A new industry alliance led by Alphabet’s Loon high-altitude balloon technology company and SoftBank’s HAPSMobile stratospheric glider subsidiary aims to work together on standards and tech related to deploying network connectivity using high-altitude delivery mechanisms.

This extends the existing partnership between HAPSMobile and Loon, which began with a strategic alliance between the two announced last April, and which recently resulted in Loon adapting the network hardware it uses on its stratospheric balloons to work with the HAPSMobile stratospheric long-winged drone. Now, they two are welcoming more members, including AeroVironment, Airbus Defence and Space, Bharti Airtel, China Telecom, Deutsche Telekom, Ericsson, Intelsat, Nokia, HAPSMobile parent SoftBank and Telefonica.
