### **Cons of the Arcadyan WN7522C-1-LF-19**

1. **Limited to 2.4 GHz Band**

The module does **not support the 5 GHz band**, which can be a drawback in environments with heavy congestion on 2.4 GHz (e.g., smart homes, offices). This may lead to **lower speeds and instability** in crowded networks.

2. **Outdated Chipset**

- **Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) support**, which offer higher speeds and better efficiency.

- **Better security protocols** (e.g., WPA3, improved encryption).

- **Modern power-saving features** (e.g., target wake time in Wi-Fi 6).

This could limit its use in future-proof applications.

3. **No Built-in Antenna Options**

The module typically requires an **external antenna** (often sold separately), which adds to the cost and complexity of integration. Some variants may include a **PCB-mounted antenna**, but performance may be suboptimal compared to external antennas.

4. **Limited Range in Dense Environments**

Due to its **2.4 GHz-only** operation and lack of advanced beamforming, the module may struggle in **large or obstacle-rich environments**, where signal strength degrades quickly.

5. **Dependence on Host System for Processing**

The module itself is a **wireless transceiver** and does not include a full CPU. Heavy processing (e.g., encryption, protocol handling) is offloaded to the host microcontroller or SoC, which may require additional resources.

6. **Potential Driver and Firmware Limitations**

While Arcadyan provides drivers, some users report **compatibility issues** with newer operating systems or custom firmware. This may require additional development effort to ensure smooth operation.

7. **No Bluetooth or Other Wireless Protocols**
