I've been looking into the differences between 5 GHz and 6 GHz for fixed networks, and one thing that stands out is that choosing a frequency isn't just about getting higher speeds.
5 GHz is still a practical option for many deployments, especially when the existing network has enough capacity and interference is manageable. However, as subscriber numbers grow, finding channels can become more challenging.
This is where 6 GHz may be worth considering. It can provide access to spectrum where permitted, but it doesn't automatically mean better range or stronger signals.
Before upgrading, I'd want to check a things:
- How congested is the existing 5 GHz spectrum?
- Are the link distance and line of sight suitable for the proposed setup?
- Would better channel planning solve the current problem?
- Can the backhaul handle the additional traffic?
- Are the required frequencies and equipment permitted under local regulations?
I found this guide for understanding the trade-offs between the two frequencies: 5GHz vs 6 GHz, for Fixed Wireless Networks

**For those who work with networks, what would you check first before moving from 5 GHz to 6 GHz?** Would you upgrade the network or introduce the new frequency only where additional capacity is needed?
