Another key takeaway are Ekholm's claims around API momentum, which would finally mean the vendor has something to show for its acquisition of cloud communications company Vonage. In September last year, Ericsson launched a joint network APIs venture — now called Aduna — with several telcos from around the world. Aduna incorporates part of its Vonage business and will ideally bolster the open API vision of exposing 5G network capabilities to application developers as a means to new revenue for telcos.
