26Device ConfigurationWhen configuring a wireless network, take note of the following points:❍Start by determining the areas to be networked, the number of users and the type of devices to be used. Then determine the number of access points required and where they should be placed.❍An access point provides a data rate of up to 11 Mbps, which is shared by all wireless clients in the area covered by the access point. If two access points are placed close to each other, you can optimize your bandwidth by setting them to different channels.❍Optimize the performance of the wireless network by ensuring that the distance between two access points is not too large. In most buildings, wireless network cards operate within a range of 100 to 300 feet (30 to 91 meters), depending on the thickness and structure of the walls. Under normal conditions, an access point provides a coverage of up to 150 feet (46 meters). However, in offices with walls or cube walls, the coverage is only around 80 feet (24 meters). ❍Radio waves can pass through walls and glass but not metal. If the signal on the other side of a wall is weak, it may be that the wall has reinforcing metal in its structure. Install another access point to circumvent this problem or move the access point to another location.❍Floors usually have metal girders and metal reinforcing struts that weaken radio waves.Configuring a Wireless Network

32What Is A Wireless Net-B W hat Is A W ireless N etwork?Wireless network is a revolutionary way of connecting devices to each other or to a Local Area Network wirelessly through the use of radio frequency waves.This means that you will be able to move around in a room or move from one floor to another without being disconnected from the network. In most companies, a wireless network is an extension of a wired network. In small offices or hard-to-wire areas, it may be the only network solution.Using wireless network has many advantages! Here are some of them:❍Easy Installation — Installing a wireless network is easy, convenient, and fast. ❍Cost Effective — You do not have to install cables into your walls and floors. Multiple Internet users will be able to share a single IP address.❍Speed — A wireless network provides data speeds of up to 11 Mbps, which increases the access rate to shared resources.❍Mobility — Unlike wired networks, a wireless network allows you to move around on a floor or building, or even across buildings, and still remain connected to the network.❍Flexibility — Adding new users and rearranging office space is convenient as it does not require any additional wiring.❍Scalability — You can choose to configure your wireless network to Ad-hoc mode or Infrastructure mode. In Ad-hoc mode, a wireless laptop can communicate with other wireless stations directly. In Infrastructure mode, one or more wireless computers are connected to an Access Point via radio waves, and the Access Point connects these wireless laptops to other wireless and wired laptops or computers.Features and Benef its

33What Is Wireless Net-An Ad-hoc network is also known as a Peer-to-Peer network. Ad-hoc mode allows for wireless-to-wireless communication. Select this mode when connecting to other wireless adaptors, which comply to the 802.11b standard. Users on the network can share files, printers, drives and other peripherals, and access the Internet using a shared modem. However, users can only communicate with other wireless network stations that are in the wireless network workgroup and that are within a fixed range.In Infrastructure mode, a wireless adaptor communicates with a wired network using an access point. It allows for roaming between a wireless station and access point, while maintaining connection to all network resources. In Infrastructure mode, a user on a wireless network can access an existing wired network to connect to the Internet, E-mail, transfer files, and share a printer. Moreover, the access point manages the bandwidth to maximize bandwidth utilization.Ad-hoc NetworkInfrastructure Network

39GlossaryDGlossaryThis appendix explains the technical terms used in this manual.Access pointA networking device that transparently bridges wireless computers and laptops to a wired local network.Ad-hoc modeA small peer-to-peer network mode, in which wireless Notebooks are connected to each other directly without using an access point. Some of the wireless Notebooks are part of the network for a limited duration. They are also in close proximity with the rest of the network. According to the IEEE 802.11b specification, Ad-hoc mode is referred to as an independent basic service set.American Standard Code for Information Interchange (ASCII)ASCII is the most common format for text files in computers and on the Internet. In an ASCII file, each alphabetic, numeric, or special character is represented with a 7-bit binary number (a string of seven 0s or 1s). 128 possible characters are defined. AntennaA device that intercepts radio frequency (RF) waves from the atmosphere and converts them to corresponding signal voltages.BandwidthA measure of the maximum rate of data transfer. A higher bandwidth allows more data transmission in a given period of time. For digital services, the bandwidth is usually expressed in bits or bytes per second.Basic Service Set (BSS)A group of wireless stations and an access point using the same ID (SSID).BinaryA number system that has only two digits, 0 and 1.

40GlossaryBridgeA hardware device that links two or more physical networks and manages the transfer of data between these networks. The two networks connected can be alike or dissimilar.BroadbandA transmission media that can handle the transmission of multiple messages at different frequencies, at one time. Broadband signals use analog carriers.ChannelA channel is a separate path through which signals can flow.Decibels Per Milliwatt (dBm)A unit of measurement used to express relative difference in power or intensity, relative to 1mW.Dynamic Host Configuration Protocol (DHCP)A method of assigning a temporary IP address to a host, such as a computer, connected on a specific network. With dynamic addressing, a particular host may have a different IP address each time it connects to the network.DigitalData expressed as a string of 0s and 1s. Each of these digits is referred to as a bit (and a string of 8 bits that a computer can address individually as a group is a byte).DNS ServerA server that contains both the English and numerical addresses of all computers connected to the Internet. When you specify an e-mail or IP address using the “English” domain name, the DNS server will return the corresponding numeric address.Domain NameA domain name locates an organization or other entity on the Internet.Domain Name System (DNS)This allows you to specify a symbolic name, a meaningful and easy-to-remember “handle,” instead of an Internet Protocol address.

41GlossaryDriverA program that a computer uses to control the operation of a peripheral device, such as a keyboard, modem, monitor, card, or cable.Direct Sequence Spread Spectrum (DSSS)A digital modulation technique that spreads data transmissions across the entire available frequency band in a pre-arranged scheme. Under DSSS, each bit of data to be transmitted is encoded with a redundant pattern called a chip. The chipping code is known only to the sending and receiving stations, making it difficult for an intruder to intercept and decipher the encoded wireless data. DSSS is used in IEEE 802.11b networks.Dynamic IP addressSee DHCP.EncryptionA procedure to convert a file from its original form to one that can be read only by the intended recipient.Extended Service Set Identity (ESSID)It is an ASCII string and can be as long as 32 characters. It is used by a wireless network. Wireless stations with a different ESSID from your network’s ESSID cannot connect to your network.EthernetA local-area network (LAN) protocol that supports data transfer rates of 10 Mbps.

IP corresponds to the Network layer (layer 3) in the ISP/OSI model.IP AddressThe address for a computer on a TCP/IP network. The IP address identifies a particular machine on a network. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be 0 to 255, for example, 11.160.10.240 is an IP address. Any machine connected to the Internet is assigned an IP address.Industrial, Scientific and Medical (ISM) bandThere are four unlicensed bands for wireless networks and these bands are commonly known as ISM bands. These bands are found on the 900 MHz, 2.4 GHz and 5 GHz (two) frequency bands.Local Area Network (LAN)A computer network that spans a relatively small area. Most LANs are confined to an office, single building, or group of buildings.Light Emitting Diode (LED)An electric component that emits light (turns ON) when current flows through it.Kilobits per second (Kbps)A measure of data transfer speed.

NAT provides a type of firewall security by hiding internal IP addresses. Since they are used internally, such IP addresses will not be in conflict with those used by other companies and organizations.Network MaskSee Subnet Mask.Network Interface Card (NIC)A card that is installed in a computer so that it can be connected to a network. The NIC manages the flow of network information to and from the computer.Personal Computer Memory Card International Association (PCMCIA)An industry group organized in 1989 to promote standards for a card-size memory or I/O device that would fit into a personal computer, usually a Notebook or computer.PCMCIA CardA card-size memory or I/O device that connects to a personal computer, usually a Notebook or computer. The PCMCIA card has a 68-pin connector that connects into a slot in the computer.

45GlossaryPacket Internet Groper (PING)An Internet program used to determine whether a specific IP address is accessible. It works by sending a packet to the specified address and waiting for a reply. PING is used primarily to troubleshoot network connections.PreambleA preamble is a signal, in the form of series of pulses, used in network communication to synchronize the transmission timing between two or more systems. There are two options, Short and Long. The Short option improves throughput performance.ProtocolA set of agreed-upon rules for transmitting data between two devices. A user’s laptop must support the right protocols for the laptop to communicate with other computers.RebootWhen a computer is shut down and restarted, it is rebooting.RJ-11A connector/socket for two pairs (four wires) of twisted pair cables that are used primarily to connect telephone equipment in the United States.RJ-45A connector/socket for four pairs of twisted pair cables that are used commonly to connect computers onto a local-area network, especially to the Ethernet. The only difference between an RJ-45 and RJ-11 connector is that an RJ-45 connector is slightly wider.RouterA hardware device that connects two separately functional networks using the same or different protocols. Routers look at the destination addresses on the packets passing through them and then decide which route to send them on.Request to Send (RTS) ThresholdThis threshold refers to when your PCMCIA card sends out RTS frames to reserve bandwidth for maximum data transmission. If a transmitted data frame is larger than the threshold value, the RTS frame sent out will request for more bandwidth.

46GlossaryService Set Identity (SSID)A group name shared by all members of an IEEE 802.11 standard wireless network. Only wireless devices with the same SSID are allowed to establish connections.Static IP addressA permanent IP address assigned to a computer (host) connected on a specific network.Subnet or SubnetworkAny network that is a part of a larger IP network and is identified by a subnet address.Subnet MaskA 32-bit string of a TCP/IP address — a part of which is the network address and another part the host address. A Subnet Mask is usually represented in dotted-decimal notation, for example, 255.255.255.0.SwitchA device used for connecting nodes in a star topology. In a star topology, all nodes are connected to a central switch. By monitoring packets, a switch learns which devices are connected to its ports and then sends a packet to the appropriate port only.Transmission Control Protocol/Internet Protocol (TCP/IP)A suite of communication protocols that are used by computers or networking devices on the Internet so that they can communicate with each other. TCP/IP uses several protocols, the two main being TCP and IP.10 Base-TA wiring standard used for Ethernet networks that can transmit data at up to 10 Mbps transmission using baseband unshielded twisted pair cables.
