Knowing 5ghz Capability Based on ROM

[yomen9]

Hi,
I really need to know an information about a phone that I can't currently have on hand!

I need to know if the Samsung Galaxy S Duos has a 5ghz capability and I was wondering if it's possible to know it by looking at it's ROM or some other way considering I don't have the phone with me!

Thank you so much for any answer!
