Hi Sungjin,
Thank you for your question, unfortuantely it is impossible to answer!
All Wi-Fi networks are subject to outside influences from interference, signal reflection and refraction, attenuation from buildings, trees, people and a host of other factors, all of which will affect the performance of the network.
Additionally the deployment type (indoor/outdoor, open/cluttered) traffic type, quantity of and end-user/client device type will also have an effect on the performance of each individual connection as well as the network as a whole.
I would recommend looking at wireless network education courses such as CWNA and CWDP to learn more about how wireless networks operate and how they are affected as I've described above.
