In this paper the basic assumptions of a Radio Signal Strength Indicator - based fingerprint and the influence of human body on the results are presented. The main focus is put on the influence of the obstruction of line-of-sight between access point and transceiver by a human body. This issue must be corrected in order to gain more accurate and reliable results of the positioning. The mathematical model for correction of this issue is proposed along with some examples. The examples are based on the real measurements made by authors. Presented correction formula allows to minimize the influence of the user - access point direction on the results obtained during fingerprint creation and positioning.
