Coex configuration in SAS

[ssharma]

I configured a few CBSDs with Same freq & Freq reuse group and was expecting SAS to grant same channel to all CBSDs. However, all radios have different channels.   Can all the CBSDs be configured as Basestation or they need to be as CPE? Can you please guide me how to configure a group of radios so that SAS will grant same channel to all the CBSDs.

Hi ssharma!

The SAS can only either approve or deny grants requested by a CBSD. This means that it is ultimately incumbent on the CPEs and the Base stations to request grants on the same channels. Same Freq and Freq reuse groups will change the order in which certain channels are prioritized in spectrum inquiry results, but the devices themselves must request the matching grants.

If you are uncertain how to manually instruct your CBSDs to request grants on certain channels, we would recommend reaching out to the CBSD vendor for further support. It may also be helpful to ask if the order of the spectrum inquiry results is taken into account when the CBSD is determining what kinds of grants it should request from Google SAS.

Kind regards,

James
