A WiFi module relates to the IoT transmission layer. It converts the TTL level or serial port into the embedded module. An array of IoT products rely on wireless connectivity. We have various wireless options, but all devices are not IP addressable which is an essential IoT feature. Moreover, the radio frequency design is characteristically tough. Few manufacturers have the skills for implementing antenna and RF design to keep the design updated with modern-day standards for FCC compliance. Designers have proven and very solid choice for IoT and wireless connectivity. We know this option as WiFi modules. In this article, we will discuss the features, specifications, and use cases of the ar9331 WiFi module.
We have various wire-free interface options. These include BLE (Bluetooth-Low-Energy), Z-Wave, RFID, WiFi, and ZigBee. All these interface options come with a unique combination of data rates, range, mesh networking, usage ease, interference immunity, and power.
However, a few interfaces are still not native-IP enabled. Therefore, it is not possible to address them directly or to exchange information or data with servers and other devices using the internet. Therefore, such situations require a new gateway that can add complexity and extra expense to the solution.
To deal with such situations, WiFi plays its role. It uses IEEE 802.11 standards having IP addressability. Therefore, we need WiFi modules, such as the ar9331 WiFi module. Today, almost all devices that communicate using the internet require a WiFi feature. Without it, we will not be able to perform many internet-based tasks in a precise manner.
As we already said, a WiFi module is a must for various IoT-based devices. Therefore, we can understand that its use cases would be almost endless. Some of the most common applications of WiFi modules include:
