FUNCTIONAL DESCRIPTION
2.1.
Wireless Networking
HF-LPT120 module can be configured as both wireless STA and AP base on network type. Logically
there are two interfaces in HF-LPT120. One is for STA, and another is for AP. When HF-LPT120
works as AP, other STA equipments are able to connect to HF-LPT120 module directly. Wireless
Networking with HF-LPT120 is very flexible.
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.
