How does CEL- FI Go G41 Signal Booster work?
Description
The CEL-FI GO G41 Smart Signal Booster is a next-generation, carrier-approved solution engineered to deliver outstanding mobile coverage in environments where indoor signal is weak or completely unavailable. Designed for 3G, 4G, and 5G services, the G41 provides up to 100 dB of gain far exceeding the performance of traditional repeaters ensuring crystal-clear voice calls, stable data connectivity, and smooth performance across all major Irish networks.
Purpose-built for indoor applications, the G41 offers reliable coverage of up to 1,500 m² right out of the box when used with the supplied outdoor and indoor antennas. For larger or more challenging building layouts, the system can be easily expanded using additional indoor antennas or extended cabling, providing seamless coverage across multiple rooms, floors, or complex structures. This scalability makes the G41 suitable for a wide range of environments, including large homes, small to medium-sized offices, warehouses, workshops, agricultural buildings, rural homes, and properties with thick walls or metal construction that typically block mobile signal.
The CEL-FI GO G41 is fully legal for use in Ireland because it is a network-safe, carrier-approved mobile signal booster that complies with ComReg regulations. Unlike generic repeaters, which are illegal to operate without a licence, Cel-Fi products use advanced protection features that prevent interference with mobile networks. The G41 is specifically designed to meet Irish regulatory standards for power, stability, and network integrity. This ensures it can safely improve mobile coverage for homes, offices, and commercial buildings. When purchased from an authorised Irish supplier, the Cel-Fi GO G41 is 100% legal and approved for nationwide use.
How It Works
The CEL-FI GO G41 captures the weak mobile signal available outside your building and delivers strong, usable coverage inside. The process is simple:
- The outdoor antenna receives the best available mobile signal from nearby network masts.
- The G41 booster unit amplifies this signal using advanced, carrier-approved technology.
- The indoor antenna(s) distribute the boosted signal throughout your rooms or workspace, providing consistent voice and data performance where you need it most.
