emmanuelle Conil (ANFR), Dino Flore (Qualcomm, 3GPP), Milos Tesanovic (Fujitsu Laboratory Europe, LEXNET), Ramon Aguero (University of Cantabria, LEXNET) and Milica Popovic (Telekom Srbija, LEXNET). The Exposure Index defined in LEXNET was discussed in the context of the EMF public concern. Its complementary role with green networks was also analysed.

This workshop will help LEXNET partners to improve their results and their activities in dissemination and standardisation during the third and last year of the project.
