====== AH_NETBRIDGE_V2.1 Bridge ======

This page documents the **AH_NETBRIDGE_V2.1**, a HaLow (802.11ah) bridge device that integrates a HaLow module and provides Ethernet/network gateway functionality.  
It is ideal for connecting HaLow networks to standard IP networks and for use in multi‑hop or sensor gateway deployments.

===== Description =====
The AH_NETBRIDGE_V2.1 is a ready‑to‑use bridge product. Internally it houses a HaLow module and exposes Ethernet or network interface(s) to connect HaLow nodes to IP infrastructure. It supports AT command configuration via the underlying module.

===== Key Specifications & Features =====
  * HaLow frequency band: ~900 MHz (varies by region)  
  * Supports AP, STA, and Relay (AP+STA) modes  
  * Allows multi‑hop HaLow network bridging into Ethernet/IP domain  
  * Configurable via AT commands on the embedded module  
  * Can set channel list, bandwidth, TX power, sleep/wake modes  
  * Useful for IoT / sensor networks / long‑range links  
  * Bridge product provides a simpler interface than raw module, suitable for integration

===== Use Cases =====
  * Linking HaLow sensor/station nodes to an Ethernet/WiFi backbone  
  * Acting as a gateway in multi-hop HaLow relay networks  
  * Protocol translation between HaLow and TCP/IP systems  
  * Field deployment: HaLow long‑range link into data center or edge server  
  * Experimentation: Use as prototyping platform to evaluate HaLow module capabilities

===== Setup & Configuration Notes =====
  * Verify module firmware version and compatibility (refer to AT command reference)  
  * Connect to the device’s network interface or serial console to issue AT commands to the module  
  * Typical configuration sequence:  
    ```
    AT+CHAN_LIST=9080,9160,9240  
    AT+BSS_BW=8  
    AT+SSID=bridge_network  
    AT+ENCRYPT=1  
    AT+KEY=12345678  
    AT+WIFIMODE=ap  
    ```
    Then set up the Ethernet side and network routing as needed  
  * If deploying in regulated bands, set frequency range accordingly  
  * Confirm that the bridge firmware on the board allows access to the AT interface

===== Notes & Cautions =====
* Because the bridge hosts a HaLow module, the same restrictions and regional regulatory concerns apply (e.g., permitted frequency bands, TX power limits)  
* Access to full AT commands depends on vendor configuration  
* For advanced use (e.g., integrating with Linux hosts or custom software stacks), you may need to expose the module’s AT interface or install a driver on the host side

===== Summary =====
The AH_NETBRIDGE_V2.1 offers a convenient turnkey path into HaLow networking and bridging into IP systems. Thanks to its embedded HaLow module and AT‑command support, it allows both rapid deployment and deeper experimentation for RF/long‑range network work.
