WiFi SSID
Hi,
If you have more than one access point in the building/house, what are the Pros and Cons of assigning each access point the same SSID vs different SSIDs?
If there is one SSID, how does my phone or laptop would know which one to connect? If I walk around from one corner of the building to another corner of the building, do they automatically switch to different access point device nearby?
If I give different SSID to each AP (for example, "Kitchen", "Basement", "Loft", "Master"), then users will have to make the switch to different SSID depending on which area they are in. It is inconvenient to switch every time. But a couple of advantages that I can think of: (1) When AP is down, you know which one is down because that SSID won't show up from the list of wireless network. (2) If you set up a Chromecast on your TV which requires SSID, you know which AP/SSID was used for each Chromecast device.
Having said that, what are the considerations of determining whether to use the same SSID or not when you have multiple APs?

naming all access point with same name can cause conflict on the network
that`s mean you mobile or lap will found networks like wifi wifi wifi wifi

@Norm,
"It will then stick with that particular signal until it can no longer use it, and then choose again from the available signals. This happens automatically" ---> Say there are 10 same APs with same SSIDs in the building. Do users have to establish the connection to each AP with password initially? What I am referring to is, if you have 10 different SSIDs, then you have to enter password to make the connection to each AP at least once.(Then all you have to do is select a particular AP/SSID depending on where you are down the road).

No, you can set them all up with the same SSID, same password, same method (WEP, WPA, and WPA2). Here are some guidelines on why to choose one over the other: http://www.howtogeek.com/167783/htg-explains-the-difference-between-wep-wpa-and-wpa2-wireless-encryption-and-why-it-matters/
A particular device will need to be connected to one of them the first time, but then it should be able to auto-negotiate with any of them, depending upon the device and the internal settings. Most devices using default settings should work fine after connecting to the first access point. They should also detect any of the access points next time they are in the vicinity, and connect automatically.

Thanks for all the comments and I appreciate it.
I can see Pros and Cons.
Having separate SSIDs, it comes with having to make the switch manually to take advantage of stronger signal coming from AP near by.
Having the same SSID is convenient, however, your device will stay connected to the same AP as long as it gets the signal even though you may be right next to another AP. So your device will depend on slower connection and you don't even know it (unless you check the signal strength and make the switch manually).
So it sounds like six or half a dozen to me.

You can also set it up and experiment with either configuration, and see which works best for you.
