This is truly the ultimate wireless card for speed, range and versatility. It has 500mW of output power in BOTH frequency bands complemented by an excellent receive sensitivity, so you will be able to pick up weak signals from far away. You can use the extremely common 2.4Ghz frequency wherever you are, or in networks that use the 5Ghz frequency you can hop right in for a connection with minimal interference.If the network uses super fast wireless N, you can take full advantage. If the network is still using the slower a, b or g, you still have them covered!
