A recently conducted joint innovation project between Ericsson and Deutsche Telekom successfully demonstrated a millimetre wave link with a data transmission rate of 40Gbps.

The live trial, which was organised at the Deutsche Telekom Service Centre in Athens, is a breakthrough moment in the evolution from today’s 10Gbps reality toward the 100Gbps future. It was arranged over a hop distance of 1.4 kilometres in the millimetre wave (E-band) spectrum, which included a technical setup consisting Ericsson’s latest mobile transport technology including Ericsson’s MINI-LINK 6352 microwave solution and Router 6000.

During the trial, the focus was also on the stricter latency requirements in the 5G network architecture to support low latency or ultra-low latency use cases. The round-trip latency performance of the link tested was less than 100 microseconds, confirming the positive contribution of wireless backhaul technologies to satisfy network-specific latency targets.

Per Narvinger, head of product area networks at Ericsson, said: “Microwave continues to be a key technology for mobile transport by supporting the capacity and latency requirements of 4G and future 5G networks. Our joint innovation project shows that higher capacity microwave backhaul will be an important enabler of high-quality mobile broadband services when 5G becomes a commercial reality.”

Back in November, Deutsche Telekom worked with Ericsson in offering campus network solutions to its industry customers based on a dual slice approach that combines and integrates public and private LTE connectivity that is often enhanced with a local edge cloud deployment. Deutsche Telekom, along with OSRAM, is making prototypes and testing mobile robotics solution at the latter’s factory in Schwabmünchen, which will receive system technology from Ericsson for indoor factory coverage and local core network.
