My cell phone says it can do "hotspot" or tethering. Would that work as a "booster" for the camera wifi in a long trailer/long truck? (where it is too far for the wifi now)

Eg, I have an iPad on the truck's mirror and the camera at the back of the RV. If I use the cell phone in the front of the RV with the Hopkins app to get the camera's wifi (so it is free that way NOT using "data"),

and turn on the cell's "hotspot", would that give the signal to the iPad it could select as its "network" in the truck for that extra distance?

EDIT--the cell seems to have its hotspot with Bluetooth. I have a question about this idea or another booster in to Hopkins. I will pass along any info.


Almost certainly the phone will not work as a WiFi extender.

The cell phone has three radio systems (that matter here--there are others as well, such as GPS and often an FM radio): the cell phone system, the WiFi system, and the Bluetooth system. Tethering basically connects the WiFi to the cell phone's data connection, with the WiFi unit acting as a hotspot/host rather than a client. (Or, in the case of Bluetooth tethering, it connects the cell phone data connection to a Bluetooth connection.) What you need is a WiFi to WiFi connection/extender, which cell phones are generally incapable of doing; I believe it generally requires additional hardware or at least specialized software.

Yes, my cell phone has "hotspot and tethering" but it lies! It actually has Bluetooth or USB tethering. No hotspot relay as such.

So the USB part works great to my laptop, EG. I can get free hotspot wifi on the cell (or my camera signal), and leave that alone and run the laptop as though it had that hotspot connection.

So you could do that if you had a USB cable that has the plug in for the phone on one end and the different Apple one on the other end or an adapter for that, and long cable run (end to end sets) from the cell in the front of the trailer to the truck's mirror. (Might as well buy a wired camera?)

I have looked at wifi extenders (lots of those) but can't make out how they can pick the right wifi signal to extend by wireless and then relay that to the farther along device. Some(all?) have LAN from the extender back to the first wifi source box and then they wifi from there, (I think)

I am waiting to hear from Hopkins how you can do it. I suppose any 13 year old knows, but I don't! [emoticon] I am just curious anyway, I don't need that in my set-ups.

What you are describing sounds more like an Access Point, not a Wi Fi Extender. All the Wi Fi extenders I have used get plugged into the wall. Then there is either an App or a Web Interface that you connect to the Extender with. Then you tell the Extender what SSID you want to connect to. It connects to that SSID. Generally, you would give the Extender's SSID the same SSID you normally use, however, if you have older Wi Fi devices that don't auto select the strongest signal, you can name the Extender's SSID something different so you know you are on the strongest signal.

With that being said, there are Access Points that can act as Extenders/Repeaters that don't need to be wired. Just be careful as some may require being setup wired directly to the router, then used wireless.

Thanks! Based on that, I found this. Apparently this job needs a "repeater"

My phone has Hotspot/USB tethering/Bluetooth tethering and Ethernet tethering..You can use the hotspot feature to bring up your own network off of your provider like Verizon, if they offer hotspot..This makes it a wifi connection to whatever you connect to it like a tablet or computer..The name of your hotspot appears in the wifi section just like your home network say like Centurylink...

All phones are not equal it seems! Mine is a Nokia 2.1 with Android 10.
The tethering USB is the same cable used for charging it.

If doing that for a time, you would have to disconnect the tethering and do a recharge

Would this thing do the job? It has three modes, but I am confused whether it needs wires as a repeater.

I tried to tether the Nokia 2.1 phone to the iPad using a USB hub to connect the two cables that charge each device, and I couldn't get it to work like I can with the phone and laptop.

I suspect there might be a way and I don't know which buttons to push. While doing that, the Nokia came up with a "hotspot" thing for itself. I don't know if I pushed a button that did that or what.

So the iPad wifi search showed "Nokia 2.1" as a choice, so I got on that and it said it is connected and wanted a password. the cell phone meanwhile was on the Hopkins wifi but I did not have the camera App on the phone.

So it just proved I am a spaz when it comes to gizmos and I quit!

Meanwhile, more on how having the camera in the Class C is such a good thing--
Yesterday I went to a quick oil change place and had to back and fill to get lined up for going in a bay, but there were cars passing behind me going to the car wash. I could not see the cars behind using the side mirrors. To back up I would need somebody out there directing traffic.

Not with the camera! I could see the cars close behind and knew when it was safe to back up. Very neat!

This one should work just fine for you: click. It does have an ethernet port, but that's to use to wire directly to it instead of using wifi, which is a nice feature.

That won't work, you can't split the tethered signal. The USB cable needs to go directly from the phone to the device.

Since you have to connect directly to the camera's SSID, creating a hotspot on your phone isn't going to help you with the camera. However, you can watch this video to show you have to turn on Wi Fi hotspot on your phone.

Good info, thanks!

I don't have anything to add to this, but there are perhaps un-answered questions for those with longer rigs and those with newer trucks with cameras in their removable tailgates.

Over to them if there is anything to add here.
