Thanks for respond. If we test with one device, when we going live, move concurrent user access to same AP, will the signal getting more low?

That's normal.

Different phones have different radios with different electronics such as demodulators and antennas and antenna placements. There's also the issue of not calibrating NICs so you might see different levels with the same type of phones.

You can't fix that, but you can take that into consideration when designig a WLAN network.
