    January 2017 : GAFASAT

    In the first of the Technology Topic podcasts, Geoff Varrall explores the developing involvement of the GAFA (Google, Apple, Facebook and Amazon) quartet in terms of network ownership and added value. He also discusses the changing dynamics of the 5G and satellite supply chain, how technology is reducing CAPEX and OPEX in the satellite industry, increasing CAPEX and OPEX in the mobile broadband industry, and the related implications for future competitive positioning.
