An effective method using duty cycles for assessment of exposure to mobile communication systems
An effective method for assessment of exposure to the electric field of the wireless signals from mobile communication systems is still lack, since the transmission of wireless signals is related to the traffic and the exposure level varies with the traffic load. In this paper we study the allocatio...

| description | An effective method for assessment of exposure to the electric field of the wireless signals from mobile communication systems is still lack, since the transmission of wireless signals is related to the traffic and the exposure level varies with the traffic load. In this paper we study the allocation mechanism of the traffic time slots in the mobile communication systems, and analyze the probability of the number of simultaneously occupied traffic time slots. Based on the queuing theory, the duty cycle of the wireless signal can be calculated by the traffic load. We establish the theoretical relationship between the exposure level and the traffic load. The exposure level in a certain period can be directly extrapolated by the calculated duty cycle, and the maximum electric field measured in the max-hold mode. By this method the maximum electric field only needs to be measured one time. Much effort on measurement can be avoided. |
