Through device connectivity and intelligent communication across several systems, the Internet of Things (IoT) is revolutionizing businesses. The network, which serves as the conduit for data transfer between linked devices, is the foundation of any Internet of Things system.
The types of IoT networks, important IoT network protocols, their applications, and how to select the best network for your IoT application will all be covered in this article.
What is an IoT Network?
Interconnected physical devices with sensors, software, and other technologies installed that allow data exchange and communication make up an Internet of Things network. Frequently without human assistance, the network guarantees smooth connectivity between systems, devices, and IoT platforms.
Some factors must be taken into account while selecting the best IoT network:
- Area of Coverage
- Consumption of Power
- Device Density
- Quantity and Type of Data Expenses
- Environment for Security and Use Case
To assist you in choosing the best choice for your IoT project, let's take a closer look at the various kinds of IoT networks and their distinctive features.
Types of IoT Networks
Wireless IoT networks come in a variety of forms, each tailored to meet specific needs and use cases. Let's dissect the most popular IoT networks:
1. Cellular Networks: LTE-M vs. NB-IoT
Applications for the Internet of Things that need long-distance communication frequently employ cellular networks. LTE-M (Long-Term Evolution for Machines) and NB-IoT (Narrowband IoT) are the two most widely used IoT cellular technologies.
LTE-M (Cat-M1)
- Use cases: Include home security, wearable technology, medical equipment, point-of-sale systems, and asset tracking.
- Advantages: High-density connections are supported, along with increased bandwidth and mobility and voice-over IP (VoIP) capabilities.
- Power Consumption: Designed for low-power applications, yet more power-intensive than NB-IoT.
NB-IoT
- Use Cases: Fleet management, asset management, smart cities, connected farming, and smart metering.
- Strengths: Cost-effectiveness, improved interior and underground coverage, and reduced power use.
- Power Consumption: Its extremely low power consumption makes it perfect for gadgets that need longer battery life.
2. LAN/PAN: WiFi vs. BLE
For short-range Internet of Things applications, Local Area Networks (LAN) and Personal Area Networks (PAN) are perfect. Bluetooth Low Energy (BLE) and WiFi are two of the most widely utilized technologies.
WiFi
- Use cases: WiFi includes medical equipment, smart building systems, security cameras, and smart homes.
- Strengths: A wide coverage area inside a small network and fast data transfer.
- Weakness: Due to its high power consumption, it is not appropriate for extensive IoT deployments involving battery-powered devices.
Bluetooth Low Energy (BLE)
- Use cases: Fitness trackers, smart home appliances, and retail applications (such as beacon-based proximity marketing) are some examples of Bluetooth Low Energy (BLE).
- Strengths: It is ideal for short-range applications due to its extremely cheap cost and power consumption.
- Weakness: Lower data throughput and a smaller data range than WiFi.
3. LPWAN (Low Power Wide Area Networks)
A common IoT network option for applications needing low-power, long-range connectivity is LPWAN. Sigfox and LoRaWAN are two of the most popular LPWAN technologies.
LoRaWAN
- Use cases: LoRaWAN includes environmental monitoring, remote asset tracking, smart cities, and smart lighting.
- Strengths: Low power consumption, scalability for large deployments, and long-range communication (up to 15 km).
- Weakness: Its limited data throughput makes it appropriate for applications that send little data packets.
Sigfox
- Use Case: Asset management, remote monitoring, and smart buildings.
- Strengths: Great range (up to 50 km in rural regions) and extremely low power usage.
- Weakness: Dependency on a third-party network provider and low data transfer rate.
4. Mesh Protocols
For medium-range applications where devices communicate over a dispersed network, mesh networks operate incredibly well. Thread and Zigbee are the two most often used mesh protocols.
Zigbee
- Use cases: Zigbee includes security systems, smart meters, lighting control, and home automation.
- Strengths: Strong security features, scalable, dependable, and low power consumption. Zigbee networks are perfect for smart cities and buildings since they can accommodate a lot of devices.
- Weakness: Relatively narrow range and low data throughput when compared to other IoT networks.
Thread
- Use cases: The thread includes connected appliances, environmental monitoring, and smart home systems.
- Strengths: Mesh networking is supported for device-to-device communication, and it is dependable and low-power.
- Weakness: Only works with devices that have the infrastructure and support for Thread.
How to Choose the Right IoT Network?
Several important aspects influence the choice of IoT network:
- Power Consumption: Select low-power networks such as BLE, NB-IoT, or LPWAN for Internet of Things devices that run on batteries.
- Coverage Area: Take into account cellular networks (LTE-M, NB-IoT) or LPWAN (LoRaWAN, Sigfox) for long-distance communication.
- Requirements for Data: BLE and LoRaWAN are preferable for low-data applications, but WiFi is the best option if your IoT application requires significant data throughput.
- Device Density: Mesh networks such as Thread or Zigbee can offer reliable and scalable solutions for devices that are closely spaced.
- Cost: For extensive IoT deployments, low-power networks like NB-IoT and BLE are typically more affordable.
