The price tags of the OrangePi 3G/4G IoT are incredible. I want to consider them inside my project to not just reduce the costs but also increase the simplicity and reliablity. I need at least 1.4 Mb/s uplink (2 Mb/s is excellent) for my design.
Is there anyone familiar, help me to find out more about their abilities? I want to use them for streaming live data.
Thanks

Hi, I'm going to attempt to answer your question, but  there is missing information.
Different Countries use different frequencies and bands and some may not be available in your country.

However 1G,2G, 3G use a single frequency. The fourth generation mobile network 4G is superior because
it transmits and receives on multiple frequencies simulataneously. If you have intereference  on one band or
frequency the others will generally get through.

For example, here in the UK, 3G was very poor but 4G is superb and reaches many places in your house
and even one level underground in some car parks, were 3G did not work.

So I would go for OrangePi 4G IoT

The specification of the Orange Pi 4G
http://www.orangepi.org/Orange%20Pi%204G-IOT/

Below are the bands that the Pi 4G can use:

GSM: 900/1800 (850/1900 optional)
WCDMA:        B1/B8 (B2/B4/B5 optional)
TD-CDMA
CDMA2000
FDD-LTE:        B1/B3/B7/B20 (B2/B4/B17optional)
TDD-LTE:        B38/40/41B


What you need to check is what frequency bands are available in your Country and location, to help you
here is a starting link:
http://www.4g-lte.net/about/lte-frequency-bands/

The download and upload speed on 4G varies with the signal, for example in open space
and near a window I get 90Mbps download and 30Mbps upload. In a kitchen between
a cooker and fridge (full metal objects) I get   30Mbps downstream and about 15Mbps
upstream. This is still superior to home wifi and other signals apart from 5G.

As the Orange Pi 4G  uses DDR3 memory the limiting factor is likely to be the speed of the
SD card, so use the highest class of card possible.

Depending on your application  full HD 1920x1080p resolution  uses  only 3Mbps to download or upload.
If youre adding a sound layer, subtitle layer and audio desciption this uses around 4Mbps, so well witin
device capabilities proving that the 4G signal is good.

Again you did not say what you are streaming but most streams are compresses which is why they can use
lower bandwidths.
Hope that helps

Different Count ...

Thanks for your reply.
I want know to if there is any hardware limitation inside these boards. As you know, commercial modems have different uplink/downlink speed based on their architectures. Hence I wanted to know if these boards' modems have any limitations (aside from their CPUs and RAMs). As I mentioned, I just need about 2 to 3 Mbits/s bandwidth and I probably will use ffmpeg (which is not finalized). All I wanted was to be sure that both of them support such a consideration.

Are you going to install a camera on your front door? Then you should contact your local providers directly. Not all of them provide a good download speed, which is very important for streaming video from a security camera. I myself have long understood that I cannot influence this moment, and taking satellite Internet is unprofitable. As a result, I ended up with the fact that there was a duplicate fiberglass doors for the terrace - https://www.elegantentrydoors.ca/entry-fiberglass-doors/ I chose a model that has a roller mechanism so I can tuck them away while I'm at home and push them in when I'm about to leave. This way I feel much safer.

When it comes to the maximum uplink and downlink speeds of the OrangePi 3g/4g IoT boards, it's essential to consider the specific requirements of your IoT project. These versatile boards offer varying connectivity options, allowing you to tailor your device's performance to suit your needs, whether you're monitoring data from a remote weather station or managing smart appliances like cooker hood fitters near me,. Depending on your chosen cellular network and configuration, you can achieve reliable data transmission speeds, making these OrangePi boards a valuable asset for a wide range of IoT applications.
