Sub-THz Wireless Transport Layer for Ubiquitous High Data Rate

Abstract

5G and the future 6G ambitions will be real when wireless “unlimited data” will be available. Multi-gigabit-per-second and terabit-per-second are the new units to measure the data demand of emerging applications such as 8K video, e-health, extended reality, vehicle-to-everything, and many others. Actual wireless networks are based on the fiber substrate that feeds, by fixed access points, a wireless layer for distribution to users at much lower capacity, posing a limit to the introduction of data-hungry applications. To increase the area capacity of the wireless distribution layer, a ubiquitous data source is needed. A wireless layer to transport data at the rooftop level is conceived to wirelessly replicate the data provision of the fiber substrate, with unlimited access flexibility. This new layer is fed by fiber and provides to the wireless distribution layer arbitrarily distributed links for ubiquitous data distribution. The architecture and enabling technology of the proposed wireless transport layer is described.
