In a few urban areas, you can use wireless Internet access. To set it up, you attach a radio
modem, about the size of a deck of cards, to your laptop. Wireless service (also called
WAP, or Wireless Application Protocol) made its debut at analog speeds (28.8 Kbps), but
it is being upgraded to 128 Kbps, which is faster than dial-up but slower than most DSL.
Another way to connect to the Internet via wireless is by using a digital cell phone
that includes Internet connectivity. Because these devices have tiny screens, limited
keyboards, no mouse, and slow connection rates, Internet content must be tailored to
them and is usually limited to text.
Some ISPs offer wireless connections to personal data assistants (PDAs) such as the
BlackBerry, Palm, Compaq iPaq, or HandSpring Visor. These small devices have small
screens, but you can use them to read your e-mail and browse the Web. Like cell phones,
PDAs require web content to be tailored to their small screens and their slow connection
rates.
