4G & 5G Cell Phone Signal Boosters and DAS (Distributed Antenna Systems)

A commercial cell phone booster is a professional-grade system that amplifies weak cellular signals within large offices, warehouses, schools, hospitals, and other business environments. By enhancing 4G LTE and 5G coverage for all major carriers, these boosters eliminate dropped calls, boost data speeds, and ensure uninterrupted wireless communication—critical for productivity and safety. For more details on how these systems work and comply with regulations, see the FCC’s official consumer guide on signal boosters.

Yes. Intelli’s advanced cell phone boosters and hybrid Distributed Antenna Systems (DAS) are engineered for universal compatibility—including support for AT&T, Verizon, T-Mobile, and regional or international networks. Our solutions are scalable and can be custom-designed for offices, medical centers, manufacturing plants, educational campuses, retail complexes, and more. Regulatory requirements and system guidelines are further explained by the FCC.

A Distributed Antenna System (DAS) is a sophisticated wireless infrastructure solution using multiple strategically placed antennas to distribute cell signals throughout large or multi-level buildings. DAS enables seamless 5G and multi-carrier coverage even in challenging environments and supports high user capacity.
