SAR Assessment of Google Glasses at Cellular Wireless Frequency Bands

Ver documento

Detalhes bibliográficos
Resumo:The use of wearable devices, like smartwatches and smartglasses, with wireless communication capabilities are now becoming common. The use of such devices, radiating electromagnetic waves close to the human body, is also becoming a matter of concern. The SAR assessment of Google Glasses for 0.9 GHz, 1.94 GHz, 2.43 GHz and 2.6 GHz bands, corresponding to cellular (GSM, UMTS and LTE) and wireless (Wi-Fi), is presented. The assessment scenario is presented, and the simulations methodology is described. From simulations results, one concludes that the maximum recommended SAR value for the human head is only exceeded in the 0.9 GHz (GSM) band. For Wi-Fi, UMTS and LTE, there are no problems of exposure, since the maximum radiated power that fulfils SAR requirements is above the maximum power that a mobile terminal can radiate, according to the standards
