If your internet speed is slow or your data plan is limited, it can be difficult to set the IOT (Internet of Things) device. Smart cameras, sensors, thermostats, and connected equipment rely on the Internet to communicate. But what if your network cannot handle heavy data load? The good news is – IOT does not always require high bandwidth. With the right setup and protocol, you can easily run IOT devices on limited internet as well.
Understanding IOT and Internet bandwidth
Your IOT device communicates by sending small packets of data – temperature updates, location details, motion alerts, etc., but some devices (such as camera or smart speakers) send large amounts of data such as videos or audio. Bandwidth means how much data can move through your internet connection at a certain time. If the bandwidth is very low, the devices can update, disconnect or fail to update.
How much bandwidth is the use of IOT devices?
IOT devices vary widely in data usage:
- Smart sensor (temperature, humidity, speed): ~ 50 kbps to 250 kbps
- Smart Lights & Plug: ~ 50 kBPS
- Smart Speaker (Alexa, Google Home): ~ 500 KBPS to 1.5 Mbps
- IP Security Cameras: 1-5 Mbps (depending on video quality)
- Wearables: ~ 100 kbps
If you are running several devices on a limited plan, you need to choose a low-detta option and control how many times they send updates.
Why limited bandwidth is a challenge for IOT
Less bandwidth may be:
- Slow response time
- Connection dropped
- Missed alert or delayed notifications
- Unsuccessful firmware update
- Drain due to recurrence of high battery efforts
Fortunately, using low-power IOT protocols and smart configurations can solve many of these issues.
Choosing the right IOT communication protocol
Protocols determine how your IOT device talks on the Internet. Some are light and are made for low-bandwidth environment, while others are better for high-speed networks. Choosing the right protocol when the bandwidth is limited can make or break your IOT setup.
Which IOT communication protocol is designed for low power equipment with limited network bandwidth?
Many protocols are designed for this accurate requirement:
- MQT-SN (Message queuing telemetry transport for sensor network): light and perfect for low-power sensors.
- COAP (constrained application protocol): runs on UDP, making it bandwidth-friendly.
- Lorawan (Long Range Wide Area Network): extremely low data usage, long distance coverage.
- NB-IOT (narrow IOT): Cellular-based, designed for low data and broad coverage.
If your devices walk on the battery and need small data, Loravan and NB-IOT are excellent options.
What are the four types of IOT network?
IOT network can be classified into four main types:
- PAN (individual field network): small range, Bluetooth -like devices.
- LAN (local area network): Wi-Fi network inside homes or offices.
- WAN (Wide Area Network): Cellular network covering large areas.
- LPWan (low power wide area network): Lorwan, NB-IOT is designed for a distance and less bandwidth.
What is the bandwidth of narrow IOT (NB-IT)?
The NB-iOT is operated with data rates up to a maximum bandwidth of approximately 200 kHz and up to 250 kbps. Although it is not sharp, it is perfect for devices that only need to send data in small amounts such as smart meters or environmental sensors.
Which protocol is more suitable for low bandwidth applications?
If your internet speed is limited, consider:
- MQT: Lightweight, reliable, great for small messages.
- Coap: Minimum overhead, ideal for constrained equipment.
- Loravan: Use of extremely low bandwidth, long distance.
- NB-IOT: Low speed but works well on cellular network.
For most home IOT setup, MQTT or Coap would be the best option.
What are the four main protocols of IOT?
The most commonly used IOT protocols:
- MQTT
- COAP
- Amqp
- Http/https (hypertext transfer protocol)
Each has professionals and opposition – MQTT and Coap are the best for low bandwidth, while HTTP is heavy but widely supported.
Adaptation of IOT devices for limited bandwidth
Here are some practical suggestions:
- Adjust the reporting interval: send the data less frequent (eg, every 10 minutes instead of every minute).
- Use data compression: Many IOT devices allow it.
- Disable unnecessary features: when not needed like live videos.
- Schedules updated during off-pick hours: Avoid busy time.
- Use a local gateway: Collect data locally and send it to the batches.
Using Gateway and Edge Computing
A gateway can collect and process the IOT data locally before sending to the cloud. Edge reduces computing how much data travels on the Internet by analyzing it near the device. It can save a large amount of bandwidth and give speed to the response time.
Managing firmware updates with slow internet
Firmware update can eat bandwidth. Management:
- Schedule updated at night or off-pak.
- Use delta updates (only changes are sent).
- Download updates on a gateway and locally push them to all devices.
Security idea on low bandwidth network
Even with limited bandwidth, do not leave security:
- Use light encryption like DTLS for coap or TLS for MQTT.
- Keep the firmware updated, but schedule smartly.
- Monitor the abnormal device traffic (suddenly spikes can do signal hacking).
conclusion
You do not need super-fast internet connection to create a reliable IOT setup. By selecting a low-bandwidth protocol like MQT, Coap, Lorawan, or NB-IT, adaptation of data uses, and using gateway or age computing, your devices can also work efficiently with limited internet. The plan update wisely, secure your network, and your IOT system will run smoothly without eating your bandwidth.
