Does the PS3 give off wi-fi?

Hello, I have a strange question and not sure how to ask it but I currently have two ps3s at two different locations. One being my apartment and then one being my house and I have been noticing on my itouch and now I notice it on my computer, I can look for wireless networks and I always see a strong signal from my PS3 I assume. I'm at home and right now it says PS3-3719771, I use wi-fi at my house but at my apartment there are too many routers around so I just use ethernet but I get something very similar even with the PS3 plugged in. It says it's a secure connection, I'm wondering what would is this giving off and what could the password be. I'm hoping that maybe I can use that pocket-blu app with it at my apartment since I do not use wi-fi there, hopefully someone can let me in on the info. Thanks, Joe.
