Someone who is learning might believe that to determine the corresponding coverage of an AP, then the most important or only parameter is the transmission power, to this, does the gain of the antenna provided in dbi (according to the datasheet) influence the coverage study?
The gain of an antenna is the ratio between the power entering an antenna and the power leaving it. This gain is commonly referred to in dBi's, and refers to the comparison of how much energy comes out of the antenna in question, compared to what would come out of an isotropic antenna. An isotropic antenna is one that has a perfect spherical radiation pattern and a unity linear gain. The higher the profit, the greater the operating range.
