Gogo’s Nationwide 5G Network Construction Halfway Complete July 22, 2022 BROOMFIELD, Colo. Gogo Business Aviation’s (NASDAQ: GOGO) nationwide 5G network construction is halfway to completion with the 75th site now online. Gogo 5G remains on budget and on schedule to launch in the second half of 2022. “Getting to the 50% mark for our 150-tower 5G nationwide network in a matter of months is an incredible accomplishment by our team,” said Mike Rupert, vice president of network operations for Gogo Business Aviation. “We have a team of network experts that has been working hard to bring the 5G network to life, building sites across the country, and that work will continue into the fall.” Gogo has been regularly updating the market on its 5G network build progress with a deployment map on its website: https://business.gogoair.com/gogo-5g/. “We’ve been testing our network and we’re pleased with the results we’re seeing,” said Dave Glenn, senior vice president of customer operations. “Gogo 5G is going to deliver on everything we’ve promised to the market.” Gogo 5G is expected to deliver ~25 Mbps on average with peak speeds in the 75-80 Mbps range and has been designed to deliver high throughput with very low latency to address the increasing demand for data-heavy interactive services like video conferencing.
