Gogo completes first 5G end-to-end call

Gogo (GOGO) confirms that GCT Semiconductor (GCTS) has successfully completed the very first end-to-end call using its next-generation 5G technology. The call, which took place on June 16, 2025, confirms the Gogo 5G chip is fully functional and ready to move through the final phases of integration. The technology milestone represents a critical stage in Gogo’s journey towards delivering 5G air-to-ground connectivity to North American operators. GCT Semiconductor delivered the new 5G chipset to Airspan, a provider of network deployment solutions and Gogo’s 5G partner, in May. The successful integration of the microchip, which is smaller than a thumbnail, into hardware and software allowed Airspan to configure and support the end-to-end call. The connection, set-up in the lab, confirms the 5G technology is ready to transition to the next phase of integration testing and performance optimization.
