APPLICATION
2.1.
Wireless Networking
The device can be configured as both wireless STA and AP base on network type. Logically there
are two interfaces in the device. One is for STA, and another is for AP. When the device works as
AP, other STA equipments are able to connect to wireless LAN via the device. Wireless
Networking is very flexible.
Following figure shows the functional architecture:

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.
AP Application
Infrastructure: i
t‟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.
