Screenphones are consumer-oriented devices
combining a telephone with a basic Web browser, letting people easily connect
to the Internet. They can be divided into three broad product categories:
■ Low-end screenphone products (current
price range $100–$150) – These use a very small LCD display and provide only
the most basic access to limited Internet content such as text e-mail or text
news. They usually allow only three to four lines of information on the screen.
■ Midrange screenphones (current price
range $199–$399) – Midrange devices have a larger screen with a miniature
keyboard. These products provide robust interactivity with limited Web browsing
capabilities, through the use of ADSI (Analog Display Services Interface)
scripts.
Vertical applications such as home banking
and information-based service such as stock quotes, news feeds, weather,
e-mail, sports scores, and more can be accessed from the Internet. In some
cases, a user can create e-mail and browse the Web on a miniature keyboard. The
variation in cost is due to features such as digital answering machines,
cordless handsets, etc.
■ High-end products (current price range
$400+) – These have a 7- to 8-inch color screen with graphics and touch-screen
capabilities that allow e-mail, and Web browser (IP) functionality. Other,
smaller applications include address books and notepads, as well as support for
advanced network services such as caller ID and voicemail.
They have a touch-screen, retractable
keyboard, and smart card reader. They are intended for quick Web-based
transactions such as ordering pizza or downloading stock quotes. They usually
include speakerphones and feature two-line capability, allowing for
simultaneous Web browsing and voice communications over standard telephone
lines.
Some of these also include digital
answering machines. The first generation of this phone will connect with a
56-Kb/s modem that shares one phone line for Internet and regular phone calls.
Future models will be able to handle two lines, as well as ADSL (using phone
lines) high-speed connection techniques.
The Internet screenphone bears some
similarity to other consumer Internet appliances, such as TiVo, that are intended
to shield users from some of the complexities of the Internet. TiVo boxes
automatically dial into the Internet over a phone line, but, in the future,
TiVo plans to achieve high-speed Internet access using cable TV infrastructure.
