Project Summary:

The IOT gateway designed by Qmax is based on the Qualcomm QCA4531 + QCA 4024 chipsets. It has Wi-Fi, BLE 5.0, ZigBee and Thread. It connects to Internet using Wi-Fi or Ethernet. The gateway connects to other devices through BLE or ZigBee. This way, the Gateway acts as a bridge between the IOT devices on side and the Internet on the other.The QCA4531 has inbuilt Ethernet and PCIe features. We can add other functionality to the gateway through the PCIe slot available on board. The device is powered by an external Power Adapter. The QCA4531 is a low-cost turnkey solution that brings high-performance connectivity capabilities in a user programmable Linux/ OpenWRT environment. OpenWRT offers a built-in package manager that allows packages to be installed directly from a software repository, greatly simplifying development. Benefiting from the extended range based on 2x2 11n, it is designed to serve as a feature-rich IoE node and as a hub to bridge between multiple protocols and ecosystems. The QCA4531 can function as an Access Point supporting up to 16 simultaneous devices and is also power-optimized to enable appliances to meet international standards for energy efficiency. It supports the AllJoyn connectivity software framework and services, allowing devices to discover, connect and communicate directly with one another. The QCA4024 SoC is a multi-mode system-on-chip with support for Bluetooth 5 and 802.15.4-based technologies, including Zigbee and Thread. This low power SOC integrates a Cortex M4F for application processing and a Cortex M0 for network stack processing designed to enable a highly concurrent multiple radio solution. The QCA4020 SDK from Qualcomm Technologies pre-integrates support for advanced security features and mesh networking. This solution complements portions of the portfolio beyond IoT devices to address multiple industries.
