Wi-Fi Technology

Remember when you had to plug your computer (or computer’s modem) into
the wall in order to access the Internet? I do. Thanks to Wi-Fi, though,
even though your modem still needs to be connected via wires, your
computer doesn’t. Wireless Internet access makes laptops and other
Web-connected devices infinitely more useful because they can be used
from anywhere within range of the wireless access point (the Wi-Fi
router that is plugged into the wall).

And in some places, thanks to municipal wireless networks, and new
technologies such as WiMAX and cellular data networks, you may not need
anything to be plugged into the wall to access the Web. Thanks to the
Wi-Fi technology.
