AP, this type of network is a loose structure, all the STAs in the network can communicate 
directly.  
 
As showing in the figure below, HF-A11x (1) can be treat as an AP, and HF-A11x (2), HF-A11x (3) 
and the laptop are STAs connected to HF-A11x (1). Meanwhile, all HF-A11x modules can 
connected to user device via UART interface. All HF-A11x modules can be operated and 
managed through the laptop. So it is convenient to O&M all HF-A11x modules. Moreover, in such 
Adhoc network structure, the whole coverage of a wireless network can be extended easily.  
 

 

Figure 17.  HF-A11x Adhoc Network Structure 

HF-A11x module supports multiple wireless encryption mechanisms, and enables to protect the 
security of user’s data transmission, the mechanisms include: 

 

‹ WEP 
‹ WAP-PSK/TKIP 
‹ WAP-PSK/AES 
‹ WAP2-PSK/TKIP 
‹ WPA2-PSK/AES 

HF-A11x support Multi-SSID when works at STA mode. Module can set maximum 3 AP’s SSID. 
After modoule boot-up, it will auto search 1st SSID and try to connect with this AP. If 1st SSID 
can’t link, it will search 2nd SSID, and then 3

rd

 SSID, until successful connected with one AP.  

 
Module will query link status every 5 second when try to connect to dedicate AP. For each SSID, 
user can set different encryption method.If this function is open, user can set different SSID 
through web page, “STA Interface Setting Page”.
