Page 4 of 39 LG GoldStream Chapter 1 Introduction To The Wireless LAN A wireless LAN (WLAN) is a flexible data communication system implemented as an extension to, or as an alternative for, a wired LAN within a building or campus. Using electromagnetic waves, 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. WLANs have gained strong popularity in a number of vertical markets, including the health-care, retail, manufacturing, warehousing, and academic arenas. These industries have profited from the productivity gains of using hand-held terminals and notebook computers to transmit real-time information to centralized hosts for processing. Today WLANs are becoming more widely recognized as a general-purpose connectivity alternative for a broad range of business customers. 1.1 What’s Wireless LAN? Wireless LANs use electromagnetic airwaves (radio and infrared) to communicate information from one point to another without relying on any physical connection. Radio waves are often referred to as radio carriers because they simply perform the function of delivering energy to a remote receiver. The data being transmitted is superimposed on the radio carrier so that it can be accurately extracted at the receiving end. This is generally referred to as modulation of the carrier by the information being transmitted. Once data is superimposed (modulated) onto the radio carrier, the radio signal occupies more than a single frequency, since the frequency or bit rate of the modulating information adds to the carrier. Multiple radio carriers can exist in the same space at the same time without interfering with each other if the radio waves are transmitted on different radio frequencies. To extract data, a radio receiver tunes in (or selects) one radio frequency while rejecting all other radio signals on different frequencies. In a typical WLAN configuration, a transmitter/receiver (transceiver) device, called an access point, connects to the wired network from a fixed location using standard Ethernet cable. At a minimum, the access point receives, buffers, and transmits data between the WLAN and the wired network infrastructure. A single access point can support a small group of users and can function within a range of less than one hundred Page 5 of 39 LG GoldStream to several hundred feet. The access point (or the antenna attached to the access point) is usually mounted high but may be mounted essentially anywhere that is practical as long as the desired radio coverage is obtained. End users access the WLAN through wireless LAN adapters, which are implemented as PC cards in notebook computers, or use PCI adapters in desktop computers. WLAN adapters provide an interface between the client network operating system (NOS) and the airwaves (via an antenna). The nature of the wireless connection is transparent to the NOS. 1.2 Wireless LAN Standard and Structure ¦ Wireless LAN Standard – IEEE802.11b The widespread acceptance of WLANs depends on industry standardization to ensure product compatibility and reliability among the various manufacturers. The Institute of Electrical and Electronics Engineers (IEEE) ratified the original 802.11 specifications in 1997 as the standard for wireless LANs. That version of 802.11 provides for 1 Mbps and 2 Mbps data rates and a set of fundamental signaling methods and other services. The most critical issue affecting WLAN demand has been limited throughput. The data rates supported by the original 802.11 standard are too slow to support most general business requirements and have slowed adoption of WLANs. Recognizing the critical need to support higher data-transmission rates, the IEEE recently ratified the 802.11b standard (also known as 802.11 High Rate) for transmissions of up to 11 Mbps. With 802.11b, WLANs will be able to achieve wireless performance and throughput comparable to wired Ethernet. Outside of the standards bodies, wireless industry leaders have united to form the Wire-less Ethernet Compatibility Alliance (WECA). WECA’s mission is to certify cross-vendor interoperability and compatibility of IEEE 802.11b wireless networking products and to promote that standard for the enterprise, the small business, and the home. Members include WLAN semiconductor manufacturers, WLAN providers, computer system vendors, and software makers. ¦ Wireless LAN Network Equipment 802.11 defines two pieces of equipment, a wireless station, which is usually a PC equipped with a wireless network interface card (NIC), and an access point (AP), which acts as a bridge between the wireless and wired networks. An access point usually Page 6 of 39 LG GoldStream consists of a radio, a wired network interface (e.g., 802.3), and bridging software conforming to the 802.1d bridging standard. The access point acts as the base station for the wireless network, aggregating access for multiple wireless stations onto the wired network. Wireless end stations can be 802.11 PC Card, PCI. ¦ Wireless LAN Network Configuration The 802.11 standard define two modes: infrastructure mode and ad hoc mode (or independent or peer-to-peer). l Ad Hoc Mode Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service Set, or IBSS) is simply a set of 802.11 wireless stations that communicate directly with one another without using an access point or any connection to a wired network. This mode is useful for quickly and easily setting up a wireless network anywhere that a wireless infrastructure does not exist or is not required for services, such as a hotel room, convention center, or airport, or where access to the wired network is barred (such as for consultants at a client site). Independent Basic Service Set (IBSS) Figure 1. Ad Hoc Mode l Infrastructure Mode In infrastructure mode, the wireless network consists of at least one access Page 7 of 39 LG GoldStream point connected to the wired network infrastructure and a set of wireless end stations. This configuration is called a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or more BSSs forming a single sub-network. Since most corporate WLANs require access to the wired LAN for services (file servers, printers, Inter-net links) they will operate in infrastructure mode. Distribution System (DS) Ethernet (802.3) Access Point (AP) Service Set (SS) – Multiple Figure 2. Infrastructure Mode ¦ Roaming Wireless communication is limited by how far signals carry for given power output. WLANs use cells, called microcells, similar to the cellular telephone system to extend the range of wireless connectivity. At any point in time, a mobile PC equipped with a WLAN adapter is associated with a single access point and its microcell, or area of coverage. Individual microcells overlap to allow continuous communication within wired network. They handle low power signals and “hand off” users as they roam through a given geographic area. The 802.11 MAC layer is responsible for how a client associates with an access point. Page 8 of 39 LG GoldStream When an 802.11 client enters the range of one or more APs, it chooses an access point to associate with (also called joining a Basic Service Set), based on signal strength and observed packet error rates. Once accepted by the access point, the client tunes to the radio channel to which the access point is set. Periodically it surveys all 802.11 channels in order to assess whether a different access point would provide it with better performance characteristics. If it determines that this is the case, it reassociates with the new access point, tuning to the radio channel to which that access point is set. Reassociation usually occurs because the wireless station has physically moved away from the original access point, causing the signal to weaken. In other cases, Reassociation occurs due to a change in radio characteristics in the building, or due simply to high network traffic on the original access point. In the latter case this function is known as “load balancing,” since its primary function is to distribute the total WLAN load most efficiently across the available wireless infrastructure. This process of dynamically associating and reassociating with APs allows network managers to set up WLANs with very broad coverage by creating a series of overlapping 802.11b cells throughout a building or across a campus. To be successful, the IT manager ideally will employ “channel reuse,” taking care to set up each access point on an 802.11 DSSS channel that does not overlap with a channel used by a neighboring access point. Backbone Network Access Point (AP) Inter-Cell Roaming Figure 3. Roaming Page 9 of 39 LG GoldStream ¦ BSS, ESS and SS ID The basic service set (BSS) is the basic building block of WLAN network. Minimum WLAN BSS may be consist of only two stations. Using access point (AP) and network distribution systems (DS), WLAN service set can be extended arbitrary size – extended service set (ESS). Each service set has its network ID (SSID). All the service sets within an ESS network can have same service ID so that the ESS can support inter-cell ROAMING.

If you click on Rescan button, LAN card program searches other new channel that currently used one. Throughput (Byte/sec) shows transmit/receive data rate. Link Quality shows measured radio link quality. If the link quality is bad, your computer may not communicate with other client computers. Otherwise (; fair, good…), there is no problem to communicate with other clients. Signal Strength is similar to Link Quality information but slightly differ from it. But usually, the quality level moves simultaneous with the Link Quality level. Network Configuration Page 25 of 39 LG GoldStream Mode: You can select wireless LAN network mode – Infrastructure or Ad-hoc mode Infrastructure Mode This mode is used to set up a connection to a wired Ethernet network. This mode requires an GOLDSTREAM Access Point to gain access to the wired network. Ad Hoc Mode This mode is used to set up a small, temporary network between two or more computers. For example, you might set up an ad hoc network between computers in a conference room so users can share information in a meeting. SSID: The Service Set Identifier (SSID) controls access to a given wireless network. This value MUST match the SSID of any and all GoldStream Access Points that you want to communicate with. If the value does not match, access to the system is not granted. The SSID can be up to 32 case-sensitive characters. Tx Rate : The transmission rate at which the data packets are transmitted by the client or AP. You can set this value to 1~2Mbps, 5.5Mbps, 11Mbps or Fully Automatic. PS Mode : PS stands for Power Saving Mode. Currently, the PS mode does not supported. After changing the setting in the Configuration change dialog box, click on Apply Changes button. It takes a few seconds to set changes that you made. Encryption - WEP Page 26 of 39 LG GoldStream In order to do secure communication over the wireless LAN network, wireless LAN module provides encryption function - WEP. There are two ways to generate WEP key. This key is an important in protecting the illegal access to the wireless networks. If you want to use WEP function, the AP also set the same WEP key value with you. And all the users who want to communicate with you must use same key with each other. You can select WEP key Disable in Configuration dialog box, the communication between clients and AP does not secure. There are two ways to generate the WEP key. One is by entering any text in the Passphrase. And click on Generate button. It will generate four WEP keys; Key 1, Key 2, Key 3, Key 4. You can select any key for the security. If you do not select any key, Key 1 is selected in default. The other way is by entering Key value directly from the keyboard. Select the Key number and use that Key for accessing the AP. If the Key is not entered correctly, a client cannot access any other client or AP. This Key value protects the illegal access to Page 27 of 39 LG GoldStream the wireless network resources. As the wireless channel is more prone to the illegal access, WEP provides the users safe wireless LAN network access. Caution If you use WEP function, your network throughput degrade Page 28 of 39 LG GoldStream 3.2 PCI Card Installation This section describes the procedures for installing the client adapter. Before You Start For the client adapter to be used with a computing device, the device must be equipped with a PCI or ISA expansion slot. Check the documentation that came with your computer for details on the differences between PCI and ISA expansion slots. Ask your system administrator for the following information, which you may need to provide during driver installation: • Your Wireless Client Name • Your Wireless SSID • Your computer's unique client name and workgroup name • For Windows NT, a free interrupt and I/O address. • For your network account, your user name and password • If you’re not using a DHCP server, your IP address, gateway address, and subnet mask After unpacking the client adapter, make sure the following items are present and in good condition: • GoldStream LW1100P Series PCI Client Adapter • Standard 2 dBi dipole antenna • LW1100P Series software and documentation CD for Windows 95/98 Windows ME, Windows 2000 Installing the PCI Client Adapter If any item is damaged or missing, contact your client adapter supplier. Save all shipping and packing material in order to repack the unit should service be required. This section provides instructions for installing a client adapter on a computer using one of the Windows operating systems. Before you begin, examine the client adapter. The antenna connector and Status and Page 29 of 39 LG GoldStream Activity LEDs will face out of your computer, and will be visible when you put the cover back on. The bottom edge of the card is the connector you will insert into an empty expansion slot in your computer. 3.2.1 Installing PCI Card Adapter 1. Turn off the computer and all its components. 2. Remove the computer cover. 3. Remove the screw from the top of the CPU back panel above an empty expansion slot. This screw is used to hold the metal bracket on the back panel. 4. Tilt the client adapter to allow the antenna connector and LED lights to slip through the opening in the CPU back panel. 5. Press the client adapter into the empty slot until its connector is firmly seated. Page 30 of 39 LG GoldStream Caution Do not force the client adapter into the slot. Forcing it will damage both the card and the slot. If the card does not go in easily, remove the card and reinsert it. 6. Reinstall the screw to the top of the CPU back panel. 7. The client adapter comes with one 2dBi dipole antenna. With the unit powered off, attach the antenna to the antenna connector on the client adapter. Caution Do not over-tighten the antenna connector; finger-tight is sufficient. Position the antenna vertically for best omni-directional signal reception. Page 31 of 39 LG GoldStream 3.2.2 Installing PCI Card Driver The installation process of PCI card driver program is the same as that of PC card installation. So, you may refer above 3.1.1 Installing the PC Card Driver for Windows Operating Systems except Step 4. In the Step 4 stage, you should choose PCI instead PC Card (PCMCIA). All the other process is the same as PC card installation process. 3.2.3 PCI Card Network Configuration The installation process of PCI card driver program is the same as that of PC card installation. So, you may refer above 3.1.2 PC Card (PCMCIA Card) Network Configuration Page 32 of 39 LG GoldStream 3.3 Troubleshooting In this chapter, we have listed various problems that you may encounter during the installation and have also listed possible solutions. The system tray wireless monitor icon is always red â Change your location or the location of the antenna by a few feet and try again. â Make sure the client adapter card is securely inserted in the expansion slot. â Make sure the antenna is securely attached. â Make sure that your computers SSID have the same one with other clients. â Set all clients to the same channel number in case of Ad-hoc network mode. â Make sure that you are with in the range of an AP. If your computer cannot be associated with any AP, it cannot communicate with other clients. â Make sure the antenna is securely attached. The system tray wireless monitor icon â is always yellow You can communicate with other clients but air link quality is not good so data transferred slowly. In this case, you may move your computer or wireless LAN card antenna to higher position than current state or closer position with AP. Cannot find wireless monitor icon in the taskbar Page 33 of 39 LG GoldStream â Make sure that the PC card is started as automatic in the device applet of the Control panel. â Double click on the PC card icon in the Control panel. Click on GoldStream adapter and then click on the properties button. It should say that the driver started correctly. â Make sure the drivers were installed correctly. If there is some warning or error, uninstall drivers and software through Add/Remove Program, remove the Wireless LAN card and reinstall the drivers following the manual. Cannot connect to some computers â Make sure that the client computer is with in the range of an AP and uses same SSID with you. â Make sure that your TCP/IP is set properly and correctly. Page 34 of 39 LG GoldStream Appendix Appendix A Cell Planning (Radio Range) This section provides general guidelines on factors that influence network performance Cell Site Survey Because of differences in component configuration, placement and physical environment, every network application is a unique installation. Before installing the system, users should perform a site survey to determine the optimum utilization of networking components and to maximize range, coverage and network performance. Here are some operating and environmental conditions you should consider: • Data Rates Radio signal sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. There will be a decrease in receiver threshold sensitivity as the radio data rate increases. • Antenna Type and Placement (PCI card only) Proper antenna configuration is a critical factor in maximizing radio range. As a general guide, range increases in proportion to antenna height. For a detailed explanation of antenna types and configurations along with guidelines on selecting antennas for specific environments, see the documentation that comes with your antenna. • Physical Environments Clear or open areas provide better radio range than closed or filled areas. Also, the less cluttered the work environment, the greater the range. • Obstructions A physical obstruction such as metal shelving or a steel pillar can hinder the performance of the client adapter. Avoid locating the computing device in a location where there is a metal barrier between the sending and receiving antennas. Page 35 of 39 LG GoldStream • Building Materials Radio penetration is greatly influenced by the building material used in construction. For example, drywall construction allows greater range than concrete blocks. Metal or steel construction is a barrier to radio signals. Enhancing Coverage The system architecture options of the wireless station and GoldStream Access Points provide for a variety of coverage alternatives and flexibility. The system can be designed to provide a wide coverage area with minimal overlap or coverage with heavy overlap. The latter improves system performance and protection against downtime in the event of a component failure. By arranging the GoldStream Access Points so the overlap in coverage area is minimized, a large area can be covered with minimal system cost. The total bandwidth available to each mobile station will depend on the amount of data each mobile station desires to transfer and the number of stations located in each cell. Seamless roaming is supported as a mobile station moves in and out of range of each GoldStream Access Point, thereby maintaining a constant connection to the wired LAN. Each device in the radio network must be configured with the same Service Set Identifier (SSID) to provide the roaming capability. Multiple systems can operate in the same vicinity. The architecture provides multiple channels, which can coexist in the same area with virtually no interference to each other. In this mode, each system must be configured with different Service Set Identifiers (SSID) and different channels, which prevent clients from roaming to GoldStream Access Points of a different wireless system.
