A recent joint innovation project between Ericsson and Deutsche Telekom successfully demonstrated a millimetre-wave link capable of transmitting data at 40 Gbps.
The live trial, staged at the Deutsche Telekom Service Centre in Athens, marks a clear step forward from today’s typical 10 Gbps deployments toward the eventual 100 Gbps era. The link operated over a 1.4-kilometre hop in the millimetre-wave (E-band) spectrum and used Ericsson’s latest mobile transport solutions, including the MINI-LINK 6352 microwave system and the Router 6000 platform.
An important part of the trial evaluated latency performance to address the tighter requirements of 5G architectures and support low- and ultra-low-latency applications. The tested link delivered round-trip latency of under 100 microseconds, demonstrating that wireless backhaul can play a meaningful role in meeting stringent network latency targets.
Per Narvinger, head of Product Area Networks at Ericsson, commented: “Microwave remains a key technology for mobile transport, meeting the capacity and latency requirements of 4G and upcoming 5G networks. This joint innovation project shows that higher-capacity microwave backhaul will be an important enabler of high-quality mobile broadband services as 5G moves into commercial deployment.”
Earlier, in November, Deutsche Telekom and Ericsson collaborated on campus network solutions for industry customers using a dual-slice approach. That method combines public and private LTE connectivity and can be enhanced with local edge cloud deployments. As part of that initiative, Deutsche Telekom and OSRAM have created prototypes and are testing mobile robotics at OSRAM’s Schwabmünchen factory, where Ericsson will provide system technology for indoor factory coverage and a local core network.
