Mobile technology has opened a lot of doors for communication in places that weren’t always possible. Today, you can use your cell phone just about anywhere. For this reason, it can be even more frustrating when you experience a weak signal in your home or office. The best solution for this problem is to install a GSM repeater in the area where you are experiencing low reception. What is a GSM Repeater? A low signal can be caused by a variety of conditions, such as interference, thick walls or other obstructive structures, or the distance from the cell tower. Since cell phones operate by transmitting radio waves from one base station to the mobile unit, the GSM repeater acts as a middle receiver, in which the signal is amplified before being sent to the cell phone.
