Carrier-agnostic Solution: FCC & Carrier Approved

The Top Signal Fiber DAS 4400 Master Unit (MU) receives available outside cell signal, amplifies it, and transmits it via fiber-optic cable to up to four Remote Units (RUs). Each RU amplifies the signal again and rebroadcasts it inside your building through one to four antennas.

This active cellular DAS system allows you to stay connected in areas where cell service is poor, where your building’s construction materials interfere with signals from local cell towers, or in other situations where cellular service is not available inside your facility.
