Is there a difference between Intel Centrino and Wireless Lan 802.11b/g which one is better.?
I had this very question when I bought my laptop, and the Intel advertising (on their website) doesn’t help matters. The other commenters are correct in saying that the CPU and the Wireless technology are separate. However, “Centrino” is a package deal that Intel sells includes the wireless capability integrated into the circuitry with the CPU (and some other components). This is specifically designed to be a low-power-consumption option for Laptops. So, the answer is that if you have Centrino, you have 802.11 wireless built into the machine. The latest Centrino models appear to have at least dual-mode (802.11b/g) if not tri-mode (802.11a/b/g) technology to cover all the current wireless protocols.
