Dell Wireless?

I just realized something. I ordered the new V130, and in the review on notebook check it says it uses the Intel 5100 for a wireless card. But when I check my specs from what I ordered it says "Dell Wireless 1702 802.11n/BT3.0 Networking Combo Card" now is that a card that is any good, and what the heck does BT3.0 mean?
