WiFi transmission power and range specs?

Hi, I am interested in the transmission range for the Amiga over 2.4GHz WiFi but I can’t find any specs in the documentation that describe antenna gain/transmission power.

Can anybody link information that would help? I am working with Amiga + Intelligence kit.

Thanks,

Hello,

At the moment we do not have the WiFi power and dB levels collected and published. We did not design the brain as a long range WiFi device because of the dependencies of use-cases and environment.

When needing large WiFi coverage we have focused our efforts on access points and/or mesh networks providing the range needed for the environment. This is partially due to the environment dramatically changing WiFi requirements.

In some of our applications we have also added cellular hotspots. Both general purpose cellular WiFi hot spots, or rugged units that can plug into the Switch on the machine. In some applications this is more practical than adding WiFi infrastructure.

Even internally practical testing is the first step to understanding the needs of your application and environment. At the moment we will not be changing the antenna or WiFi module built into the Brain, so evaluation is the most best path forward.

I understand you still might have questions on this topic and please ask here. If you can also explain your goals and use-case more @kylecoble and myself might be able to provide more support.

Thanks for replying! I am seeking clarification regarding this bit of documentation:

One does not simply “build-in” WiFi, there has to be an additional WiFi module. It is my understanding that the Nvidia Xavier (Brain) only supports 1 Gig ethernet out of the box. So what is the hardware or the specs of the hardware added to enable wireless connection?

I understand that I am pushing the envelope of intended operation, but for every engineer who wants to do a bit of napkin math to approximate performance I thought it would be helpful to see if I could get some more information to supplement the documentation.

I should add that in this case I am interested in the napkin math because:

  1. For my project the equipment and operating area isn’t available for testing until we thaw out in the spring. :slight_smile:
  2. It would be helpful to see if theoretically the Amiga has the broadcast strength to reach our WiFi base station after receiving.

Hi @evergreen-project ,

Sorry for the delay. We are working on getting the wifi module specs to you. We are playing a bit of catch up after the World Ag Expo last week, and just want to make sure you know this request is not forgotten.

Thank you for your patience.

I apologize for the delay, trying to play catch up now.

This is the WiFi module on the existing Jetson boards. This is subject to chain and selected by our supplier.

Here is also the antenna

As mentioned before we have used this in a very general sense. If constant connectivity is needed in application we usually move to external cellular modems, mesh networks, and/or external high gain WiFi systems. The POE switch offers a good place for this networking capability.

Great, thanks! Appreciate it.

Quick summary of the information in links above for anyone else rolling through here:

  1. Farm-ng Amiga supports 2.4 GHz and 5 GHz networks, 867 Mbps max, 802.11n
  2. Supports Bluetooth 4.2 and BLE
  3. AC 8265 Transmit Power: 15.6 dBm (bluetooth), 20 dBm (2.4G), 22.8 (5G) from EU style approval certificate here
  4. Antenna Gain: 3.3 dBi @ 2400 GHz, 4.9 dBi @ 5100 GHz, and 6.5 @ 7125 GHz

Much of this information is, as @TravisT said, far less important than testing in the real world, but helpful if you want to run the numbers through a WLAN range calculator.

Or if you wanted know your Amiga supports 2.4G, 5G, and bluetooth.

Hey,
Thanks for the quick summary, I would like to know if the Amiga supports 5G

I don’t believe the Amiga supports 5G cellular. If you are looking at the last line of my post above, that was just an abbreviation from 5Ghz WiFi. Sorry about that.

9

Can I connect a 5G wifi to it?

10

Yep! Has worked well in my experience.

11

what is the difference between 5g cellular and 5G wifi?
Sorry I am new to this

hey Guys,

@Rutvij_Wamanse, I thought you were referring to 5 GHz wifi networks. There are pretty much wifi signal that any device can use, it is just a more modern network standard, so some devices are not ready to use it. Nowadays, most modems have both (you probably seen some networks with the suffix 5GHz when searching for wifi networks with your phone). The Brain is capable of using these networks, as we as the 2.4 GHz.

Now, 5G in the mobile network context refer to the 5th generate of LTE networks, which is essentially a mobile phone network provided by the well known mobile carriers. Again, more modern standard then the 4G networks and its predecessors. The Amiga Brain does not support this.

One way to use a 5G LTE network would be to use a modem, like the ones carriers sell as their plans. These devices create a “bridge” between the 5G LTE network and a local wifi network. The range is usually limited, but as long as you keep the modem close to the Amiga, it works fine.

any links for 5G modems for the amiga

14

I think the constraint is more on which carrier works better on the area you are. They will usually provide you the modem they are currently using and even replace when a newer harware is available.

Maybe try using a phone’s wifi hotspot as a test before chosing one?
