Abstract: Background and Objective: Today, Wi-Fi technology is practically being 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.
Method and Results: 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 smartphone. We considered different
receiver positions as well as the change of transmitter antenna gain with respect to the receiver height.
Conclusion: The gain correction was estimated, and results showed a good agreement between the calculated
and measured power levels at the receiver.
