Gaming Wireless Keyboard

Can I upgrade to a better wireless mouse without having to get a new receiver?
I have a dell wireless keyboard and mouse that came with my new computer. I want to get a better wireless mouse (for gaming), but I do not know if the receiver for my current setup will accept a different mouse. Will it? Is the technology bluetooth-like? Does one work for all? Thanks in advance
if you buy a new wireless mouse then it will come with a reciever anyway. so your question is pretty much invalid anyway.
