What is the 4G used for?

Support & Solutions General Issues
1

So I’ve had many issues, even trying to begin to map anything. Saw the new update with the SIM and 4G slot.
“Replacing the SIM Card with Your Own”

“The SIM card is installed inside the rover, located within the battery storage compartment. Currently, we provide 2GB of free data per month. However, if you rely heavily on 4G service and prefer to use your own SIM card, you can replace the pre-installed one.”
So heavy use. Yarbo can run normally on 4G? This is to get updates? I’ve had mine on when I unpacked, and loaded the APP. APP saying it’s on. No usage is being shown. Can anyone break down what the 4G is for? I’m lost I think. GPS is faulting my usage correct? Can I still map with 4G? If I took this Yarbo to a friends to try to demo, without the DC. Can I set it up to run on 4G? Thanks for any help.

Yarbo will tell us more, I’m sure, but it seems to fall back to 4G if it’s can’t connect to the data center via halow or wifi. It uses this as part of its RTK location awareness. If you’ve got good GPS sats but it’s still complaining about lack of GPS, check your halow signal strength and make sure it’s got data from the DC.
I’m inferring this from my unit’s behavior after a rollover accident broke the halo antenna off. I was impressed it was able to still mow, and it continued for several days until it ran out of LTE data and couldn’t connect to the DC. It complained about GPS, not a data center connection. I managed to attach a new antenna and it got its DC connection back and then went right back to mowing.
In general, it won’t use 4G at all if it has a halow connection. It’s a backup and doubles up as a way to report it’s location if someone tries to remove it from your lawn.

Thank you for your question—happy to provide some clarification regarding the use of 4G and connectivity in Yarbo’s system.

The 4G connection is primarily used to facilitate RTK (Real-Time Kinematic) data transmission between the rover and the data center (DC), which serves as the RTK base station. Accurate RTK positioning relies on a continuous data link between these two components.

Yarbo supports three communication methods between the rover and the data center, prioritized as follows:

  1. HaLow – the default and preferred connection
  2. Standard Wi-Fi (2.4 GHz or 5 GHz)
  3. 4G cellular network

HaLow provides long-range, low-power connectivity and typically works within 100–500 meters, depending on terrain and interference. When the HaLow signal becomes weak (e.g., below -82 dBm, shown in the Diagnostics page), the system will automatically fall back to Wi-Fi or 4G, if available and properly configured.

If you haven’t seen any 4G data usage, that’s completely normal—it simply means HaLow has remained stable, and no fallback has been necessary.

Regarding mapping:

Mapping and navigation require the data center, as it provides both RTK correction data and serves as the coordinate origin for all map data. Without the data center, accurate positioning and mapping cannot be performed, even with a 4G connection.

Additionally, we do not recommend taking Yarbo to a different location (such as a friend’s house) for demonstration purposes unless you’re prepared to reset and remap everything.

:warning: Reinstalling or relocating the data center will erase all existing maps and configuration data, as the coordinate origin would be reset. This action is irreversible and would require you to set up your entire yard map again from scratch.

If you have any further questions or need help with setup or connectivity, feel free to reach out—we’re here to assist you.

How does it handle multiple APs on the same network. I use ubiquiti, have my property well covered. I don’t have much but an occasional pause while roaming and streaming video. However I’m wondering if there are settings that need to be tweaked for better connectivity.

@Ryan - Suggestion: Remove the rover from your WiFi network, and don’t even worry about it going from AP to AP. That WiFi connection on the rover is not needed, and it can cause issues. Often the issues present themselves as GPS problems due to the Data Center and rover having to renegotiate communications about GPS.

Diagnose Tools - Wi-Fi, and there you can disconnect the rover from your WiFi.

Thanks, do they all come with Sim card preinstalled?

They do and include 2Gb a month for free

Right now it’s so disconnected those diagnosis tolls don’t even load. Waiting for my 4am teams meeting
