Deutsche Telekom and Ericsson achieve 40Gbps Over Wireless Backhaul

German telecommunication provider, Deutsche Telekom and equipment solutions provider Ericsson has conducted data transmission tests using millimeter wave (E-band – 70-80GHz) and achieved 40Gbps wireless backhaul transmission rates over a distance of 1400 meters. This is a milestone achievement in access technology that would redefine the transmission technology business.

The trial was conducted at the Deutsche Telekom Service Center in Athens over a hop distance of 1400 meters in the E-band spectrum utilizing the setup based on Ericsson’s mobile transport technology.

The experiment proved that the wireless backhaul connections are able to provide enhanced customer experience in the 5G era, that is equivalent to the fiber.

The Deutsche Telekom and Ericsson were initially targeting a transmission rate of 10Gbps using the millimeter wave but then went on to demonstrate the capability of the millimeter wave link to transmit 40Gbps. This is four times greater throughput compared to their own target and the current solutions available in the market.

The trial experiment and the results make Ericsson and Deutsche Telekom the first companies who could achieve high bit rate transmission over millimeter wave. It is an important milestone in the evolution from today’s 10Gbps reality toward the 100Gbps future The partners achieved four times greater data throughput compared to current commercial millimeter wave solutions to prove the commercial viability of future wireless backhaul technology.

The trial test also focused on the stringent latency requirements in the 5G network architecture to support low latency or ultra-low latency use cases. 100 microseconds was the round-trip latency performance of the link This value is in compliance with the stringent requirement for wireless backhaul technology to satisfy network-specific latency targets.

A high-performance transport connection is key to support the high data throughput and enhanced customer experience in next-generation networks. Optical fiber easily achieves this, but fibers are not the only backhaul for many of the providers.

The joint demonstration of “fiber-like” performance is an outstanding achievement in wireless technology to prove that such transmission rates are possible with wireless backhauling/X-Haul solutions. For Deutsche Telekom, the trial offers confidence to extend its portfolio of high-capacity, high-performance transport options for the 5G era.

The trial gives an indication that along with fiber, the microwave will also continue to be a key technology for mobile transport by supporting the capacity and latency requirements of 4G and future 5G networks. The project shows that higher capacity microwave backhaul will be an important enabler of high-quality mobile broadband services when 5G becomes a commercial reality.

Deutsche Telekom had recently increased the broadband speeds that would benefit approx. 2.3 million subscribers in Germany. Read the news here: T Com Upgrades Networks to Enhance Broadband Speeds
