It is of single chip design and uses digital CMOS technology which allows it to operate with less power. It gets better reception due to its extended range abilities. Overall its just a higher end card than the Intel cards in the Dell laptops. Also I have seen a few sites online selling them here in the US but you pay a lot more.
Some people find the Intel cards ok and work fine for them however others dont and have all kinds of problems. For example I have used my 9300 with the Intel 2915 card at 7 locations which all used different wireless hardware. 3 of these locations the Intel would connect only at 1Mbps and well thats useless! The other locations it would connected and give me full 54Mbps but sporadically drop to 1Mbps for a few minutes, then return to 54Mbps again. Uninstalling drivers, changing drivers and anything dealing with drivers DOES NOT HELP!
Honestly I dont care why they work better as long as they do. I'm so tired of my connection dropping to 1Mbps. Unfortunately I have to wait until after christmas to place my order.
FiReBReTHa.. I will be ordering 2 of these after christmas for both my 9300 and the wifes new 700m which she doesn't know about yet
