2. Installation 2.1 Fundamentals of wireless LAN CMAX Module supports IEEE802.11b/g/n. This module support 11/54/72Mbps transmission rate respectively. There are two types of wireless LAN networks – infrastructure and ad-hoc. [Figure 2.1.1] Reference Network Architecture 2.1.1 Infrastructure Mode The wireless LAN stations communicate through an Access Point (AP). So, at least one AP is needed to make the infrastructure network.
[Figure 2.1.1.1] Infrastructure 2.1.2 Ad-hoc Mode Wireless stations communicate each other without the AP. So user can make a system more simply. It is proper if there’s no wired LAN requirement and it is a small network. Some people call it peer-to-peer mode. [Figure 2.1.2.1] Ad-Hoc 2.1.3 Basic Requisites l SSID It is an identifier to identify the particular wireless LAN. So the same SSID should be configured to all stations to communicate in the same wireless network.
LAN networks in the same area, the channels should be apart more than 4 channels to avoid interferences. 2.1.4 Authentication and Security l Authentication A wireless LAN station should get authentication from the AP in the infrastructure mode. There are the Open system and the Shared key for the authentication methods. l WEP (Wired Equivalent Privacy) The WEP is a secure protocol for wireless LAN. There are two kinds of WEP method - 64 bits and 128 bits key.
[Figure 2.2.1] Connect between CMAX Module and a PC 2.2.1 Making Wireless LAN Network Even though you connect an AP on your network, wireless LAN network could not be made automatically. You should configure values of items which related with wireless network. Please follow the below steps. l Connect the CMAX Module through serial port Start the WLAN Module Manager on your PC. Push the “Connect” button after Selecting a COM port, User ID and User Password as the same values with the your COM port.
IP Address, User ID and User Password as the same values with the CMAX Module. [Figure 2.2.1.2] Connect through WLAN l Configuring Wireless LAN Parameters Move to the [Network] menu and setting SSID as the same values with the AP’s. Then, move to the [Authentication] menu and setting security options. Finally, Click the “Update” button. Please ask the manufacturer of the AP, when you want to know about setting the AP’s value. [Figure 2.2.1.
This step is for setting both CMAX Module and your PC to be located the same network. If only they are, the TCP connection between them can be established. Setting of the PC l Add or change the IP address of the network adapter on your PC like following. Get into the menu of [Windows Control Panel] >> [Network Connections] >> [Properties of the Network Adapter - with right click of your mouse]. Then, you can show the properties of [Internet Protocol (TCP/IP).
