AVANCE L3 and L5 are comprehensive in-cabin Wi-Fi systems that operate on Gogo’s ATG network. They are designed specifically for business aircraft and offer enhanced connectivity applications. The AVANCE platform is innovative in business aviation because it’s a software-centric approach rather than being hardware centric. That means the AVANCE systems are flexible and scalable, even customizable for the user – especially the L3 which can be configured at three different levels to best fit the user’s needs. The L5 is more robust for activities such as streaming video and email with large attachments.

The Wi-Fi equipment developed by Gogo Business Aviation has a dual-band router, meaning it can operate on either the 2.4 or 5 gigahertz (GHz) frequency which delivers improved in-cabin performance for a superior passenger experience.
