Making Laptop a wifi hotspot

[spider]

Hey guys, I use a Dell Inspiron 1545 model with Vista O/S with a dedicated internet connection provided by Hathway. I want to use my laptop as a wireless hotpot so that 2-3 other wifi enabled laptops can access internet through it. How can I do that? How much area this wifi setup will work within?

Thanks guys for reading!!!
