Sažetak
Today, the Wi-Fi technology is practically used as a default connectivity solution for many new technologies and concepts like Internet of Things (IoT) and Smart City. The design of Wi-Fi network is a complex problem where it is necessary to decide about the location and number of access points in given indoor or outdoor environment. In this paper the measurement results of Wi-Fi signal in the indoor-to-outdoor building environment are investigated and possible sources of signal loss in the examined Wi-Fi channel are pointed out and discussed. The influence of human hand signal absorption is examined by comparison of the measurements performed by professional equipment with the ones obtained by a smart phone. We considered different receiver positions as well as the change of transmitter antenna gain with respect to the receiver height. The gain correction was estimated, and results showed a good agreement between the calculated and measured power levels at the receiver
