How to compare the radio characteristics of embedded Wi-Fi modules?

Question

Iron

Hi guys, there is such a question, there are two embedded Wi-Fi modules, I finished programming, now I need to write a report and compare their radio characteristics, I found in the datasheets Transmitter output power (transmitter power) value for the first module +15 and for the second + 14 dBm and receiver sensitivity (receiver sensitivity) for the first module -87 and -88 dBm for the second. I need to choose which of the modules is better and why, and output the theoretical communication range. These modules will work as access points.
by the fact that I have already found this is the formula for calculating the total path gain,
Pt is the transmitter power, Gt is the transmit antenna gain, Gr is the receive antenna gain, Pmin is the real receiver sensitivity.
The higher the result, the better, if we assume that the transmitter is the same for both modules and the antennas are also the same, then substituting what we have, we get that they are almost almost the same in terms of characteristics. Tell me which way to dig. Thanks in advance

Answer 1

we find that they are almost almost identical in characteristics.

Actually the way it is. But the second one is not significantly worse - it has less transmitter power. Although the minimum sensitivity is higher. The difference between -87 and -88 dBm is significantly smaller (about 1.2 times, besides, there are numbers of the order of nanowatts ... so the difference of 1.2 no longer plays a role. ) than between 15 and 14 dBm (about two times )
