### **Cons**

1. **Outdated Wi-Fi Standard (Wi-Fi 4)**

The module uses **802.11n (Wi-Fi 4)**, which is now several generations old. While it works well for basic IoT and embedded applications, it lacks the **higher speeds, better range, and improved efficiency** of newer standards like **Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax)**. This may become a limitation in the future as networks upgrade.

2. **Limited Range Compared to Modern Modules**

Wi-Fi 4 has **lower range efficiency** than newer standards, especially in dense environments. If your application requires **long-range connectivity**, you may need additional solutions like repeaters or mesh networking.

3. **No Built-In Bluetooth or Dual-Mode Support**

Unlike newer modules (e.g., ESP32 or some Wi-Fi 6 chips), the AZ832-HN **does not support Bluetooth or dual-mode (Wi-Fi Bluetooth)**. If your project requires both wireless technologies, you would need a separate module.

4. **No Support for Advanced Features**

- **MU-MIMO (Multi-User Multiple Input Multiple Output)** Not useful for single-device applications.

- **OFDMA (Orthogonal Frequency-Division Multiple Access)** Not applicable here.

- **Beamforming** Not present, which could slightly reduce range efficiency.

- **Wi-Fi 6 enhancements** (like 1024-QAM, 160 MHz channels).

5. **Limited Antenna Options**

The module typically comes with a **single antenna**, and while external antennas can be connected, the design may not support **MIMO configurations** (which require multiple antennas). This restricts performance in multi-path environments.

6. **Potential Firmware Limitations**

While the module supports AT commands, some advanced features (e.g., **custom firmware flashing, deep packet inspection, or advanced security tweaks**) may require reverse-engineering or third-party tools, which can be complex.

7. **No Official Linux Driver Support**

Unlike some modules that have **open-source drivers**, the AZ832-HN primarily relies on **proprietary firmware**. This can be a drawback if you need **Linux-based embedded systems** with full driver control.

8. **Slightly Higher Latency in Some Cases**

Older Wi-Fi standards can have **higher latency** compared to Wi-Fi 5/6, which may be noticeable in real-time applications like voice or video streaming.
