Chapter 1. Understanding Intel Centrino ... > The Benefits of Built-in Wi-Fi

The Benefits of Built-in Wi-Fi

Of course, Centrino technology is optimized for use with mobile computers. And it is built for wireless networking from the ground up a great advantage over previous generations of mobile computers. There are no extra cards sticking out and no dangling antennas. Centrino-based laptops are sleek the antennas are built right in. Bottom line, there is less stuff to carry around, wireless reception is great, your laptop is easier to use, and the battery lasts for hours.

Alternative Wi-Fi Solutions

If you use a mobile computer that does not incorporate Centrino technology, chances are it was not built from the ground up with Wi-Fi capabilities. This isn t the end of the world, but it means that a Wi-Fi “card” needs to be added to the mobile computer. The card might have been added at the factory, but if not, you ll need to configure it correctly. In either case, one of the expansion slots of your computer will be used. (So you can t use it for anything else.) In addition, the card might stick out of the side of the mobile computer, if it doesn t use an internal card, making its form factor more awkward. Figure 1.2 shows a notebook computer with an external Wi-Fi card seated in the expansion slot.
