Part 3 Product Review
3.1 Outline
This part is the introduction of WIFI module by the hardware and functions.
Interface is the standard UART（RS232/RS485/USB）for convenient to connect to user
device See the picture as follows:

Notes: now this device only have the function of serial port transparent data
transmission. The above product is USB interface, if you need is RS485 or RS232, we
will give you the corresponding interface as your requirement.
3.2 Antenna
This module has an IPX antenna interface.
WIFI module can use the following antennas which have passed the related
certifications:

3.3 Wireless network choosing
Wireless network includes Infra and Adhoc, our WIFI module can support both
of them.
There are two concepts we need to know:
AP, in computer networking, a wireless access point (AP) is a device that allows
wireless devices to connect to a wired network using Wi-Fi, or related standards. The
AP usually connects to a router (via a wired network) if it's a standalone device, or is
part of a router itself.
A station (STA) is a device that has the capability to use the 802.11 protocol. For
example, a station may be a laptop, a desktop PC, PDA, access point or Wi-Fi phone.
Infra Network：
Infra is created by AP, lots of STA access into it. AP is the network center, all
the communication is transfer by AP.
1. Can expand the communication range by wireless router
2. The IP address can be dynamically allocated by the router's DHCP function
3. Can set WPA2 encryption to protect the data safe in network
If you use Shuncom WIFI module, As long as the work area have wireless internet to
access, Shuncom WIFI module can access the Internet. In other any place, if you
can serve on the internet, you can control the Shuncom WIFI module by network.

Adhoc Network:
Adhoc is organized by at least two STA, not exist AP. It has the
following characteristics:
1. Not need router
2. Can support many modules to access
3. Need to set static IP
It is a low cost, easy-to-use mode, you can directly connect module by
laptop or mobile phone not depending on wireless router.
3.4 Security Mechanisms
This module supports multiple wireless encryption modes to make sure
the user data safe.
The encryption includes:
OPEN (no encryption)
WEP64
WEP128
WPA-PSK
WPA2-PSK
3.5 UART transparent transmission
This module is for the UART transparent data transmission. User
firstly needs to configure the following wireless network parameters
before communication:
Network name（Ssid）
Safety mode
Encryption (depends on your need to choose)
Defaulted TCP/UDP connection parameters:
Protocol type
Connection type
Destination address
Destination port
3.6 WIFI Configuration Tool
For convenient to use, we provide the simple configuration tool to configure. All
the parameters will be saved in the chip flash after configuration until there is a new
configuration.

3.7 AT command configuration
Besides WIFI configuration tool, you also can use the AT command to configure.
The details please see the back chart of AT command
3.8 TCP/IP Protocol
Shuncom WIFI module is embedded a complete TCP/IP protocol which supports
TCP/UDP/ICMP/ DHCP/DNS etc. protocols.
Part 4 How to use the WIFI module
4.1 Preparation
Hardware:
Shuncom WIFI module
Shuncom WIFI board

4.2 Web parameters configuration
If the laptop supports WIFI, or the mobile phone supports WIFI and ADHOC, you
can use the web to do configuration. If not, please see 4.3 to use Serial port tool to
configure.
If the first time power supply, module will create a point-to –point network by
using defaulted parameters. Defaulted SSID: SHUNCOM_hoc, Defaulted IP address:
169.254.1.1
After power supply, laptop begins to search the network, Point-to-point network
(SHUNCOM_hoc) will appear in the list of network:
