SureCall 5X Max Commercial 5G/4G Cell Phone Signal Booster for Large Buildings & Campuses

The SureCall 5X Max is a high-power commercial cell phone signal booster engineered to improve indoor 5G and 4G LTE coverage in large buildings, warehouses, and multi-building campuses. Built for demanding signal environments, the 5X Max provides scalable coverage from 20,000 up to 75,000 sq ft, delivering stronger voice, text, and data performance for all major North American carriers including Verizon, AT&T, and T-Mobile.

Massive Coverage with EXTENDED RANGE TECHNOLOGY™ (ERT)

The SureCall 5X Max is the first commercial booster to feature EXTENDED RANGE TECHNOLOGY™ (ERT), which overcomes outdoor cable signal loss by amplifying cellular signals at the strongest point outside the building. The result is improved tower reach, faster data speeds, and a larger indoor coverage area compared to conventional boosters.

• Up to 20,000 sq ft coverage with 2 indoor antennas
• Scalable up to 75,000 sq ft with up to 12 indoor antennas
• Designed for complex floor plans, large facilities, and campus deployments

Best-in-Class Performance for 5G & 4G LTE

The 5X Max significantly improves voice calls, text messaging, and mobile data on 5G and 4G devices. Performance-leading technologies help maintain a strong phone-to-tower connection even in weak-signal environments.

• 2XP® Technology doubles uplink transmission power back to the cell tower
• SureIQ™ automatically optimizes incoming signals to prevent shutdown and maintain peak performance
• Supports 5G & 4G LTE phones, hotspots, and connected devices
• Optimized for urban, suburban, and rural installations

Dual Interior Ports for Scalable Indoor Coverage

The indoor host unit includes two high-power interior antenna ports—like having two boosters in one enclosure—delivering increased gain and power over single-port boosters. The system is scalable with additional components to support up to 12 indoor antennas for expansive coverage.

Full IoT Cloud Access & Remote Monitoring

The SureCall 5X Max includes complete remote monitoring through the SureCall Cloud interface, enabling off-site management, real-time signal visibility, and faster troubleshooting. This is ideal for integrators offering managed services and recurring revenue options.

Installer-Friendly LCD Display

An integrated LCD display provides real-time system status and parameters to help installers optimize performance, reposition antennas, and troubleshoot quickly during setup.
