The firm is aggressively targeting existing users of Gogo by offering up to $50,000 in rebates when they trade in their Gogo systems for a SmartSky install. The two rivals also have been in the courts battling over patent infringements. SmartSky's ground network is running a mix of 5G and LTE technologies, giving it actual measured peak download speeds of more than 20 Mbps and uploads of over 18 Mbps. While the ATG battle rages on land, its dominance ends over water where connectivity is not available. Viasat, and others who use a GEO satellite array, may not be able to compete with ATG latencies but have greatly enhanced their network by launching Ka-band satellites in addition to their Ku-band constellation, boasting typical download speeds of 30 Mbps or more and peaks of up to 90 Mbps, and global availability.
