Elve demonstrates breakthrough high-power, full-duplex E-band transmission, enabling 10 Gbps wireless backhaul with unprecedented signal strength
Elve has announced a breakthrough achievement that could reshape the future of wireless communications, unveiling the successful demonstration of a full-duplex, bi-directional wireless transmission operating in the E-band spectrum. This milestone was accomplished using Elve’s advanced Vermillion Traveling Wave Tube Amplifier (TWTA) technology in collaboration with Nokia’s Wavence UBT-m point-to-point radios. The demonstration is being recognized as a historic first for the telecommunications industry, highlighting a major leap forward in high-frequency wireless performance and capacity.
At the core of this achievement is the ability to transmit and receive signals simultaneously over the same frequency band—a capability known as full-duplex communication. While this concept has long been pursued by researchers and engineers, practical implementation at millimeter-wave (mmWave) frequencies, particularly in the E-band (70/80 GHz range), has remained a formidable challenge due to issues like signal interference, power limitations, and hardware constraints. Elve’s success in overcoming these challenges signals a significant advancement in the field.
The initial test results are especially compelling. The system demonstrated more than ten times the transmit power of today’s most powerful mmWave backhaul radios, while maintaining a data throughput of 10 Gbps. This combination of high power and high data rate is critical for next-generation communication systems, where the demand for bandwidth continues to grow exponentially. By dramatically increasing the effective range and reliability of mmWave links, Elve’s TWTA-based solution addresses one of the key limitations that has historically restricted the deployment of these high-frequency systems.
Elve’s Vermillion TWTA technology plays a central role in enabling this breakthrough. Traveling Wave Tube Amplifiers are known for their ability to generate high levels of radio frequency power with excellent efficiency, especially at high frequencies. Traditionally used in satellite communications and defense applications, TWTAs are now being adapted for terrestrial wireless networks, opening new possibilities for high-capacity, long-distance communication links. Elve’s innovation lies in scaling this technology for broader commercial use, making it viable for telecommunications infrastructure.
The collaboration with Nokia adds another layer of significance to this development. Nokia’s Wavence platform is widely used for microwave and mmWave backhaul solutions, supporting mobile network operators around the world. By integrating Elve’s high-power TWTA technology with Nokia’s established radio systems, the two companies have demonstrated a practical pathway to enhancing existing network architectures. This partnership also underscores the importance of industry collaboration in driving technological progress, particularly in the transition toward 5G Advanced and future 6G networks.
One of the most promising implications of this breakthrough is its potential to extend the reach of high-speed wireless connectivity. Traditionally, mmWave signals are limited in range and can be easily obstructed by physical barriers such as buildings, trees, and even atmospheric conditions. By significantly increasing transmit power, Elve’s solution can overcome many of these limitations, enabling longer-distance links without compromising performance. This could be particularly valuable in rural and remote areas, where deploying fiber infrastructure is often costly and time-consuming.
In addition to expanding coverage, high-power mmWave links can play a crucial role in enhancing network resilience. In emergency situations, such as natural disasters, traditional communication infrastructure can be damaged or rendered inoperable. Microwave and mmWave radio links offer a rapid deployment alternative, allowing operators to restore connectivity quickly. With the added advantage of higher power and longer reach, Elve’s technology could enable more robust and reliable emergency communication networks, ensuring that critical services remain operational when they are needed most.
The implications for urban environments are equally significant. As cities become increasingly connected and data-intensive, the demand for high-capacity backhaul solutions continues to rise. High-density deployments of small cells, edge computing nodes, and IoT devices require robust and scalable connectivity solutions. Elve’s TWTA-enabled system can support these demands by providing high-throughput links capable of handling large volumes of data traffic, all while maintaining low latency.
Looking ahead, this proof of concept lays the groundwork for further innovation in wireless point-to-point solutions. Elve and Nokia are expected to continue exploring ways to optimize and commercialize this technology, potentially integrating it into next-generation network deployments. As the industry moves toward 6G, where data rates are expected to reach unprecedented levels and new applications such as immersive virtual reality and advanced autonomous systems become mainstream, the need for high-performance backhaul solutions will only intensify.
Diana Gamzina, Founder and CEO of Elve, emphasized the broader vision behind the company’s efforts. She noted that Elve was established with the goal of unlocking access to mmWave power at scale, enabling higher data rates for both space-based and terrestrial applications. The successful demonstration with Nokia represents a major step toward realizing this vision, showcasing the potential of TWTA technology to transform wireless communications.
This achievement also highlights a broader trend in the telecommunications industry: the convergence of technologies traditionally used in different domains. By bringing together innovations from satellite communications, defense systems, and commercial networking, companies like Elve and Nokia are pushing the boundaries of what is possible in wireless connectivity. This cross-disciplinary approach is likely to play a key role in shaping the future of global communication networks.
In conclusion, Elve’s demonstration of full-duplex, high-power E-band wireless transmission marks a pivotal moment in the evolution of telecommunications. By combining cutting-edge TWTA technology with established radio platforms, the company has not only achieved a technical milestone but also opened new avenues for innovation and growth. Whether it is bridging the digital divide in remote regions, enhancing network resilience in times of crisis, or supporting the data demands of next-generation applications, this breakthrough has the potential to make a lasting impact on the way the world connects.
