Agree with you Jon on “open”, and know the issues well on interference.  

Transparency on spectrum assignment/allocation and what is where is still a huge issue for many countries.  

We are advocating for more transparency and focus re better use of spectrum (aka – knowing what you have and what is where and available).

 

On the 6GHz issue – it seems to be rambling around the WRC prep in the 5G “suite of asks” ; )

The bands allocated to the mobile service between 5150 - 5925 MHz, as well as bands above that range, are also allocated to a number of other services on a co-primary basis. You should be aware that there is strong evidence (i.e. from spectrum monitoring) that shows that the current use of WiFi in this band is causing serious interference into the other services.  So, the future expanded use is probably going to be a hotly debated issue at the WRC-19.”

 

I love this wording:  "strong evidence (i.e. from spectrum monitoring) that shows that the current use of WiFi in this band is causing serious interference into the other services"

 

We have regular interference issues in New Zealand to weather radar, from users of Wi-Fi devices outdoors who operate without the mandated (pesky, performance impacting) radar detect and automatic transmit power control modes that must be used in the 5470-5725 MHz band.

 

I've been involved on a professional basis helping to resolve such issues - so interference is a real, valid threat.

 

However, as countries move to fibre backbones even in remote areas, the need for 6 GHz linking spectrum (called R band in my market) will drop off. Our regulator & existing users will fight to keep unlicensed use away, but in ten years time they won't have a good argument anymore. The spectrum will be better used if it's open.

 

Cheers,

 

Jon
