Introduction of Wireless Router For ADSL 1.1 Introducing the Wireless Router For ADSL Wireless Router For ADSL is a high performance wireless LAN access point that complies with the IEEE 802.11b and 802.11g wireless standards, which can be used to provide mobile clients with wireless access to an Ethernet network. The Wireless Router For ADSL supports Windows XP, Windows 2000, Windows Millennium Edition (ME), and Windows 98. A wireless LAN provides the same functionality of a wired network, but it eliminates the need to install networking cables and other networking equipment. A wireless LAN is not only easier to deploy, but it also allows for mobility through roaming. For example, the Wireless Router For ADSL can roam from a conference room to an office without being disconnected from the network.

*Available features vary by region/country. 1.2 System Requirements PC with the Operating Systems as follows: Windows XP, Windows 2000, Windows Millennium Edition (ME), or Windows 98 Second Edition 1.3 IEEE 802.11 Specifications The Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band in 1997. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11 standard operate at a data rate of either 1 or 2 Mbps. 1.3.1 802.11b In 1999, the IEEE modified the 802.11 standard to support direct sequence devices that can operate at speeds of up to 11 Mbps. The IEEE ratified this standard as 802.11b. 802.11b devices are backwards compatible with 2.4 GHz 802.11 direct sequence devices (that operates at 1 or 2 Mbps). 1.3.2 802.11a Also in 1999, the IEEE modified the 802.11 standard to support devices operating in the 5 GHz frequency band. This standard is referred to as 802.11a. 802.11a devices are not backward compatible with 2.4 GHz 802.11 or 802.11b devices. 802.11a radios use a radio technology called Orthogonal Frequency Division Multiplexing (OFDM) to achieve data rates of up to 54 Mbps. 1.3.3 802.11g In 2003, the IEEE ratified the 802.11g standard. This standard delivers the same 54Mbps maximum data rate as 802.11a, yet it offers an additional and compelling advantage-backward compatibility with 802.11b equipment. This means that 1 802.11b client cards will work with 802.11g access points, and 802.11g client cards will work with 802.11b access points. Note that 802.11b products cannot be upgraded to support 802.11g since the 802.11g radios use a different chipset than 802.11b devices. However, 802.11g products and 802.11b products can work in the same network. Because 802.11g and 802.11b operate in the same unlicensed band, the two standards share the same three channels, which can limit wireless capacity and scalability. with each other. An 802.11a device and an 11b/g device cannot communicate The Wi-Fi standard certified at 2.4 GHz ensures the wireless interoperability with other Wi-Fi (802.11b) certified devices. 1.4 Security Standards The Wireless Router For ADSL supports the following security standards

(features vary based on models):

Cisco Client Extension compatibility (including LEAP) Wired Equivalent Privacy (WEP) encryption using 64 bit, 128 bit or 152 bit encryption AES-CCM Encryption support Support for Windows 802.1x supplicants Wi-Fi Protected Access (WPA) encryption using PassPhrase (text string with at least 8 to 63 characters, it can be any combination of letters, numbers and other characters). 2 2. Installation This chapter describes how to install a Wireless Router For ADSL and software in a computer running Windows XP, Windows 2000, Windows Millennium Edition

(ME), or Windows 98 Second Edition (SE). Note for Windows XP Users:

The Windows XP operating system has a built-in feature known as Wireless Zero Configuration which has the capability to configure and control the Wireless Router For ADSL. 2.1 Compliance Review the following notes before installing a Wireless Router For ADSL. The Wireless Router For ADSL must comply with the following EMI, safety and ESD requirements:

1. Emission 802.11g FCC Part 15b, Part 15c EN 301 893 TELEC STD 33, STD- 66 North America Europe Japan 2. Safety Requirements North America Europe UL 60950 Ver.3 for USA, CSA C22.2 for Canada EN 60950 3. ESD Requirement Wireless Router For ADSL must withstand 15KV test voltage of electrostatic discharge under operational conditions. 2.2 Windows ME/ 98 SE Installation CD Requirement Before beginning the installation of a Wireless Router For ADSL, ensure that you have a Windows 98 SE or Windows ME installation CD available (depending on the computers operating system). Windows 98/ME users may be prompted to insert a Windows CD during the installation. You should not need a Windows CD when installing the card in a Windows XP or Windows 2000 computer. If you do not have a Windows 98/ME CD, it is possible that you already have the Windows installation files on your hard drive. These Windows installation files are known as Windows Cabinet or CAB files. The Cabinet files are commonly located in C:\WINDOWS\OPTIONS\INSTALL\ or C:\WINDOWS\OPTIONS\CABS\. Windows 98/ME users may need the Windows CD or Cabinet files to complete the installation of a Wireless Router For ADSL. It is recommended that you do not proceed with the installation until you have confirmed that you have one of these Windows installation media available. 3 2.3 Installation Install the driver before you insert the Wireless Router For ADSL into your computer.

Start menu>Control Panel>Add/Remove Programs 2. When you see the following window, click Remove and then click Next> to start uninstall. 3. Follow the instructions in the InstallShield Wizard window to uninstall Wireless Router For ADSL. 4 3. Wireless Topologies Wireless Router For ADSL looks and operates similar to Ethernet products. The only difference is that a radio replaces the wire between communicating devices. This means that all of your existing applications that operate over Ethernet will work with the Wireless Router For ADSL without any special wireless networking software. A wireless LAN can be configured for two different modes of operation. While each method has its advantages, one of them may be better suited for your needs. Review the following configurations to determine which mode is best for you. 3.1 Peer-to-Peer Group A Peer-to-Peer groupalso known as an Ad-Hoc network-- is the simplest to deploy and is ideal for small offices. Peer-to-Peer Group can be comprised of two or more wireless client configured to communicate with one another. Peer-to-Peer Group clients communicate directly with each other without using an access point

(AP). As a user on this type of network, you are able to quickly build up a wireless network in order to share files with other employees, print to a shared office printer, and access the Internet through a single shared connection. Ad-hoc networking is cost effective, because no other devices components are needed (such as access points, hubs or routers) in order to setup a network. However, with Ad-Hoc networking, your computer is only able to communicate with other nearby wireless clients. By using the off-the-shelf peer-to-peer network operating systems, each computer can dynamically connect and reconnect to the others with no additional configuration, as illustrated in Figure 1. Figure 1 Peer-to-Peer Group The Wireless Router For ADSL can communicate with an 802.11b or 802.11g Peer-to-Peer Group (but it can not dynamically switch between the two). Therefore, you must manually configure the wireless adapter to use one specific radio mode. 3.2 Access Point Infrastructure Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to extend that capability to wireless nodes. This is accomplished 5 by installing one or more Access Points on the Ethernet network. Access Points are devices that communicate with both the Ethernet network and the wireless network. An Access Point network is also referred to as an Infrastructure network. The key difference between an Infrastructure network and an Ad-Hoc network is the addition of one extra elementthe Access Point. The Access Point serves as the focal point for all data traffic on your wireless network, optimally managing all wireless data transactions. Additionally, the wireless Infrastructure can provide access to an existing wired LAN. This link allows computers on the wireless LAN to access the other wired LANs resources and tools, including Internet access, email delivery, file transfer, and printer sharing. See Figure 2 for example. Figure 2 Access Point Network You can use the Wireless Router For ADSL to communicate with 802.11g Access Points, 802.11b Access Points, or a combination of Access Point types. The wireless adapter is compatible with 802.11g and 802.11b Access Points from any vendor. 3.2.1 Roaming Among Multiple APs For larger environments, the Wireless Router For ADSL may roam from one Access Point to another while maintaining the same network connection. The Access Points establish coverage areas or cells similar in concept to those of a cellular phone network. The card will connect to any Access Point that is within range. The Wireless Router For ADSL supports both roaming between APs of the same type (for example, from one 802.11b AP to another) and roaming between APs of different types (for example, from an 802.11b AP to an 802.11g AP). Figure 3 illustrates roaming between APs of different radio types:

6 Figure 3 Roaming Between APs of Different Radio Types As the mobile client seamlessly switches from cell to cell, its network connectivity is preserved. The user can move freely between the Access Points in the network. When the roaming client leaves the transmission range of one Access Point, the card automatically detects the other Access Point(s) in the same vicinity to continue the network connection. 3.2.2 Roaming Principles A Wireless Router For ADSL can roam between 802.11g Access Points and 802.11b Access Points. All 802.11b and 802.11g Access Points that a client will roam between must have the same Network Name. Depending on the Wireless Mode selection, a user can roam among 802.11g and 802.11b Access Points. All workstations with Wireless Router For ADSL installed must use either a Network Name of any or the same Network Name as the Access Points that they will roam between. All Access Points and Wireless Router For ADSL must have the same security settings to communicate. The Access Points cells must overlap to ensure that there are no gaps in coverage and to ensure that the roaming client will always have a connection available. Access Points installed in the same vicinity that use the same frequency band

(2.4 GHz) should each use a unique, independent Channel to avoid potential interference. Access Points that use the same Channel should be installed as far away from each other as possible to reduce potential interference. Range i. Every environment is unique with different obstacles, barriers, materials, etc., and, therefore, it is difficult to determine the exact range that will be achieved without testing. Radio signals may reflect off of some obstacles or be absorbed by others depending on their construction. The IEEE 802.11 standards support multiple data rates that correspond to different transmission techniques. For wireless devices, there is a trade-off 7 between range and data rate. Transmission techniques that provide high data rates operate over short distances; techniques that provide slower data rates operate over greater distances. By default, the Wireless Router For ADSL automatically switches between these data rates to maintain a usable radio connection and achieve the best data rate based on the cards distance from the Access Point. Therefore, a client that is close to an Access Point will operate at a higher data rate than a client that is farther away from the Access Point. The Wireless Router For ADSL includes one integral omni-directional antenna. Proper antenna placement can help improve range. Here are some guidelines:

-

Try to keep the APs antennas free of obstructions (particularly metal objects). Use the Wireless Client Utility to evaluate the signal strength and link quality between 802.11 devices.

-

Refer to the documentation that came with your Access Points for suggestions on how to locate the AP and its antennas to maximize range and performance. 8 The following technical specification is for reference purposes only.
