openSPOT2 - Ethernet? and WiFi band(s)

Post by JohnF »

Will the openSPOT2 have the option to connect to the internet via ethernet similar to the original openSPOT?

Also, does WiFi support both 2.4 and 5 GHz bands?

Thanks

You can connect the openSPOT2 to an Ethernet network using a wireless AP device. openSPOT2 works on 2.4GHz Wi-Fi channels.

Ok, I guess that means an ethernet cable cannot be connected to the openSPOT2.

Over the years I have seen many problems traced to WiFi interference, especially on the very busy 2.4 GHz band. That is why many people connect directly to ethernet via a cable. Connecting using the 5 GHz band could be an alternative.

I think limiting to 2.4 GHz and no cable possibility are significant issues. Any chance of revisiting this prior to releasing the unit?

The use case is for very low bandwidth links, typically a maximum of a couple of kbits/s. This should not be problematic in dense environments.

The issue is not the bandwidth but the interference from other 2.4 GHz networks or other RF devices in a neighborhood. Resulting problems have been demonstrated by myself and many others.

The WiFi networks should not be a problem as they ought to behave properly regarding access to the spectrum.

I'll grant that non-WiFi devices could be a problem but they will interfere with all WiFi devices not just the hotspot.

Non-WiFi devices can interfere with all devices, not just hot spots - true. But that does not mean you want your hot spot interfered with. 5 GHz would reduce such interference and an ethernet cable would eliminate the possibility.

Lists various sources of interference https://support.apple.com/en-us/HT201542

Regarding other WiFi networks:

https://www.howtogeek.com/209450/how-yo ... -about-it/

The above article does not address the Wi-Fi media access protocol, which can minimize interference, but not eliminate it completely.

Anyway - bottom line: We can argue as to the potential impact on one WiFi network on another, but considering all the other sources of interference, 5 GHz and cable options would be desirable.

I have an enterprise grade commercial cellular router in my vehicle, and everything currently connects via hardwired (shielded) ethernet cables. I could enable the wifi on the router, but I prefer not to. I don't want my vehicle contributing to the wifi noise.

Without some compelling new feature, I won't be buying an openSPOT v2 for in-vehicle use. Maybe for playing around in the shack, but not for mobile use.
