In recent years, the consumer electronics industry
has seen a steady trend
toward convergence. In the
past, users carried several
separate devices--from cell
phones to portable music
players, PDAs, video players
and cameras--in order to
meet all their
communications and media
needs. Today, a single
product can perform all
these functions, reducing
the amount of money spent by
consumers and the amount of
space taken up by the
products needed to perform
the tasks.
Advances in technology
have made this possible.
Media storage hardware has
increased in capacity but
not in size, enabling more
content to be saved in the
same amount of space. Power
management solutions have
extended battery life.
Connectivity methods are
robust and reliable. User
interfaces are now so
intuitive that anyone can
operate any device.
There are, of course,
some drawbacks associated
with a single communications
and media solution, the most
prevalent of which is amply
expressed by asking, "What
do I do if something happens
to my phone?" Not only is
the ability to receive calls
lost, but all contacts and
calendars, e-mails,
music,and videos are no
longer at your fingertips.
Fortunately, because all
information stored on a
device like this can be
backed up on a computer, it
is a simple matter of
getting a replacement device
and syncing with it.

So, what happens if you
get a new phone (either
because the last one is no
longer usable or because it
was simply time to get a new
one)? I wanted to test how
long it would take to
transfer simple, common
media examples to various
popular multimedia phones.
The use case included one
CD's worth of music, an
episode of a television
show, and a feature-length
movie. Because I started
this testing around
Halloween, I went with a
theme:
CD: "Once More With
Feeling" by the cast of
Buffy the Vampire Slayer
(49.7 Mbytes, composed of 22
songs ranging in length from
00:00:20 to 00:06:56)
TV show: "Buffy the
Vampire Slayer, Season 3,
Episode 1" (275.9 Mbytes,
with a duration of 00:44:52)
Movie: "Buffy the Vampire
Slayer" (552.5 Mbytes, with
a duration of 01:25:24)
This sample seemed to
represent my media habits.
While waiting for the bus,
I'd listen to a few songs.
Once on the bus, I'd watch a
TV episode. When flying, I'd
watch a movie. The media I
selected also represent the
various sizes of content
that users typically
transfer.
The four phones tested
were the Apple 4-Gbyte
iPhone, the RIM BlackBerry
8120, the Sony Ericsson
W910i Walkman, and the
Motorola Razr V2 (I also
wanted to duplicate the
experience of most
consumers). I used the
provided sync software when
able and tested direct file
transfer as well. Each test
was conducted at least
twice. The computer used was
a 2-GHz Intel Core 2 Sony
Vaio laptop with 2 Gbytes of
RAM and USB v2.0, operating
Windows XP, Service Pack 2.
This test is not designed
to take the phone features
into account other than to
mention some prominent and
relevant ones. I intended to
create a fairly academic
report of file transfer
times.
Here's a rundown of the
phones' basic features and
market positioning. The
table at right shows my
results.
Apple 4-Gbyte iPhone
The Apple iPhone (see:
Inside the Apple iPhone)
is a very popular phone
right now. According to
Apple, more than 1 million
have already been shipped.
Semiconductor Insights
looked at the components
that made up the iPhone when
it was first released. The
user interface, not the
components, has been the
driving force behind the
success of the iPhone. The
3.5-inch widescreen display,
access to iTunes, and Wi-Fi
and Edge connectivity
position the iPhone as a
multimedia device. It
operates on the GSM network
and offers Bluetooth.
The iPhone I used was
updated to v1.02, and I used
iTunes v7.4.3.1 for the
transfer. Because the iPhone
did not appear as a drive on
my computer, I was not able
to test direct file
transfer.
BlackBerry 8120
The
BlackBerry products have
long been favorites of
business-oriented consumers.
The ability to check and
send e-mail anywhere
anytime--which can prove
addictive--has earned these
phones the moniker "CrackBerry."
The 8120 was released in
Europe, operating on the GSM
network. It also has
connectivity through Wi-Fi
and Bluetooth.
The BlackBerry 8120 is
available in Europe but is
not yet available in North
America, although the
planned North American
release of the BlackBerry
8130 is imminent. When
transferring to the
BlackBerry 8120, I used both
the provided media manager
software and direct file
transfer.
Sony Ericsson W910i
Walkman
According to Sony, the
Walkman player turns phones
into powerful portable music
devices. The phone only
comes with 35 Mbytes of
memory, which is also used
for the phone's software,
and supports a 4-Gbyte Sony
Memory Stick Micro (M2).
I had some difficulty
transferring the files to
the Sony Ericsson
W910i. The provided
software didn't seem to make
matters easier, so for my
first test I used direct
file transfer. In the charts
depicting the test results,
this method is not
represented, in order to
keep some sort of relative
scale of test results. The
phone came with a memory
card reader, so the second
test was performed by
transferring content through
that external source.
Fortunately, this second
method of downloading
content was much faster,
although it requires users
to have a card reader on
hand.
Motorola Razr 2
The
Motorola Razr 2 is the
next generation of the
popular Razr phone. Its
sleek design has influenced
the look and feel of a
number of other phones
currently on the market. The
external display features a
touchscreen for easy
interactivity. The phone has
512 Mbytes of internal
memory and supports Micro SD
cards.
Because no file transfer
software was included with
the Motorola Razr 2 phone to
which I had access, I
transferred my files via
direct file transfer.
Please remember that the
values for the Sony Ericsson
W910i reflect the
performance of the external
memory card reader and that
direct file transfer rates
were omitted to maintain
relative scale with the
other phones. Surprisingly,
the BlackBerry 8120
transferred files faster
than any other phone tested,
despite its low name
recognition in the
multimedia-device market in
comparison with other phones
that overtly sell themselves
as multimedia phones.
Why did the BlackBerry
perform so well? The answer
lies inside . . .
The device behind the
BlackBerry's fast transfer
rates is the Cypress
CYWB0124AB west bridge
peripheral controller. West
bridge products directly
connect peripherals,
creating fast transfer
tunnels without loading the
main processor. Instead of
routing files from the
computer through the phone
processor to the storage
device, the west bridge sets
up a tunnel running from the
computer directly to the
storage device.
This practice carries
with it a number of
advantages, including
significant increases in
transfer speeds. That can be
a blessing when uploading a
significant amount of
content onto a phone (such
as when it is first
purchased or has been
formatted).
This speed bonus is also
a plus for those who like
changing their phone's
content regularly. Mobile
systems today have
sufficient memory to store a
movie or two, some CDs, and
typical phone data like
contact information and
pictures; but having the
same movies on the phone all
of the time can get
wearisome, especially for
frequent travelers. Being
able to replace phone
content quickly is therefore
a big selling point.
Transferring information
without activating the
central processor conserves
battery power. Granted, the
device is plugged into a USB
socket and is therefore
recharging anyway. But
during content transfer, the
amount of time that it takes
to charge the battery is
lessened.
The point of this
exercise was to make readers
aware of transfer speeds.
Think of the time saved when
transferring 4 Gbytes of
data to a phone. According
to the average transfer
rates shown earlier, the
iPhone would take 23
minutes, the BlackBerry six
minutes using its media
manager and five minutes
when using direct file
transfer, the Sony 210
minutes using direct file
transfer and 15 minutes via
the external memory card
reader, and the Razr 19
minutes.
The difference in times
required by the various
phones may well be the
difference between drinking
a cup of coffee before
heading out of the house and
planning out, well before
leaving, the content you
want available on your
phone.
