SureCall SignalMax Fiber DAS Signal Booster

The SureCall SignalMax Fiber DAS system is a modular, carrier-approved cellular booster solution designed for large buildings that need reliable 5G and LTE signal throughout. It combines the strength of traditional DAS with the simplicity of a pre-certified booster, making it a smart fit for commercial properties, medical campuses, and large industrial spaces. At the core of the system is the Master Unit, which captures signal from outside using a high-gain directional antenna. That signal is then boosted at the strongest point using SureCall’s Extended Range Technology™. From there, the signal is transmitted via fiber optic cable to one or more Remote Units inside the building. These units rebroadcast coverage through multiple ceiling-mounted antennas, pushing fast data and strong voice connections into offices, hallways, and other hard-to-reach areas. Because it uses fiber as the system backbone, SignalMax can deliver signal across long distances with minimal loss, which makes it ideal for multi-level buildings, warehouses with high ceilings, or multi-building campuses. The system is designed to scale easily: the standard configuration supports up to 50,000 square feet, and with added components, coverage can reach up to 500,000 square feet. There’s no need for retransmission agreements or carrier coordination. SignalMax is pre-approved for Verizon, AT&T, T-Mobile, and other carriers that operate on FCC-certified bands. It’s fully 5G-compatible, supports all major LTE bands, and can be monitored in real time via the SureCall Cloud IoT platform. Whether you're fixing dropped calls in a concrete-heavy hospital wing or expanding wireless coverage across a large manufacturing floor, SignalMax delivers reliable performance with a future-ready design and the tools to scale with your space.
