DUAL-BAND在英语中的意思是什么？

多频段设备

Multi-band device

在电信中，多频带设备是支持多个无线电频带的通信设备。 具有多个通道的所有设备使用多个频率; 然而，乐队是包含许多频道的一组频率。 移动设备中的多个频带支持不同地区之间的漫游，其中不同的标准用于移动电话业务。 在频段宽频分离的情况下，必须提供并行发射和接收信号路径电路，从而增加了多频带设备的成本，复杂度和功率需求。 术语四频带描述了一种支持四个频段的设备：850和1900 MHz，主要用于美洲，以及其他地方使用的900和1800 MHz频段。 大多数GSM / UMTS电话支持所有四个频段，而大多数CDMA / 1xRTT手机不支持，因此只被认为是双频带设备。 一些电话支持国内频率，但只有一个是有限的漫游，这使得它们成为三频手机。

In telecommunications, a multi-band device is a communication device that supports multiple radio frequency bands. All devices which have more than one channel use multiple frequencies; a band however is a group of frequencies containing many channels. Multiple bands in mobile devices support roaming between different regions where different standards are used for mobile telephone services. Where the bands are widely separated in frequency, parallel transmit and receive signal path circuits must be provided, which increases the cost, complexity and power demand of multi-band devices. The term quad-band describes a device that supports four frequency bands: 850 and 1900 MHz, mostly used in the Americas, and the 900 and 1800 MHz bands used elsewhere. Most GSM/UMTS phones support all four bands, while most CDMA/1xRTT phones do not, and so are considered only dual-band devices. A few phones support both of the domestic frequencies but only one foreign one for limited roaming, making them tri-band phones.
