Hz. However, the trade-off is that 2.4 GHz has slower data transfer speeds compared to 5 GHz. This is because 2.4 GHz is more crowded with other devices and can experience more interference, which affects its speed.
When it comes to IoT devices, the choice between 2.4 GHz and 5 GHz depends on the specific requirements of the device and its intended use. Here are some key points to consider:
1. Range: 2.4 GHz has a longer range compared to 5 GHz, making it more suitable for devices located far away from the Wi-Fi router.
2. Penetration: 2.4 GHz signals can penetrate walls and obstacles better than 5 GHz signals, making it ideal for devices placed in different rooms or separated by walls.
3. Speed: 5 GHz offers faster data transfer speeds than 2.4 GHz, making it better for high-bandwidth activities like gaming and streaming.
4. Interference: 2.4 GHz is more susceptible to interference from other devices like microwaves, cordless phones, and baby monitors, which can affect its performance.
5. Device Compatibility: While most smart devices support both 2.4 GHz and 5 GHz, some older or less expensive devices may only support 2.4 GHz.
6. Band Steering: Some Wi-Fi routers have a feature called band steering that automatically assigns devices to the appropriate band based on their capabilities and network conditions.
7. Mesh Systems: If you’re using a mesh Wi-Fi system, it may handle the band selection automatically to optimize performance and coverage.
8. IoT Communication Standards: Certain IoT protocols, such as Zigbee or Z-Wave, use separate frequencies and don’t rely on Wi-Fi bands.
9. Congestion: In crowded areas with many Wi-Fi networks, 2.4 GHz may suffer from more congestion and interference, affecting its performance.
10. Future Proofing: While 2.4 GHz is more widely supported and compatible with older devices, 5 GHz offers better speeds and is becoming more prevalent in newer devices.
Based on these considerations, it’s important to evaluate the specific requirements of your IoT devices and the network conditions in your environment to determine whether to use 2.4 GHz or 5 GHz.
Now let’s move on to some frequently asked questions about IoT and Wi-Fi bands:

Yes, most modern routers support both 2.4 GHz and 5 GHz bands and allow you to set up a dual-band network. This way, you can connect devices that support either band and maximize the benefits of each frequency.
8. What should I do if my IoT devices don’t connect to the desired Wi-Fi band?
If your IoT devices automatically connect to the “wrong” Wi-Fi band, you can try disabling the band steering feature on your router, if applicable. You can also create separate network names (SSIDs) for each band and manually connect your devices to the desired one.
9. How can I improve the Wi-Fi signal for my IoT devices?
To improve Wi-Fi signal for your IoT devices, you can try relocating your router to a more central location, reducing interference from other devices, using Wi-Fi extenders or mesh systems, or upgrading to a more powerful router.
10. Will the choice between 2.4 GHz and 5 GHz become obsolete with the advent of 5G?
The choice between 2.4 GHz and 5 GHz will still be relevant even with the advent of 5G. 5G primarily refers to cellular networks, while 2.4 GHz and 5 GHz are Wi-Fi bands. IoT devices that connect to Wi-Fi will still be primarily using these two bands, depending on their specific needs and the capabilities of their Wi-Fi routers.
Should IoT be 2.4 GHz or 5GHz
Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV.

Why do smart devices use 2.4 GHz
The 2.4 GHz band has better range than its 5GHz counterpart and can penetrate through walls/ceilings or any sort of obstacles better than the 5Ghz band. Since Smart home devices such as smart bulbs and smart cameras are usually mounted outdoors or on walls and ceilings, it makes sense to go with the 2.4Ghz band.
Why is 2.4 GHz better than 5GHz
The primary differences between wireless frequencies are the range (coverage) and bandwidth (speed) that the bands provide. The 2.4 GHz band provides the most coverage but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds.
