What is an IoT Network?

The Internet of Things


The Internet of Things (IoT) describes a network of everything that is connected to the internet, from something as small as a toy or sensor, to as big as a train.


While IoT devices were a new concept just a few years ago, the concept of IoT has spread to almost every aspect of our lives, from medical services to smart home devices, even to agricultural industries across the world. Advancements in Technologies such as cloud computing, big data management, machine learning, artificial intelligence, predictive analytics, and mobile technologies have allowed IoT devices to offer better privacy, increased stability, and streamlined user experiences.



Why are IoT Networks Important??


IoT devices, since they are connected to the internet, are capable of communicating with devices across the entire network and with outside services, such as the TP-Link Cloud for both Kasa and Tapo devices. Connecting these devices to the internet, not only provides increased control and functionality, but the anonymous data collected can be used to optimize connections, communicate statistics (energy monitoring), or even create alerts/notifications. In industrial applications, IoT devices allow companies to better monitor, track, and predict changes that may occur on a larger scale, such as how the agricultural industry can even track the detailed humidity, solid moisture, and temperature across their property in order to provide the best-growing conditions for their crops.


IoT devices, while providing invaluable experiences to our lives and smart homes, can also use a significant amount of bandwidth or crowd your home network. By placing all these devices on a separate network, you are freeing up your network for the devices where you want the best connection, such as your phone or streaming device.


Automation Efficiency

If you have ever attempted to create automations with your Smart Devices on a congested network, you will know that the overall performance, speed, and reliability at which the Automation is performed can be heavily affected or varying. By placing your Smart Devices on a designated IoT network, you can be sure that your devices can effectively communicate with each other to provide the best connections possible. This will also create additional bandwidth on your main wireless network that your streaming devices and phones can now take advantage of.


Simplified Setup

IoT networks can also simplify the setup process for your smart devices as a separate and easier-to-input password can be used to connect the devices. IoT networks also provide methods for changing the bands and security used by these devices; meaning that if your device only connects via a 2.4 GHz connection, the 5 GHz bands can be disabled for the IoT network, allowing your other devices to keep their high-speed connection from the main network.

Furthermore, if you would like to use the newest security protocols but are limited by your smart device's compatibility, the encryption method of the IoT network can be different from the method used on the main network to connect your devices.


How is TP-Link Embracing IoT Networks?


If you happened to catch the Wi-Fi 7 Product Launch Event, you might already know that a Private IoT network is featured in all of TP-Link’s current Wi-Fi 7 Lineup. For Wi-Fi 7 Routers supporting the feature, both the Deco BE95(2-Pack) and the BE900 are available for preorder now.


IoT Networking is already beginning to roll out to specific deco models, such as the Deco X50/55 (v1 and V1.6) and the new Deco XE200. If you do not see the feature available, please check that you are running the most up-to-date firmware from your model’s download page. If your device is not yet supported, keep an eye out for New Beta Firmware on the official TP-Link forums, and for new firmware updates on your model’s support page.

Will IoT network work when Deco is in AP mode? Will it be able to do VLAN tagging for devices connected to IoT network? 

Does the ioT network operate on a separate VLAN?

@Max_M @Karl_31 

Deco in AP mode also has an IOT network and it does not operate on a separate VLAN. It is untagged like the main network.

Thank you very much.

Best regards.

I am not sure to understand benefits of IOT network by TP-Link.

In fact, it looks like there are no security consideration, IOT network only allows to simplify configuration with I.E. the ability to disable 5GHz so it is "only" a second main network?

And how bandwitdh is not the same if all is in the same network but only with a different SSID?

Or is there something I did not understand?

I have a router with IOT network but I also have 3 RE305 repeaters connected via onemesh, how will IOT Network work now? My RE305 repeater does not have IOT network option. 

I wrote a long post here, but I lost it in the registration flow :(


Long story short, I do the same with my IoT devices: VLAN isolation + no internet access (restricted to a Home Assistant gateway in my case, but it could probably be an Apple TV or other commercial gateway). This is due to the abysmal security record of IoT devices (botnets, remote compromise and remote code execution, no security updates, etc).


Here, thanks to your answers, I can guess this just puts IoT devices on a separate IP range, hopefully with some firewalling on the AP side. It would be great to have more technical details on how the feature is implemented, I found this forum post by searching more information on the TP-Link BE900 "Private IoT Network" feature.


If I guessed right, the isolation is relatively minimal, and computers can reach the IoT devices if they try hard? (Self-assigning an IP on the same range). Though this could also be firewalled or not routed by the router. Again, I'd like to have more details, especially on the available knobs. Can we make an exception for a single device to be in both networks? Can we disable Internet access for that network? Etc.

My IoT device only connect through WPS. But connecting via WPS only get it into main network, not IoT network. Any workaround?

Is the iot network communicating with my home network or must I switch between the networks all the time?

They basically on the same network, just different SSID (and different frequency if you choose to)
