RN - CBRS Installations

CBRS Steps in the RN Web UI

Under Setup, carefully verify the geography and orientation parameters described below.

  • Latitude: Geographical latitude of the RN in decimal notation.

  • Longitude: Geographical longitude of the RN in decimal notation.

  • Tilt: Vertical (elevation) angle of device installation as measured from the horizon (0 degrees).

  • Height: For CBRS RNs, this is the installed height above ground level (AGL).

  • Azimuth: Horizontal angle of device installation as measured clockwise from north.



The latitude, longitude, and azimuth can manually be entered here or from the RN’s Device page in TCS, but the Tilt, and Height, can only be configured from the RN’s Web UI. 

For 5 GHz RNs, the latitude and longitude are only necessary for an accurate Map View in TCS and the Height, Tilt, and Azimuth are optional. However, for CBRS RNs, all five of these parameters are required. Remember, the Tilt and Height can only be configured from the RN’s Web UI.


Troubleshooting Note: It is especially important to make sure the latitude and longitude parameters are entered correctly because incorrect coordinates will have the biggest impact when this device registers with the Spectrum Access System (SAS). 

For example, in the graphic on this page, the longitude listed is -98.56300354… This will place the RN in Downs, Kansas, which is a valid location for the SAS. However, if the longitude is entered as a positive integer (missing the minus sign in front), you are asserting this RN is in the Gansu province in China somewhere near the Gobi Desert. This is obviously not a valid location for a CBRS device from the SAS point of view and will result in the RN continuously sending a registration request to the SAS and the SAS continuously rejecting the RN.

For CBRS models, after Submit Changes is clicked, an Installation Parameters pop-up will appear. Verify the installation parameters are correct, then enter your CPI ID and click Confirm.


Check that the number entered is your CPI-ID and not your CPI Certificate number.



For CBRS units, the GPS coordinates, tilt, height (AGL), and azimuth must be configured and verified by a CPI upon installation. Until this is done, the RN will be connected to the BN in restricted mode and will not pass data or be visible in TCS.

CBRS Steps in TCS

For CBRS installations, the CPI should edit their user profile in TCS to include the CPI-ID and upload their CPI certificate. The CPI Certificate is a .p12 file.



Take care that you enter the CPI-ID number in the CPI-ID field and not the CPI Certificate number. For example, note the similarities between a Google .p12 file name and the related CPI-ID: 

GOOG-000365_2295819 (name of .p12 file) 

GOOG-000365 (CPI-ID) 

The FCC OR-ID and SAS fields must be configured for CBRS installations. These parameters are under Network Configuration. Edit the Operator page to configure these parameters.



Note: The FCC OR-ID is assigned to customers by the Spectrum Access System provider (Google or Federated Wireless).
