Jet Aviation St. Louis and SmartSky Networks will jointly certify and install the first airborne 4G LTE-based wireless Internet network on a Global Express. The resulting supplemental type certificate (STC) will be aimed at the retrofit market, for type owners and operators seeking to take advantage of airborne Wi-Fi that delivers what SmartSky has said is “more than 10 times the typical speed and capacity of existing networks.” Charlotte, N.C.-based SmartSky plans to beta-launch its innovative air-to-ground network, SmartSky 4G, late this year, followed by the rollout of nationwide commercial service next year.
