The Hawking parabolic WiFi dish is a fancy version of our home-brew version to boost your wireless signal.  The one thing Hawking has which you will never achieve, this the cool dish look.  The Hi-Gain Wireless 300N is a dish adapter to your WiFi network which connects via USB and could boost your signal as much as 600%.

The 300N supports b, g and n networks so regardless of your setup, you can put the Wireless-300N to use.  As with any wireless solution security is a big concern and the Hawking unit supports WEP, WPA and WPA2 enccryption - so again, whever your setup the 300N will work.

“Since the dual-antenna is highly directional, they’re also trying to sell it on the idea that you can avoid signal interference by pointing it away from other electronics.  I’m not sure that’s something I’ve ever experienced using WiFi, but I could imagine it might be useful to specifically target a base station in an area with lots of wireless congestion.   – SlashGear“
