Baicells 430H Outdoor CBRS Setup Guide
Updated over 5 months ago

Initial Connectivity Setup

To start, we will be placing the Outdoor small cell inside near a window and next to your network gear to confirm a set of preliminary checks. This validates that things are working before the outdoor small cell is deployed to its permanent location where it may be difficult to access. Before setting up your Outdoor Small Cell, first setup your FreedomFi or Powered by FreedomFi gateway (like the Bobcat Bobber 500) by following the steps in the FreedomFi Gateway Setup Guide

Step 1: Connect POE+ Injector

Connect the included POE+ Injector to a wall socket or a UPS. Extension cords(especially daisy-chained) are not recommended.

Step 2: Connect Ethernet cable to POE+ Injector

Connect the ethernet cable to the port labeled LAN on the POE + Injector

Step 3: Connect the Ethernet cable to the Gateway

Connect the other end of the ethernet cable to the port labeled eNB1 the FreedomFi Gateway. Two additional CBRS small cells are supported on the eNB2 and eNB3 ports.

Step 4: Connect POE+ Cable to the POE+ Injector

Connect an outdoor-rated ethernet cable to the port labeled “POE” on the POE+ injector. The length of this cable should be long enough to reach the permanent location where you want to deploy the small cell. This will be the only cable that you need to route outside.

Here is an example: Outdoor Rated Cable

Ethernet cables must be 330ft/100m or less in total length.

WARNING! Ensure that you are installing your POE in a watertight enclosure/environment and that water is unable to travel down the CAT cable and into your POE. This can cause permanent damage which is not covered under warranty.

Step 5: Connect POE+ cable to the Outdoor Small Cell

Open the waterproof door on the Outdoor small cell by unscrewing 3 screws.

Connect the other end of the outdoor rated ethernet cable to the Outdoor small cell.

For now, let's place the outdoor small cell near a window with clear view of the sky so it can get gps lock. This is something we’ll need to access the dashboard. We will be moving the outdoor small cell to a permanent location at a later point, but for now, it just needs to be placed somewhere that it can get a gps lock.

Step 6: Verify Connectivity Status

Visit your small cell dashboard by utilizing the Official Helium Dashboard and logging in with your Helium Wallet.

Outdoor Small Cell Install & Registration

To start, make sure you select a good place for the Outdoor small cell. Obstructions will decrease coverage. CBRS signals have less range than LoRa. Similar to Wi-Fi they can be weakened or blocked by obstacles like walls, trees, and buildings. To capture the most data you can, you want your small cell to point towards a populated area, a place with a lot of people and phones e.g. a park, a playground, an outdoor cafe/coffee shop.

For the purpose of improved coverage area, it is recommended to mount your outdoor small cell as high up as reasonably possible. This often means on a roof, or near the roof line of a building. Roof mounting examples for a home or small business:

  • Flat Roof: Non- penetrating roof mount filled with cinder blocks

  • Angled Roof: J-Bar mounted to the facia

Requirements: The outdoor small cell will require installation CPI approval before it can go on air and allow users to connect.

The CPI process requires the following:

  • Installation parameters must be shared with FreedomFi to get CPI approval

    • Height with 2 to 4 photos to document accuracy

    • Azimuth angle with 1 photo to document accuracy

    • Elevation angle with 1 photo to document accuracy

Note: How to get and submit this information along with sample photos will be covered in the small cell registration section below.

Small Cell Registration

To enable the outdoor small cell, you’ll need to complete the CPI flow and get approval. The process starts with registering the small cell location.

To register the outdoor small cell, you’ll need the following information along with photos to prove it.

  • Height

  • Azimuth Angle

  • Elevation Angle

  • Street Address of installation

Step 7: Recording your Radio Height

You will be required to submit the height of the installation and a photo to verify it. Here are some ideas on how to get the height:

  • Ask a contractor or building manager about the height of your roof.

  • Get the height of the home/building by looking at it in Google Earth Pro.

  • Please follow the steps here.

  • Use a tape measure and measure the height directly from the top of your roof

Take a photo that shows the radio and the ground. Sample Verification photo:

Step 8: Recording your Radio Azimuth Angle

Azimuth is a fancy name for the compass direction in which the center of the antenna is pointing. Please utilize the free NOAA Mobile Magnetic Declination calculator for this measurement.

  • Navigate to the NOAA website to get a compass up NOAA Mobile Magnetic Declination Calculator

  • Important! Ensure you allow NOAA to utilize your device location to ensure an accurate declination reading.

  • Choose the “Compass” option in the lower-left corner

  • Important! Place the phone on top of the small cell, so the TOP of the phone (the part that goes to your ear on a phone call) is pointing in the same direction as the antenna.

  • Take a picture of the compass direction

The sample picture is showing azimuth angle of 109 degree.

Warning! CPI submissions utilizing any apps/tools other than the NOAA Mobile Magnetic Declination to calculate the Azimuth or CPI submissions with location services disabled on NOAA will be rejected.

Step 9: Recording your Radio Elevation Angle

The elevation angle is a fancy name for “is it pointing up or down from level.” The reference point is the middle of the antenna. To ensure consistency across all applications, we ask that you please utilize the following free app to measure & record your elevation accurately.

Bubble Level

Steps to collect this photo:

  • Open the recommended app above on your device.

  • Place the phone on top of the small cell. All certified outdoor cells all have a flat portion of the top surface that is perpendicular to the front of the antenna and will hold a phone.

  • Take a picture of the elevation angle

The sample image is showing 3 degrees of down-tilt angle using the Bubble Level app.

Warning! Ensure you are placing your phone directly on top of the flat portion of your 430H small cell exactly as seen in the sample photo and utilizing the recommended apps, failure to do so will result in CPI rejection

Step 10: Register your Radio

Now that you have the small cell information and photos, you will need to submit them for CPI approval. Access your small cell dashboard by heading to the Helium Dashboard:

  • Login to your Helium Dashboard

  • Scroll down to “Attached Radios”

  • If you have more than one radio connected, make sure the serial number matches the radio you are trying to register.

  • Click “Register Radio” in the bottom left corner

  • Follow the wizard to fill out the form and add photos

  • Submit the information

  • Wait for Approval

Step 11: Verify your Radio is online

Once you get the CPI approval notification, your small cell should be ready to go. To check, navigate to the small cell Dashboard and verify that the registration status is approved, and the statuses are all Green.
