CEL-FI’s GO G43 is the most powerful multi-carrier signal booster on the market, offering up to 100 dB of gain on Verizon, AT&T, and T-Mobile simultaneously.

It fills a long-standing gap in the in-building coverage solution space, between consumer signal boosters like the CEL-FI GO G41 and enterprise DAS solutions like the CEL-FI QUATRA 4000c.

100 dB Gain on Multiple Carriers

The CEL-FI GO G43 effectively combines three CEL-FI GO G41 units to deliver 100 dB of gain across AT&T, Verizon, and T-Mobile simultaneously.

This solution is powered by the next-gen IntelliBoost chipset for unconditionally network-safe, high-powered coverage.

Unmatched 100 dB Gain

Unlike most signal boosters limited to 70 dB gain, the CEL-FI GO G43 is engineered and FCC-approved for up to 100 dB of gain, ensuring powerful coverage without compromising network safety. The 30 dB extra amplification means that the G43 can cover the same area as approximately 11 standard boosters.

It is able to do this thanks to CEL-FI’s proprietary 4th-generation IntelliBoost Chip, which dynamically optimizes the boosted signal in real time based on changing network conditions to provide the strongest and most reliable connection possible.

This dynamic boosting ensures users always get the cleanest signal.

Designed for Spaces that Demand the Best

The CEL-FI GO G43 is the ideal solution for larger buildings requiring reliable multi-carrier coverage:

  • High-end residential buildings
  • Condominiums
  • Retail spaces
  • Convenience stores

Future-Proofed for 5G

5G support is more critical than ever, as more carriers open up 5G capability across different frequencies.

Today, the CEL-FI GO G43 supports 4G LTE and 5G-DSS (not quite full 5G) out of the box. It will connect to and boost these frequency bands automatically at setup.

A firmware update in 2024 will automatically unlock full 5G NR support on the same frequencies it uses today. That's proper, no compromises 5G.

Bands Supported Today

AT&T: B2, B4, B5, B12

Verizon: B2, B4, B5, B13

T-Mobile: B2, B4, B5, B12

Bands Supported After Update

AT&T: B2/n2, B4/n4, B5/n5, B12/n12

Verizon: B2/n2, B4/n4, B5/n5, B13/n13

T-Mobile: B2/n2, B4/n4, B5/n5, B12/n12

The G43 does not support n41, n71, or n77 frequency bands used for T-Mobile 5G.

We know that this can get incredibly complicated, so if you have any questions about whether the frequencies you connect on are supported today, or will be in the future, please reach out to our support team.
