RN - Setup (Configuration)

Initial device configuration is done by clicking Setup from the navigation pane. The following items are in the Setup section:


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. 

To modify a setting, make the change then click Submit Changes. For a 5GHz RN, configuration changes are immediately applied.

For CBRS RNs, click submit changes for the Installation Parameters pop up with a prompt for the CPI ID and confirmation.


CBRS devices must have these parameters set and verified by a certified CPI. Until that happens, the RN will be connected to the BN in restricted mode. This means it will not pass data or be visible in TCS.

  • Operator ID: Set the operator ID. Note: An RN will only connect to BNs with the same Operator ID.

  • Search for BNs: Clicking Search for BNs will cause the RN to disconnect and search for a new BN.


    Clicking Search for BNs will disconnect this RN and interrupt subscriber service.

  • Radio State: Indicates if the radio is searching, initializing, calibrating, or up.

  • Before an RN connects to a BN, it will undergo a process of searching for a viable BN signal. The list of detected BN signals will be represented by the Search Metric as the RN scans through the supported frequencies. After the RN completes the scanning process, it will enter the Initialization stage with the BN that has the highest Search Metric. The RN will then go through the Calibration stage before the connection to the BN is established.


    It is important not to move the RN while it is in the Calibration stage.

  • This entire process can be repeated by clicking Search for BNs.

  • Alignment Metric: Once the RN is connected to a BN, the Alignment Metric will appear. The Alignment Metric is a unitless dial that ranges 0-30 with 30 being best. Multiple factors are used to derive the alignment metric value. Once the RN is aimed, the dial responds in real time and may be used as part of antenna aiming during installation.


    A minimum value of 12 is recommended for a usable link.

  • BN Serial: The serial number of the BN to which the RN is connected.

  • Hostname: RN hostname.

  • Data VLAN: The RN’s Data VLAN can be entered here. Remember that this VLAN is between the RN and the BNG.

  • 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: Installed height above ground level (AGL).

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

Bringing Up a New RN

The following is a general guide for the process of bringing a new RN into service:

  1. Confirm the unit powers up.

  2. Confirm the Operator ID.

  3. Check the RN has established connection with a BN.

  4. Optimize the alignment metric.

  5. Input latitude, longitude, height, tilt, and azimuth.

  6. Confirm that the subscriber connected at 1 Gbps full duplex.
