What is the strength (range) of the Wi-Fi signal on PC motherboards?

Question

Iron

Hello.
On modern motherboards, a built-in Wi-Fi module is regularly found.
I was a little confused by the presence of antennas in the kit.
Based on this, the question arose, how powerful (in range) is the signal of such modules without using additional complete antennas?
Is it equal to the Wi-Fi signal strength of a laptop or phone?
Unfortunately, I could not find information on the Internet.
Thanks

Answer 1

Well, first of all, there are antennas in laptop adapters. On yes, they are simply built into the cover of the laptop.
On built-in motherboards, divorced on the board, there are no antennas. And to catch without them is unlikely that it will be even at a distance of a meter.
Remote antennas in motherboards so that the system unit by default stands in the niche of the computer desk, where radio waves penetrate much worse, + the motherboard is located in the metal case of the system unit, which jams the signal even more. Therefore, they are equipped with remote antennas, and in principle, choosing an alternative antenna, you can change the power and range.

Answer 2

how are you looking for it? it all depends on the module that is installed, see the specification for the motherboard, see the name of the wifi adapter, google its specification and look at its radiated power and sensitivity. Power and range are not completely the same concepts in this case, having more power you can "hit" far but can't hear anything back because the sensitivity is not enough. Usually the sensitivity is standard up to -80dBm, but it can be raised just with the help of antennas, you can buy a large antenna separately and hear the whole area.

Approximately 50 meters, almost like in a laptop, and even in a smartphone.
