Different mobile phone networks in different countries operate at different frequencies, which means that if you wish to use your mobile phone outside your home country, you generally need a handset that supports multiple frequency bands. A "dual-band" phone operates on two frequency bands, 900Mhz and 1,800Mhz, allowing you to use it in the UK and Continental Europe. See also Tri-band
(Wireless Phone Feature) A wireless phone that works on both 800MHz digital cellular services and 1900MHz digital PCS (personal communications service) networks.
Phone that can switch between two different bands of frequencies GSM900 and GSM1800.
All those Phones which can switch between two different bands of frequencies are known as Dual band phones. In Europe Dual-band is usually denoted by 'GSM900/GSM1800' capable phone, while in USA it is denoted by 'GSM850/GSM1900' or in a combination of two other bands.
A mobile phone can automatically switch between 900MHz and 1800MHz frequencies, making it able to use many foreign networks. All current Vodafone are at least Dual-Band.
A device that is capable of operating in two frequencies. On a wireless network, dual-band devices are capable of operating in both the 2.4 GHz (802.11b/g) and 5 GHz (802.11a) bands. In cellular phone technology, dual-band devices typically operate in both the GSM900 and GSM1800 frequencies, allowing a greater number of roaming options. (See Tri-mode). close
Operators may transmit on a radio frequency band of 900 MHz or 1800 MHz. Dual-band phones can understand both. This gives you more choice abroad, where agreements cover both kinds of network.
Phones that can switch between two different bands of frequencies. All new phones in the UK are now dual-band, capable of switching between GSM1800 and GSM900 frequencies. Useful for travellers, allowing roaming on a greater number of networks across the world.
Some operators transmit on a radio frequency band of 900 MHz, whereas others use 1800 MHz. Phones, called dual-band, can understand both. This gives you more choice when moving around, where agreements cover both kinds of network. (see also Tri-band)
A wireless phone that is capable of operating on two frequency bands such as the 900 MHz digital band and the 1800 MHz digital GSM band. The dualband phones can be used in Europe, Africa, and Asia.
Refers to a handset that works on the two GSM frequencies in use in North America: 1900 and 850 MHz.
Definition: Mobile phones that are capable of operating on mobile network frequency bands GSM900 and GSM1800 where available.
It refers to cellular phones, which work on both the 800MHz and 1900MHz digital networks
Phones that can switch between two different bands of frequencies. In Europe Dual-band usually means GSM900/GSM1800 capable phone, while in USA it might mean GSM850/GSM1900 or combination of two other bands.
Some operators transmit on a radio frequency band of 900 MHz, whereas others use 1800 MHz. Dual-band phones can operate on both frequencies. This gives you more choice when travelling, where agreements cover both kinds of network.
phone that operates in more than one frequency band is said to be dual-band. Common frequency bands include 800 MHz and 1900 MHz in North America and Latin America, and 900 MHz in Europe and Asia.
A description of a wireless phone that works on two frequencies. In the United States, these are typically the original cellular (800MHz) and newer PCS (1900MHz) frequencies.
A mobile phone that works on two frequency bands - 900MHz and 1800MHz. Just like two heads are better than one, it gives your phone greater capacity, and is particularly useful if you plan to take your phone with you overseas - see 'global roaming', below.
A mobile phone that can operate on two different frequency bands, for example GSM 900 and GSM 1800, which means that you can use it in countries and regions where these networks operate. The N-Gage QDâ„¢ game deck is a dual-band phone. See also Tri-band phone.
