Basics of a Smartphone




-
Smartphones

are hand
-
held devices that use cell
-
phone network technology to perform a variety of tasks
involving data transfers


-

These tasks include:



-

phone calls



-

text messaging



-

web browsing



-

email



-

listening to and downloading music files



-

file transfers



-

viewing and transfer of multimedia



-

supporting the addition of user
-
developed software applications



-

GPS navigation





-

The current industry standard for the wireless networks that support
smartphone

technology is 3G


-

The maximum transfer speed for 3G is 3 megabytes per second, which equates to a 15
-
second download time for
an mp3 file that contains a 3
-
minute song


-

Phones running on a 3G network can support broadband applications such as video conferencing, receiving
streaming video from the internet, and the instant download of attachments from emails





-

Some
smartphones

also have the ability to connect to Wi
-
Fi networks, which have faster internet speeds than
cell
-
phone networks


How the Technology Operates



Inside a Smartphone





The Hardware of a Smartphone


Smartphones

run on 100
-
624 MHz processors. These processors could not come close to powering a
desktop computer, but for the somewhat limited tasks that a
smartphone

performs those processors are
very effective.


The processors used are ARM processors, which have tens of megabytes of onboard memory. MP3 players,
routers, printers, and other technologies use these processors.


Smartphones

also contain computer chips to support functions that include (among others) real
-
time web
browsing, playing music files, and the sharing of video and picture files.





The Software of a Smartphone


Smartphones

software is arranged as a “stack”.


The software stack contains:


Application suite
-

used for simple applications like menu screens and message inboxes


Application execution environment
-

application programming interfaces, instituted recently so tech
-
savvy phone
-
owners can create their own programs


User interface framework
-

deals with what is actually seen on the screen of the phone


Kernel
-

manages the hardware (drivers and management systems)


Middleware
-

libraries of software that enable applications like security, web browsing, and messaging





Smartphone Operating Systems


The operating system is the software in a
smartphone

(or any other type of computer) that manages the
hardware and the other software


Some particular
smartphones
, such as the
iPhone

and Blackberry, run a phone
-
specific OS, but many phones
use the
Symbian

OS

Background Information

-
Cell phones used to just be used for calls

-
The technology then developed so texting and
other data transfers could be done on wireless
networks

-
The first
smartphone

was created in 1992 and
debuted at an information technology conference

-
The definition of a
smartphone

is not completely
agreed upon in the wireless technology industry


Smartphones
: Good?





Helps you stay organized


always able check/make appointments


always available to chat/email/video conferencing


better information sharing. ability forward emails,
create and edit spreadsheets and word
documents.

viewing

attachments to emails


provides faster communication through a faster web
access then older mobile technology.


also provides full

web access

(
vs

the slimmed down
mobile web,

WAP).


Smartphones
: Bad?




Price

: Many
smartphones
, like the Motorola Q, aren't much more
expensive than a regular phone, but many are.
Treos

are ghastly
expensive, and the Sidekick 3 isn't cheap, either. The Apple
iPhone

is also
much more expensive than regular handsets. Additionally, you will also
need to upgrade your cellular plan to include data service for your
smartphone
, which can run anywhere from $30 to $80 per month,
depending on the carrier and the speed of the service. Not cheap.





Complexity
:

Of course,
smartphones

won’t be as simple as regular
handsets. Even making voice calls on a
smartphone

can be trickier than
on a regular phone. If you aren't planning to use the "smart" features
regularly, you may waste a lot of time trying to find your way around
some frequently confusing menus, a huge problem with Windows
Mobile devices like the Treo 700w. Although people like to have a fancy
phone with them as a status symbol, is it worth it if you’re only going to
use it for calls and texts??


The Final Decision



Smart phones are awesome!
-



nothing's
perfect; there are problems with

all
new technology


-

a moderate usage provide us with..
.



-

fast communication



-
increase
in
productivity
