What Is a Cell Booster?

In a distributed antenna system (DAS), a cell booster, also known as a cell repeater or signal booster, is a device that is used to improve cellular signal strength in areas with weak or no cellular coverage. It is typically installed as part of a DAS infrastructure to enhance the performance of cellular networks in buildings, stadiums, campuses, or other large indoor or outdoor spaces.

A cell booster in a DAS consists of three main components: an outdoor antenna, an indoor amplifier, and an indoor antenna. The outdoor antenna captures the weak cellular signals from the nearest cell tower, and sends them to the indoor amplifier. The indoor amplifier then boosts the signals to a desired level of strength and sends them through the indoor antenna for distribution within the building or facility. The boosted signals help improve voice call quality, data speeds, and overall cellular coverage, allowing users to have better connectivity and performance on their mobile devices.

Cell boosters in DAS are designed to support multiple cellular frequencies, such as 2G, 3G, 4G, and even 5G, and can work with various cellular carriers and technologies. They should be installed by professional installers to ensure proper placement, configuration, and compliance with relevant regulations and standards. Cell boosters can be an effective solution for improving cellular coverage in areas where building materials, distance from cell towers, or other obstructions may cause weak signals, helping to enhance the user experience for cellular communication.
