Tri-Band Mobile Phones - Are they the Best?
Author: Daniel Stouffer

Why would you want one of the tri-band mobile phones? Good
question, and this requires us to have a look at how
cellular phones in general work throughout the United
States and the rest of the world.

Cellular phones use radio waves to transmit conversations.
Just as in the case of your favourite local radio stations,
there is a need to regulate, license and monitor the
different frequencies being used. There are a wide variety
of services and systems reliant upon communication via
radio wave frequencies and if this were not heavily
regulated our methods of orderly existence would be heavily
impacted!

From the perspective of cell phones, those that operate on
the more infamous GSM network make use of a variety of
frequencies. In the case of the United States, these
frequency bands are 850 MHz and 1900 MHz. In reality,
transmission occurs in narrow bands either side of the
actual figure. Throughout the rest of the world, on the
other hand, GSM phones operate within the ranges of 900 and
1800 MHz. Phones that work within more than two of these
ranges are now very popular and if you are traveling
internationally tri-band mobile phones are a better choice.

Tri-band mobile phones are a step up from the usual
dual-band phones which we all know and have loved. On the
other hand, when choosing, you must ensure that the bands
features by the phone in question fully correspond with the
bands in operation in the countries that you are visiting,
simply because there is nothing simple about this. For
example, 900/1800/1900 are OK in the US but more ideal
internationally, whilst 850/1800/1900 are typically
excellent in the US but not very good internationally.

Tri-band mobile phones were seen up until the very recent
times as cutting edge. Just as the name suggests, quad-band
mobile phones operate in all of the four above mentioned
frequencies and were seen as pricey. With the advent of 3G
communications - referring to the third generation
development of cellular technology - high-speed data
services have arrived that can utilize yet another band -
2100 MHz.

When selecting one of the tri-band mobile phones, consider
all your options. In addition to ensuring that the phone
you choose operates on the correct frequencies for your
needs, you should decide whether or not to move up to the
latest and cutting edge technologies and effectively bypass
tri-band for quad-band and for 3G connectivity.

Always keep on top of developments in the industry and be
sure that, as the business is so competitive, all the major
players must keep on top of their game and will generally
try to "recommend" the latest in technology to you.
