On the Constellations Podcast, we'll discuss emerging direct satellite-to-cell phone technology and how it could dramatically alter the relationship between satellite and terrestrial networks. With us today is Chris Quilty, Partner in Quilty Analytics, who will discuss the financial, technical and regulatory implications of direct satellite to cell phone connectivity now being explored, and in some cases deployed, by SpaceX and T-Mobile, Globalstar and Apple, and Iridium among others. Chris will discuss the different business models: using a mobile network operator's (MNO) existing spectrum or using spectrum assigned to Mobile Satellite Services (MSS). Listen as he explains how this technology could impact cellular backhaul revenues and conclude with his thoughts on the challenges ahead for direct satellite to cell phone connectivity.
