This manual provides a quick introduction to wireless technology and its application as it relates to networking. Take a moment to read through this manual and familiarize you with wireless technology. You should also give yourself some time to become familiar with your new wireless network. WWW.TwinMOS.COM Page 3 G101/G231 Series WLAN Card WIRELESS NETWORK OVERVIEW A wireless local area network (LAN) is a flexible data communications system implemented as an extension to, or as an alternative for, a wired LAN. Using radio frequency (RF) technology, wireless LANs transmit and receive data over the air, minimizing the need for wired connections. Thus, wireless LANs combine data connectivity with user mobility. A local area network that transmit and receive over the air typically in an unlicensed frequency such as the 2.4GHz band. A wireless LAN does not require lining up devices for line of sight transmission like IrDA. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a radio frequency over an area of several hundred to a thousand feet which can penetrate walls and other nonmetal barriers. Roaming users can be handed off from one access point to another like a cellular phone system. Laptops use wireless modems that plug into an existing Ethernet port or that are self contained on PC cards, while stand-alone desktops and servers use plug-in cards (ISA, PCI, etc.). Wireless LANs offer the following productivity, convenience, and cost advantages over traditional wired networks： Mobility - WLAN provide LAN users to access data in any location within the operating range of the WLAN. Ad-hoc management decisions based on real-time information can significantly improve worker efficiency. Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. Installation Flexibility - Wireless technology allows the network to go where wire cannot go. Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware can be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs can be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves and changes. Scalability - Wireless LAN systems can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to full infrastructure networks of thousands of users that enable roaming over a broad area. Installation Considerations Designed to go up to 300 feet (100 meters) indoors and up to 900 feet (273 meters) outdoors, G101/G231 WLAN adapter lets you access your network from virtually anywhere you want. Keep in mind, however, that the number and thickness of walls, ceilings or other objects that the wireless signals must pass thru may limit range. Typical ranges vary depending on the types of materials and background RF noise in your home or business. The key to maximizing range is to follow these basic principles: WWW.TwinMOS.COM Page 4 G101/G231 Series WLAN Card Keep the number of walls and ceilings between the access point and your receiving device to a minimum - Each wall or ceiling can reduce your TwinMOS G101/G231 Wireless product’s range from 3-90 feet (1-30 meters.) For some businesses or for a large residential home deployment, it may be more beneficial to have more than one access point with overlapping coverage. 1. Be aware of the direct line between Access Points, Residential Gateways, and Computers - A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Try to make sure that the Access Points and Adapters are positioned so that the signal will travel straight through a wall or ceiling for better reception. 2. Building Materials make a difference - A solid metal door or aluminum studs may have a negative effect on range. Try to position Access Points, Residential Gateways, and Computers so that the signal passes through drywall or open doorways and not other materials. 3. Make sure that the antenna is positioned for best reception by using the software signal strength tools included with your product. 4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices that generate RF noise, like microwaves, monitors, electric motors, etc. For the average residence, range should not be a problem. If you experience low or no signal strength in areas of your home that you wish to access, consider positioning the Access Point in a location directly between the Residential Gateways and/or Computers that will be connected. Additional Access Points can be connected to provide better coverage in rooms where the signal does not appear as strong as desired. Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through simplified configuration, enable movable LANs. WWW.TwinMOS.COM Page 5 G101/G231 Series WLAN Card G101/G231 WIRELESS NETWORK SCENARIOS The G101/G231 WLAN adapter enables you to: Connect your computer to an Ad-Hoc workgroup of wireless computing devices (see Figure 1-1 on page 6). Connect your computer to a Small Office/Home Office (SOHO) network that includes a Residential Gateway (RG) access point (see Figure 1-2 on page 7). Connect your computer to a Local Area Network (LAN) Infrastructure that includes Access Points, or other IEEE 802.11 compliant LAN systems (see Figure 1-3 and Figure 1-4). Expand the capabilities of your Access Points, to support wireless devices that have been equipped with G101/G231. Ad-Hoc Workgroup The Ad-Hoc workgroup configuration enables you to quickly set up a small wireless workgroup, where the workgroup participants can exchange files using features like “Files and Printer Sharing” as supported by Microsoft Networking. Figure 1-1 Ad-Hoc Wireless Workgroup You can use this option to setup a temporary or ad-hoc network in environments where no access points are available (for example in Small Office/Home Office (SOHO) environments). As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network. WWW.TwinMOS.COM Page 6 G101/G231 Series WLAN Card Home Networking With the TwinMOS G101/G231 WLAN adapter, wireless access to the Internet or other computers is at your fingertips. All you need to do is connect the wireless computers to an external cable, an xDSL or a ISDN modem and you are ready to： Share files and printers, and Access the Internet xDSL Figure 1-2 Connect to a Residential Gateway (RG) Enterprise Networking With the 11 Mbps Wireless LAN access point you can connect to a corporate Local Area Network (LAN) infrastructure to have wireless access to all network facilities. LAN Infrastructures may either be: Stand-alone wireless LANs (Figure 1-3). Wireless network infrastructures connected to an existing Ethernet network (Figure 1-4). Figure 1-3 Stand Alone Wireless LAN WWW.TwinMOS.COM Page 7 G101/G231 Series WLAN Card Figure 1-4 LAN Infrastructure It’s Easy The G101/G231 functions like any standard wired Ethernet card, but G101/G231 does not need any wires! Where an Ethernet card requires a cable connection to a hub and/or patch panel, the cable physically ties you down to the location of the wired connection. G101/G231 allows you to connect your computer to a Local Area Network (LAN) system from anywhere within the wireless coverage area. Expanding or re-designing your network is easy: Add or relocate access point, power-up your (new) wireless computers, and you’re done! Unlike Ethernet, TwinMOS G101/G231 will enable you to roam throughout the network while remaining connected to the LAN. Note：The G101/G231 wireless adapter is a radio product.

WWW.TwinMOS.COM Page 23 G101/G231 Series WLAN Card Using WPA of the Windows XP’s Utility Note1: Before use the WPA feature, please install Windows XP Service Pack 1 with Windows XP Support Patch for Wi-Fi Protected Access program Note2: Configure the card by Wireless built-in utility (Wireless Zero Configuration). Note3: All devices in the network should use the same encryption method to ensure the communication. Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security enhancements that strongly increase the level of data protection (encryption) and access control (authentication) for existing and future wireless LAN systems. The technical components of WPA include Temporal Key Integrity Protocol (TKIP) for dynamic key exchange, and 802.1x for authentication. Example : WWW.TwinMOS.COM Page 24 G101/G231 Series WLAN Card 1: Right click the icon to select “View Available Wireless Networks”. 2: Click “Advanced” button from “Wireless Network Connection”. WWW.TwinMOS.COM Page 25 G101/G231 Series WLAN Card 3: Click“Configure” button to configure the WPA function for the current network. Network Authentication •Open –No authentication is needed among the wireless network. •Shared – Only wireless stations using a shared key (WEP Key identified) are allowed to connecting each other. •WPA – This mode is for enterprise with an authentication server (Radius Server), WPA-enabled access point, and a WPA-enabled client. Once WPA is enabled, all clients and access points on the network must be WPA-enabled in order to access the network. •WPA-PSK – It is a special mode designed for home and small business users who do not have access to network authentication servers. In this mode, known as Pre-Shared Key, the user manually enters the starting password in their access point or gateway, as well as in each PC on the wireless network. WPA takes over automatically from that point, keeping unauthorized users that don't have the matching password from joining the network, while encrypting the data traveling between authorize ddevices. WWW.TwinMOS.COM Page 26 G101/G231 Series WLAN Card Data Encryption •WEP – In WPA or WPA-PSK mode, WEP is also able to be the encryption method for the transmission data. •TKIP – TKIP (Temporal Key Integrity Protocol) changes the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This insures much greater security than the standard WEP security. •AES – AES has been developed to ensure the highest degree of security and authenticity for digital information and it is the most advanced solution defined by IEEE 802.11i for the security in the wireless network.
