Microwave Backhaul Ascending Toward the W-Band

NEWS


Ericsson, along with Deutsche Telekom and Cosmote, has demonstrated the viability of the W-band (92 – 114 GHz) for multi-gigabit wireless backhaul for 5G and beyond. The trial successfully established a 1.5 km, W-band wireless hop that achieved data throughput of 5.7 Gbps over 1.5 km and exceeded 10 Gbps over 1 km hops.

This trial indicates positive progress on the required backhaul evolution to accommodate growing 5G traffic and enable higher capacity use cases. While fiber will continue to be the de facto solution for modern networks, wireless backhaul can be a great alternative for deployments where fixed wireline would have to overcome commercial and logistical challenges (i.e., rural areas). That being said, a couple of factors—spectrum and backhaul technology—would need to be addressed/utilized to facilitate the increased adoption of fixed wireless backhaul in future networks.
