Fully managed cloud service for a wireless IoT gateway design

Article By : Majeed Ahmad

A new IoT gateway design is the latest manifestation of fully managed cloud connectivity for rapid evaluation, prototyping, and applications development.

Fully-managed cloud services enable rapid evaluation, prototyping, and development of the Internet of Things (IoT) connectivity applications, and the COT Smart IoT Gateway developed by Cloud of Things is the latest manifestation of this design evolution. The IoT gateway solution securely collects sensor and equipment data from the edge of the network for localized or cloud-based analysis and it’s targeted at applications such as home monitoring and security, lighting, and smart appliances.

Cloud of Things is demonstrating this fully-managed IoT gateway solution at the ICS West trade show being held in Las Vegas on 19-21 July 2021. The IoT gateway is based on the company’s DeviceTone technology that simplifies the connectivity design for cloud-centric applications (Figure 1).

The wireless interface in the COT Smart IoT Gateway design is built around the fully-certified DHAN-M ULE module that employs the embedded OpenWRT OS (Figure 2). The module features a secure U-Boot bootloader, fail-safe firmware over-the-air (FOTA), two Ethernet ports and Wi-Fi connectivity, all in a box measuring 82 x 82 x 30 mm and weighing 220 g.

Besides rapidly closing time-to-market windows, sensor-to-hub communication is increasingly challenged by noisy RF environment. Here, solutions like the ULE module simplify the wireless interface for the IoT gateway design.

It’s worth mentioning here that DSP Group has been working with cloud service providers like AWS, Baidu, and Google to port their algorithms on its silicon. That, along with a suite of cloud services from Cloud of Things, further bolsters the process of making designs like IoT gateways cloud-ready.
