2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
HF-A11x module can be configured as both wireless STA and AP base on network type.
Logically there are two interfaces in HF-A11x. One is for STA, and another is for AP. When HF-
A11x works as AP, other STA equipments are able to connect to wireless LAN via HF-A11x
module. Wireless Networking with HF-A11x is very flexible.
Following figure shows the functional architecture of HF-A11x module:

Notes:
AP: that is the wireless Access Point, the founder of a wireless network and the centre of the
network nodes. The wireless router we use at home or in office may be an AP.
STA: short for Station, each terminal connects to a wireless network (such as laptops, PDA and
other networking devices) can be called with a STA device.

2.1.1. Basic Wireless Network Based On AP (Infrastructure)
Infrastructure: it’s also called basic network. It built by AP and many STAs which join in.
The characters of network of this type are that AP is the centre, and all communication between
STAs is transmitted through the AP. The figure following shows such type of networking.

2.1.2. Wireless Network Based On Adhoc Network (Adhoc)
Adhoc: It’s also called independent basic service set, and it’s built by two or more STAs without
