W-Band

Technical Explanation

The W-band (75 GHz to 110 GHz) sits immediately above traditional millimeter waves. Because it experiences lower atmospheric oxygen absorption compared to the 60 GHz V-band, it is the premier candidate for multi-kilometer point-to-point wireless backhauling between base stations and fiber hubs, delivering fiber-speed 10-40 Gbps pipes across urban rivers, rail corridors, and hilly terrain where laying trench fiber is impractical.

Key Functions

• Low atmospheric absorption profile allowing multi-kilometer wireless transmission links
• Contiguous 5-10 GHz channel bandwidth delivering 10-40 Gbps point-to-point backhaul
• High angular resolution for automotive radar and air-traffic foreign object detection
• Compact antenna integration allowing narrow pencil beams on lightweight street poles
• Standardized by ITU-R WRC for fixed wireless broadband and cellular backhaul services
