2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
The CH232BGN module can be configured to operate as either a WiFi Station (STA) or Access Point
(AP). Internally the CH232BGN incorporates separate interfaces for a WiFi Station or Access Point.
When the CH232BGN works as an Access Point, other Stations are able to connect to the wireless
LAN via the CH232BGN module. Figure 10 below shows the functional architecture of the CH232BGN
module:

Notes: An Access Point serves as a router providing WiFi services to a network of wireless nodes.
A Station serves as a wireless node to an established network
.
2.1.1. Basic WiFi Network Architecture
A basic WiFi network features an Access Point at its hub supporting multiple Stations. All
communications between Stations pass through the Access Point. Figure 11 below shows an
example of a basic WiFi network
