Most work on 5G radio standards is driven by 3GPP, with the IEEE and the WiFi community remaining a separate, and even competing, wireless path. However, most stakeholders would welcome convergence between the two, and this was once promised as a by-product of ‘5G’ – through common interconnectivity frameworks and APIs, if not an actual unified physical layer. The body with the power to drive this type of convergence is the ITU, which later this year will define which standards officially count as IMT-2020 or 5G. In February, CTOs met to discuss the ITU’s 5G programs and make recommendations, which go far beyond the radio, and put forward a top-to-bottom architecture change, together with a redesign of wireless network protocols…
