Future high-speed communication networks based on millimeter-wave (30-300GHz) technology will be more robust and efficient in delivering extremely high speed, high quality video, and multimedia content and services thanks to the results of a ground-breaking research project.

The recently-concluded project was a collaboration between Huawei Technologies and IMDEA Networks Institute, the Madrid-based research body pioneering many technologies that are being deployed in the new 5G landscape.

Dr. Joerg Widmer, the Principal Investigator on the project and Research Director at IMDEA Networks, describes the challenge his group tackled.

So, High Frequency (HF) communications, like mmWave systems which offer the speed and capacity that 5G and 802.11ad-standard Wi-Fi networks require, demand directional antennas in order to overcome the resulting attenuation.

This results in high signaling overheads, since both ends of the communication have to continuously update their antenna steering as nodes move and blockages interrupt the line-of-sight path.

These problems are avoided in low frequency (LF) networks, with their rich multi-path environment and much lower attenuation rates."
