What is an IoT Gateway?

Building automation systems are usually comprised of a mix of disparate systems added at different points in time. The key to having all these differing systems and protocols communicate with one another is the integration of a gateway to handle the communication layer between devices and from device to cloud.

Building automation systems are usually comprised of a mix of disparate systems added at different points in time. The key to having all these differing systems and protocols communicate with one another is the integration of a gateway to handle the communication layer between devices and from device to cloud.

When it comes to the Internet of Things, a gateway is a vital part of the architecture. In addition to handling local processing and storage, an IoT gateway translates protocols, processes and manages/filters data.

Using a gateway allows for a variety of different protocols to be implemented easily in a project. All of the different devices and sensors can use an array of protocols such as Wi-Fi, Bluetooth and Zigbee. Learn more about protocols in this blog post. 

The IoT gateway device bridges the gap between operations and IT infrastructure. According to GlobalSign and Leverege, here are some of the key benefits of a gateway:

  • High Scalability - In terms of scalability, a gateway makes it easier to add more sensors and devices to the system.
  • Lower Costs - IoT gateways allow for devices to have lower processing power. This helps to lover the cost of the devices, passing the savings on to the end user.
  • Expedited Production - With the higher processing power at the gateway, IoT solutions are produced faster and can go to market sooner.
  • Reduced Telecommunication Costs - Using less processing power also means using a smaller network, resulting in reduced telecommunication costs.
  • Mitigated Risk - The use of a gateway isolates devices and sensors and prevent them from causing problems before they occur.   
  • Increased Battery Life for Sensors and Devices - With the large amount of sensors and devices used in IoT, making sure all of the equipment is up and functioning is critical. Since these devices and sensors can connect in a very short range to the gateway, power consumption is greatly saved. This can cause a battery to last years instead of weeks or months.

In summary, without a gateway, the IoT ecosystem would not be able to communicate from the device to the cloud. A gateway is a key component of any smart building project as it provides a very important connection and helps bring all types of devices from many protocols together.

Making EV Charger Acquisition Affordable

In a previous blog post, we covered the basics of commercial Electric Vehicle (EV) chargers. With multiple options to choose from, there is a deeper discussion to be had around which charger type is the best fit for your facility and business type. Things like average dwell time and local driving demographics will certainly factor in your decision-making process, but the single most important aspect for all prospective buyers is cost.
