A lot of people meet signal problems when they are talking through their cell phones, for examples when you have something important things to talk with your guest the signal suddenly break off, or you can hear what he says but he can't hear you. That is really a bad situation and that's why the signal booster was invented and it really helps us in having a more fluently talk and bring us convenience in many aspects. Among these different signal boosters, I think the cell phone signal booster for GSM/DCS dual band is particularly amazing. Next just bright your eyes and you will know the details about this device.
Firstly since the cell phone signal boosters work like an antenna to improve the cell phone signal to a maximum degree, thus there is no need for you to leaning out of the window to make or answer a phone call and it would not interference the signal of other devices, like the computer and the television. For example if you are having a talk and you need to search the Internet you can do these two things at the same time.
Secondly the frequency of this device is from 900MHz to 1800MHz, it covers a wide range so you don't need to be anxious about the frequency. The frequency is: Uplink GSM890-915MHz, DCS1710-1785MHz; Downlink GSM935-960MHz, DCS 1805-1880MHz. Then as it is well designed it can be applied into different places for improving the quality of cell phone calling. It can be used in following small regions signal blind or weak signal area, such as underground or semi-underground place of business, basements, underground parking and so on. what's more this device can also be installed in public places such as dance halls, cafes, and theater. But this is just its position advantage.
Thirdly as it is known to us all that most mobile phones are designed with GSM/DCS Dual Band when it is produced, you can use the device trustingly. Besides as the size of it is not big, it's easy for you to carry so when you are in a place that the signal is strong enough you can just need to put it away.

If you know something about this kind of device, you will know that this device is distinguished into different specifications, take the EU and US for example. But in this kind of cell phone booster the problem will not exist, it can not only be used in eastern countries but also been use in western countries as well.
