Softbank has cut a check for $1 billion to OneWeb, which plans to build a constellation of satellites to provide Internet access to underserved parts of the world, the companies announced Monday. Helmed by satellite industry veteran Greg Wyler, OneWeb raised a total of $1.2 billion in its latest round of funding. The company will deploy 650 Ku band satellites into orbit at a height of 750 miles, which will offer more than 10 terabits per second of new capacity. OneWeb also will build user terminals containing embedded LTE, 3G, 2G and WiFi.
