Nothing is more frustrating than having inadequate cell phone reception in your home or office. You can lose out on an important sale, a business client, or even just the latest neighborhood or family information in these situations. Dropped calls and weak signals limit the use of your expensive smartphone and render much of the technology useless. However, with a GSM repeater, you can amplify a cell phone signal and increase your communication abilities across your home or office. The repeater boosts the weak signal from the base station tower via an outdoor antenna and transmits the signal through your building to maximize signal strength. Use Anywhere There is no limit to the number of devices that the repeater can amplify. It doesn’t matter how many people use a mobile phone within the coverage area, as they will all benefit from the stronger signal. The only catch is that you have to remain inside the area that the repeater covers.
