Wasn't DFS created to mitigate this: https://en.wikipedia.org/wiki/Dynamic_frequency_selection https://en.wikipedia.org/wiki/Dynamic_frequency_selection
Been used in a few countries fine from what I know of and I live near Heathrow airport and use it to no ill effect. Though don't have the details of what bands they just opened up and how they compare with other countries and any impact.
[EDIT ADD]
Whilst looking this document had a nice insight into the middle band usage globaly https://mma.prnewswire.com/media/1136543/5G_Mid_Band_Spectrum_Global_Update.pdf?p=pdf https://mma.prnewswire.com/media/1136543/5G_Mid_Band_Spectru...
Page 5 has current regions bandwidth assignment in that block and does seem that from that the USA is slow compared to other countries in assigning that band for consumer usage.
Page 6 has a nice visual showing the use/proposed use comparing regions - most insightful.
- adriancr 6y agoDFS is usually disabled and you have options to enable it via "I am outdoors" flag. Guess how many people enable it.
- Zenst 6y agoIn some regions it is compulsory. USA being one.
- karteum 6y agoDFS is only for wifi, and only with regards to co-channel interferences with radars. Here (as far as I understand) the main issue is the airborne receiver blocking (i.e. catching energy from other bands) because of poor filtering on the receiver side.
