Deutsche Telekom (DT) has teamed up with startup firm, Kumu Networks to demonstrate a full duplex 5G in a field trial which took place on its local network in Prague, Czech Republic. DT started its cooperation with Kumu Networks on the 5G technology development after it launched 5G:haus in March 2015.
The trial leveraged self interference cancellation (SIC) technology from Kumu Networks to solve the challenge of sending signals in both directions at the same time over the same wireless channel. The SIC technology is a potential 5G technology that allows in-band full duplex communication. In other words, it solves the challenge of simultaneously transmitting and receiving signals at the same time and on the same frequency, thus significantly enhancing the spectral efficiency.

According to DT, the field trial focused on measuring the stability and robustness of the technology in a variety of challenging, real-world deployment scenarios. The trial successfully demonstrated the potential of the technology to increase spectral efficiency and its relevance as an enabler for 5G networks.

We use field trials to get a better understanding of a technology’s potential and that helps us to identify use cases and applications in the context of 5G. In 5G:haus, we will continue to test and evaluate advanced technologies that pave the way to 5G.
Kumu Networks CEO David Cutrer
We are pleased to partner with Deutsche Telekom as they take a leading role in exploring next generation wireless technologies on the path to 5G standardization. DT’s Prague trials provide evidence that the assumed theoretical advantages of self-interference cancelling radios are indeed feasible.
