Enterprise 4G & 5G Mobile Signal Coverage Solutions
Poor mobile reception inside commercial buildings can lead to dropped calls, slow data speeds, and communication issues that affect staff, customers, and operations. Fixtel delivers advanced in-building mobile coverage solutions using the powerful CEL-FI QUATRA 4000e Active DAS Hybrid platform.
Designed for enterprise environments, the QUATRA 4000e provides reliable 4G and 5G signal coverage throughout offices, warehouses, hospitals, apartment buildings, shopping centres, underground car parks and large commercial facilities.
