IoT gateway devices vs. IoT devices: A detailed comparison for OEMs

When designing and implementing IoT solutions, aim to select the appropriate hardware components that will form the foundation of your IoT ecosystem. Two crucial elements in this decision-making process are the IoT gateway device and the IoT device itself.

Understanding the distinctions between these two is essential to making informed choices that align with your specific application requirements. Here is how they compare:

IoT network considerations for OEMs

IoT products rely heavily on networks to establish communication channels with gateways, sensors, servers, routers, and other IoT devices. This communication involves transmitting and receiving data, enabling them to carry out their intended functions.

Although there are a wide range of choices regarding network connectivity options, not all are created equal. Some are not specifically designed for IoT and have limited use cases. On the other hand, some are purpose-built to cater to specific types of IoT applications.

The following section explores the factors that should be considered when evaluating IoT network connectivity for your IoT ecosystem, along with an overview of the most popular options available:

1. WiFi

WiFi uses radio waves to transmit data between devices and a wireless router or access point:

• It is suitable for IoT applications that involve the transfer of large amounts of data. This includes applications like video streaming, real-time monitoring, and high-resolution sensor data collection, where a fast and reliable wireless connection is necessary.
• WiFi can leverage existing internet infrastructure, such as routers and access points, making it easier to integrate IoT devices into an already established WiFi network.

The only con is that WiFi can consume more power compared to other connectivity options, which may not be suitable for battery-powered devices. The range can be limited, especially in environments with obstacles or interference. Setting up and managing WiFi networks may also require technical expertise.

2. Bluetooth

Bluetooth is well-suited for short-range communication within limited physical proximity. It allows IoT devices to connect and exchange data wirelessly over distances typically up to 100 meters, depending on the Bluetooth version and power levels.

• It has broad device compatibility, with most modern smartphones, tablets, laptops, and IoT devices equipped with Bluetooth capabilities. This compatibility makes it easier to connect and communicate between different devices in an IoT ecosystem.
• It supports encryption, authentication, and authorization mechanisms to protect data privacy and prevent unauthorized access.
• Protocols, such as the Generic Attribute Profile (GATT) for BLE and the Universal Asynchronous Receiver-Transmitter (UART), provide standardized frameworks for building IoT applications on top of Bluetooth. For instance:
• GATT is well-suited for IoT applications that involve exchanging sensor data between devices. IoT devices equipped with sensors, such as temperature, humidity, or motion sensors, can use GATT to transmit this data to a central device or server for processing and analysis.
• UART is often used when real-time data transfer is crucial. IoT applications that require real-time monitoring or control, such as robotics or automation systems, can benefit from the reliable and immediate data transfer offered by UART.

However, Bluetooth has a limited range compared to other wireless technologies, typically around 10 meters. It may not be suitable for devices that require long-range communication. The data transfer rate is also lower compared to WiFi, which can be disrupted by physical obstacles.

3. Zigbee

Zigbee is used in solutions where a large number of low-power IoT devices need to communicate with a central hub or gateway, such as home automation, smart lighting, and industrial monitoring systems.

• It can be used to build energy management systems that monitor and control energy consumption in buildings. It enables the integration of smart meters, thermostats, and other energy-related devices, enabling efficient energy usage and demand response.
• By using Zigbee tags or beacons, objects or assets can be easily tracked within a specific area, such as a warehouse or logistics facility, because of its mesh topology.

The only disadvantage is that Zigbee has a shorter range than WiFi or cellular networks, typically around 10–100 meters, and it may require a Zigbee coordinator or gateway for connecting to the internet.

4. LoRaWAN

Long-Range Wide Area Network, or LoRaWAN, is used in applications such as smart agriculture, asset tracking, and smart city apps.

• It offers excellent range capabilities, allowing devices to communicate over several kilometers in outdoor environments. If your IoT deployment requires long-range connectivity, especially in rural or remote areas, LoRaWAN can be a suitable choice.
• It is designed to operate on low power, making it ideal for battery-powered or energy-constrained IoT devices.
• Deploying a LoRaWAN network infrastructure is generally more cost-effective compared to cellular networks or other LPWAN technologies as it requires fewer gateways and operates in unlicensed frequency bands.

However, LoRaWAN has lower data transfer rates than WiFi or cellular networks, typically a few kilobits per second. It requires the deployment of LoRaWAN gateways to create network coverage, which may involve higher upfront costs.

5. Cellular networks

Cellular networks (e.g., 2G, 3G, 4G, or 5G) are commonly used in asset tracking, fleet management, and remote monitoring applications.

• They are designed to handle large-scale deployments, making them suitable for IoT applications that involve a high number of devices.
• They offer a robust infrastructure capable of supporting thousands or even millions of connected devices simultaneously.
• Cellular networks often incorporate strong security measures, including encryption protocols, to protect data transmitted between IoT devices and backend systems. This is essential for IoT apps, where data privacy and integrity are critical concerns.

However, this option consumes more power than other low-power wireless technologies, which may not be suitable for battery-powered IoT devices with long operational lifetimes.

Subscription costs for cellular connectivity can add to the overall expenses. In remote or rural areas, network coverage may be limited.

Protocols for connecting the device to the cloud:

6. MQTT

Message Queuing Telemetry Transport, or MQTT, is lightweight and efficient, making it suitable for resource-constrained devices and low-bandwidth networks.

• This model is well-suited for scenarios where multiple devices need to exchange information without direct point-to-point communication. It allows for decoupling and scalability in IoT systems.
• Many IoT devices operate on limited power sources, such as batteries. MQTT's lightweight nature and efficient data transfer help conserve power, making it a good choice for energy-constrained devices.

The only con is that MQTT relies on a centralized broker, which introduces a single point of failure. The broker must be highly available and scalable to handle many connected devices.

Plus, the protocol does not provide built-in security mechanisms and requires additional measures such as Transport Layer Security (TLS) for secure communication.

7. AMQP

Advanced Message Queuing Protocol, or AMQP, is used in scenarios where message durability, transactional support, and complex routing scenarios are necessary.

• AMQP supports multiple messaging patterns, including point-to-point, publish-subscribe, request-reply, and more. This versatility allows you to choose the appropriate pattern based on the communication requirements of your IoT application.
• It supports a wide range of programming languages, platforms, and messaging brokers, making it easier to integrate with existing IoT systems and devices.

The only thing is AMQP may introduce additional complexity compared to lightweight protocols like MQTT. It requires more computational resources and bandwidth compared to MQTT. Implementing AMQP infrastructure may also involve higher upfront costs.

8. HTTP

Hypertext Transfer Protocol, or HTTP, is suitable for IoT applications that require direct communication between devices and cloud services using standard web protocols.

• It follows a request-response model, where a client sends a request to a server, and the server responds with the requested data. This model is suitable where IoT devices need to interact with web services or retrieve information from remote servers.
• HTTP includes built-in support for caching and proxy servers. Caching can be beneficial in IoT scenarios where data is frequently accessed or where devices have limited bandwidth. Proxy servers can help offload processing, caching, and load balancing.

Disadvantages? HTTP is not the most efficient choice for resource-constrained IoT devices due to its overhead and verbosity. For devices with limited processing power or bandwidth constraints, lightweight protocols like MQTT or CoAP may be more suitable

Key considerations for comparing IoT network connectivity solutions

• Coverage: Different connectivity technologies have varying coverage areas, ranging from local networks with limited range to wide-area networks that provide broader coverage. Assessing coverage ensures that your IoT products can establish a reliable connection in the intended deployment locations.
• Bandwidth: Consider your devices’ data-intensive tasks and ensure that the chosen connectivity solution can accommodate the required bandwidth. For instance, cellular networks are apt for apps that involve large data transfers, and LPWAN is more suitable for transmitting smaller amounts of data intermittently.
• Power consumption: As IoT devices rely on limited battery power, determine the amount of power they will consume while transmitting or receiving data over the chosen connectivity solution. Low-power connectivity options like LPWANs or BLE can operate for extended periods without frequent battery replacements.

• Cost: There are cost implications for the chosen connectivity solution. Check if you must establish and maintain your infrastructure, such as base stations or gateways. Additionally, list the necessary components and estimate any subscription fees or data usage charges associated with the connectivity solution.
• Security: Ascertain whether the chosen network type enhances or diminishes the protection against unauthorized access and misuse of your IoT devices and data. Look for connectivity solutions that offer robust security measures, such as encryption, authentication, and secure protocols, to avoid potential threats.
• Mobility: Check if the chosen connectivity can effectively maintain the connection and provide seamless communication while the devices move. This is crucial for applications such as asset tracking, vehicle telematics, or wearables that want connectivity on the go.

AWS IoT, for example, provides detailed documentation on IoT device provisioning and certificate management. By leveraging the capabilities offered by the IoT cloud platform, you can ensure secure authentication and establish trusted connections between your IoT devices and the cloud.

Authentication methods for cloud connections in an IoT ecosystem

Select one of the following approaches (AWS and Azure) based on hardware and firmware support, business rules, and feasibility:

A. Azure authentication methods

• Symmetric keys (shared access keys): This method uses a shared secret (password) to authenticate the device with the Azure IoT Hub. No certificate is required, and the device connects using a connection string or a Shared Access Signature (SAS) token password.
• X.509 self-signed certificates: This method involves using self-signed X.509 certificates to authenticate devices with the Azure IoT Hub. Each device has its own certification, and the Azure IoT Hub verifies its identity based on the certificate.
• X.509 Certificate Authority (CA)-signed certificates: This method utilizes certificates signed by a trusted CA to authenticate devices with the Azure IoT Hub. The certificates are issued by a trusted CA and verified by the Azure IoT Hub during authentication.

B. AWS authentication methods

• JITP (Just-in-Time Provisioning): JITP is an AWS IoT feature that provides devices with unique X.509 certificates during the first connection. AWS IoT Core generates and registers the certificates when a device connects for the first time.
• JITR (Just-in-Time Registration): JITR allows devices to be registered and provisioned in real-time upon initial connection. This method is primarily used when devices have pre-existing certificates issued by a trusted CA.
• Fleet provisioning: AWS IoT Core offers a customizable fleet provisioning template, a JSON document defining the provisioning workflow. This includes essential information like provisioning roles, policies, and certificates needed for devices. During provisioning, devices gain temporary service access via a bootstrap certificate. This feature is particularly valuable for large-scale device provisioning, enabling process automation and consistent security across all devices.

• Determine the expected device count to calculate the associated costs accurately.

2. Frequency of data communication

• Define the frequency of data communication from D2C and C2D interactions. The more frequent the communication, the higher the potential costs.
• Consider your application’s requirements and balance real-time responsiveness and cost efficiency.

3. Data payload size

• Predefine the size of the data payload transmitted between devices and the cloud. Cloud providers often have minimum payload sizes that count as a single event for costing purposes.
• If your data payload exceeds the minimum size, there may be multiple events and incur higher costs.

For example, the device’s data payload size is 10KB, and the cloud’s minimum size for a single data payload is 8KB (counted as one event for costing). Sending a single message with a 10KB payload would count as two events, resulting in higher costs.

4. Required services for business use case

Determine the cost of additional services required to achieve your business use case within the IoT cloud platform. These services may include:

• Cold data storage: Assess the costs of storing infrequently accessed or archival data. Cloud providers often offer separate pricing models for cold storage to optimize costs.
