How the System Works
The CEL-FI GO G43 operates by enhancing the signal between your mobile device and the nearest cell tower. The system begins with a high-quality donor antenna installed outside the building. This antenna captures the strongest available mobile signal—regardless of whether it is 3G, 4G or 5G—and delivers it to the signal booster unit installed indoors.
Once the signal reaches the booster, the GO G43 amplifies it using its smart-processing technology and redistributes it throughout the building using internal server antennas. The result is boosted voice quality, faster data speeds, reduced call drops and overall improved mobile performance in every room where the system is deployed.
