Using inbuilt and external WiFi simultaneously.

I am using a HP laptop, there is inbuilt WiFi device for it, and I have an additional USB WiFi device (external) for my desktop.The thing I want to know is, can I simultaneously utilize my USB WiFi device (external) and internal in order to get high data rate. Can both of these devices work in co-ordination with each other to provide fast Internet Experience? Any Suggestions?
