Maybe you are a business man who are in touch with you, the customer must remain, even if you are traveling from one part of the world to another, or maybe you’re just someone who is on all the news and even round will be updated. So you are looking for a perfect phone for your needs and private, is not it? But what kind of band is called?

In the United States GSM services two frequency bands, while there are also two different frequency bands, which were used by them in other parts of the world. Faced with this dilemma has some of the largest manufacturers of mobile phones such as Nokia, Siemens, Ericsson and Motorola, a phone that can work on all four frequency bands commonly referred to as quad-band phones developed.

As for this band? We try to understand more. Use radio waves

Mobile phones to transmit conversations. These radio waves at different frequencies. . Consider this interesting disc is made of different frequencies, the use of various types of radio services

GSM mobile phones in four different frequency bands

* 850 MHz (824.2 to 848.8 MHz, Tx used.; 869.2 to 893.8 MHz Rx)

* 900 MHz (880-2 – 914.8 MHz Tx; 925.2 to 959.8 MHz Rx)

* 1800 MHz (1710.2 – 1784.8 MHz Tx, 1805.2 to 1879.8 MHz Rx)

* 1900 MHz (1850.2 to 1909.8 MHz Tx, Rx 1930.2 to 1989.8 MHz)

Although 850 and 900, 1800 and 1900 numbers are obviously close, a phone that works in one frequency band unfortunately can not operate in the frequency band next to it, unless included as a specific frequency band more. In contrast, if you tuned the VHF radio to have a radio station on 98.1 MHz, you can never, of course, to feel what is happening on another channel to 98.3 MHz when you tune the radio again. Do you understand? This is actually how the frequency-band phone will work.

Previously, the U.S. only 1900 MHz for the GSM phone. But over the years, there has been a growing number of GSM service in the 850 MHz band, simply because this type of service used in rural areas in general, since it has a better range than the 1900 MHz band is, however, was also used in urban areas, especially if the cell phone company with a frequency parts, not used in the 850 MHz band and not to use the remaining frequencies in the 1900 MHz band has.

On the other hand, use it as the United States to GSM, a few other countries with close ties to the United States began chosen to copy the United States and use the same frequencies used in the United States. In fact, almost without exception, all international countries that are non-US international frequency bands using the 900 MHz service.

So, what frequencies are needed when traveling abroad?

If you want to use the phone only at the international level, you must decide whether you want to use the phone in the countries, the international frequencies or in countries that use the frequencies of the United States, or both. But in all current 900 MHz band has been in use worldwide and 1800 MHz only give extended coverage in the countries which are also 900 MHz

However, if you want the phone to be used only in the U.S., only one dual -band phone that is both 850 MHz and 1900 MHz band is only a single phone with 1900 MHz to cover almost as good anyway.

In short, if you use the phone in the U.S. and internationally to plan the best solution is a quad-band phone is working on four bands, the band 850/900/1800/1900 Mhz.
