Seeing as all WiFi is not created equal.
Is is possible to select wifi frequency preference for the Rover to talk over my wifi network
FCC allows up to 30dbm Tx in U-NII-3 5.8 Ghz and only a max of 23dbm Tx in U-NII-1 thru 2 5.2/5.4 Ghz.
We stay away from U-NII-5 thru U-NII-8 as licensed Part 101 radios can be interfered with and and total take down 5-8.
Additionally the 2.4 Ghz wavelength penetrates minor foliage better than 5 ghz.
When my rover is at the end of my driveway 700 feet from my AP in 5Ghz I see -82dbm (useless) while on 2.4Ghz I see -69dbm.
At what point does the rover jump to LTE 4G as I see my rover attached to my network at -88dbm at times and not jumping over to 4G.
Is the WiFi threshold definable between 5Ghz and 2.4Ghz?
Is the 4G threshold definable?
This all impacts my GPS connectivity.
Thanks for any help

You should be using HaLow and forget your home wifi network. HaLow will penetrate a lot further because it uses 900Mhz bands. There is also a known issue with having WiFi connected simultaneously that could cause some communication issues. It is not recommended to use your home WiFi at all. If HaLow exceeds -83, it will switch to cellular automatically for backup.
As Bryan mentioned, Yarbo primarily relies on a HaLow connection, which operates in the 900MHz range. This provides a more stable and longer-range connection, especially in outdoor environments with foliage or obstacles.
When HaLow is not available, Yarbo will automatically switch to Wi-Fi (if enabled), and if Wi-Fi is also unavailable, it will then fall back to 4G.
Thank you, @bryan.wheeler and @steve , for sharing your valuable user experiences—much appreciated!
Bryan,
I took your advice and uninstalled WiFi to my network to the Rover. Things are running much better.
Negative is that I lost “Smart Vision” when the Rover is on 4G connectivity. “Smart Vision” still functions over Halow.
As stated above “When HaLow is not available, Yarbo will automatically switch to Wi-Fi (if enabled), and if Wi-Fi is also unavailable, it will then fall back to 4G.” Sorry, but it seems that if WiFi is enabled the Rover doesn’t fall back to 4G as it is supposed to. Is this a known issue with Yarbo?
Is it possible to get more information regarding Yarbo frequency management, Tx and ERIP etc.? I’ve been working with Microwave and MMwave frequencies for the last 25 years.
It seems to prioritize WiFi for sure. Yes, this is a known issue. I agree, the choice to restrict smart vision while on cellular is unfortunate. It’s a data cap thing since it consumes a lot of data. But when you need to remote control and it’s not on HaLow or WiFi, it would be nice to be able to override this.
I’d have to defer to @Yarbo-Forum on the specifications.
I’m trying to understand the problems with the Yarbo Rover and WiFi.
Wondering what version of WiFi Yarbo Rover is supporting… it appears that what they are using doesn’t support AP transition (think roaming), jump from one AP to another AP automatically. (An example would be WiFi at the Airport, your connection moves from one AP to the next seamlessly as you move through the Airport.) AP Roaming was added under 802.11r amendment in 2008 and has been incorporated in WiFi since 802.11n came out in 2009. Dual band WiFi supporting both 2.4 & 5Ghz came about around 2009 with 802.11n.
Once my Yarbo Core attaches to a WiFi AP it doesn’t appear to roam to a closer AP with a much better connection nor does it seem to move from 5Ghz to 2.4Ghz even when 2.4Ghz offers a much stronger signal/connection.
What modulation is the WiFi running DSSS or OFDM? If OFDM is it supporting MIMO or MU-MIMO (would be no need for MIMO)? What WiFi standard is running 802.11b / g / n / ac or something else. Guessing it would be 802.11n or newer as it supports dual band.
Also what modulation is the Halow running?
I have 5 outdoor AP’s on the property, so we have good WiFi coverage.
Yarbo must have constricted the WiFi chip they have sourced shutting down the support for “Transition” / AP Roaming or I’m missing something.
