Ericsson and Drei Austria are collaborating to enhance urban 5G connectivity by testing W-Band frequencies. Their goal is to prove the usage of microwave links in high frequency band especially in densely populated areas, ultimately paving the way for advanced technological solutions in urban environments.
The two partners have recently completed a field trial of W-Band microwave technology, successfully showing its potential as a high-capacity backhaul solution in urban areas where E-Band networks might face congestion.
In dense urban areas, where transport networks face very high-capacity demands, end users will benefit from enhanced 5G performance made possible by deploying W-Band technology to complement the existing E-Band spectrum. This enhancement can improve internet speeds for seamless high-definition streaming, reduced gaming latency and quicker downloads and uploads. Additionally, the increased bandwidth capacity will support emerging applications and services, such as those involving IoT devices essential to smart homes, thereby meeting the growing data demands in major cities.
Wenceslao Garcia de Otazo, head of transmission at Drei sayid, ”By collecting accurate field data about rain, temperature and diverse indicators of the link, like receive signal level, modulation profile, we have been able to corroborate the prediction of the propagation models in 100 GHz with the actual behavior of the link under different weather conditions. After this viability confirmation we are confident about the usage of W-Band Microwave Links as a reliable and very high-capacity solution to connect our 4G/5G sites.”
Operating between 92 and 115 GHz frequencies, the W-Band offers new, free spectrum that complements E-Band networks, particularly in high-density city environments where spectrum congestion may occur. This helps expand transport network capacity and meets growing data demands. The trial, conducted on Drei’s commercial network using Ericsson’s prototype W-Band microwave equipment, showcased the technology’s ability to deliver ultra-high speed wireless communication under real-world conditions, even during heavy rain.
Mikael Öhberg, head of microwave systems, business area networks, at Ericsson said, "The successful trial of W-Band technology offers new opportunities for service providers to enhance their microwave networks and address urban network congestion. W-Band can secure and support the necessary capacity when E-Band falls short, ensuring reliable connectivity and a seamless user experience. This advancement signifies our commitment to delivering next-generation network solutions."
This successful trial underscores Ericsson and Drei’s dedication to pioneering innovative solutions that enhance customer experience and drive the evolution of digital connectivity.
