Computers in a wireless LAN must be configured to share the same radio channel. The Instant WirelessTM Series Adapter provides access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is called an Infrastructure configuration. A group of Instant WirelessTM Series Adapter users and an Instant WirelessTM Network Access Point compose a Basic Service Set (BSS). Each Instant WirelessTM Series Adapter PC in a BSS can talk to any computer in a wired LAN infrastructure via the Instant WirelessTM Network Access Point. Package Contents · · · · · · · One Instant WirelessTM Network Access Point One AC Power Adapter One Setup CD-ROM One User Guide One Quick Installation and Registration Card (not shown) Two Detachable Antennae One USB Cable An infrastructure configuration extends the accessibility of an Instant WirelessTM Series Adapter PC to a wired LAN, and doubles the effective wireless transmission range for two Instant WirelessTM Series Adapter PCs. Since the Wireless Network Access Point is able to forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled. The use of a unique ID in a BSS is essential. All Instant WirelessTM Series Adapter PCs configured without roaming options in an independent BSS must be configured with a BSS ID used in the BSS. The wireless LAN Infrastructure configuration is appropriate for enterprisescale wireless access to a central database, or as a wireless application for mobile users. Roaming Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be configured as an Extended Service Set (ESS). This continuous network allows users to roam freely within an ESS. All Instant WirelessTM Series Adapter PCs within one ESS must be configured with the same ESS ID and use the same radio channel. Before enabling an ESS with roaming capability, choosing a feasible radio channel and optimum Wireless Network Access Point position is recommended. Proper Wireless Network Access Point positioning combined with a clear radio signal will greatly enhance performance. 3 System Requirements · A PC with USB Support or Ethernet Connection · Windows 95, 98, Millennium, NT version 4.0, or 2000 Professional · 500 kbytes of free disk space for utility and driver installation · A 10 Mbps Category 3 or Better network RJ-45 connection Linux/Unix Users: Though these operating systems are not supported by Linksys, the Wireless Access Point should work in these environments.

The Authentication Type default is set to Open System, in which the sender and the recipient do NOT share a secret key. Each party generates its own key-pair and asks the receiver to accept the randomlygenerated key. Once accepted, this key is used for a short time only. Then a new key is generated and agreed upon. Shared Key is when both the sender and the recipient share a secret key. Preamble Type. The preamble defines the length of the CRC block for communication between the Access Point and the roaming Network Card. (High network traffic areas should use the shorter preamble type.) Select the appropriate preamble type and click the Apply button to set it. Basic Rates. The basic transfer rates should be set depending on the speed of your wireless network. Verify that you've set the correct basic rate for your wireless network before clicking the Apply button. The Auto Rate Fall Back setting should be checked to make your wireless network flexible for roaming wireless devices. As wireless devices move away from the Access Point, the transfer rate will automatically fall back to the most optimum rate allowed. · · · Before making any changes to the Advanced tab, please check your wireless settings as these changes will alter the effectiveness of the Wireless Network Access Point. In most cases, these settings do not need to be changed. · Fragmentation Threshold Value. The value should remain at its default setting of 2,346. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance.

Read the description below to solve your problems. If you can't find an answer here, check the Linksys website at www.linksys.com. What is the purpose of antenna diversity and when should it be used? When used, how should it be set-up? The dual antennae on the Access Point are probably best explained using this example. Take television, if you have ever had the old "rabbit ear type of antenna" and saw reflections on TV (called "ghosts"), then you moved the antenna and the reflections "went away." (Using two antennae allows us to "MOVE AWAY" from reflections that cause us to lose or have to retransmit data.) They should be used indoors as outdoor reflections are rare. As long as both antennae cover roughly the same area, this is fine. The Info tab displays general information about Linksys and the Access Point SNMP Manager. The SNMP Configuration Utility's copyright date and version number are listed as well as the Utility's firmware version. At the bottom of the screen, you will find a button that will access Linksys' web page (once your Internet connection is properly set up), the email address for technical support, and the phone number to call for technical support. · Stations. This shows the MAC addresses of those machines making wireless connections to the Access Point. · Statistics. This displays the connection statistics for your wireless and Ethernet connections. · TrapLog. This displays the information on any SNMP messages read by your Access Point. Frequently Asked Questions Can the Wireless Network Access Point act as my DHCP Server? No. The Access Point is nothing more than a wireless hub, and as such, cannot be configured to handle DHCP capabilities. Can I run an application from a remote computer over the wireless network? This will depend on whether or not the application is designed to be used over a network. Consult the application's user guide to determine if it supports operation over a network. Can I play multiplayer games with other users of the wireless network? Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game's user guide for more information. What is the IEEE 802.11b standard? The IEEE 802.11b Wireless LAN standards subcommittee is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufacturers to communicate. 46 47 Instant WirelessTM Series What IEEE 802.11 features are supported? The product supports the following IEEE 802.11 functions: · CSMA/CA plus Acknowledge protocol · Multi-Channel Roaming · Automatic Rate Selection · RTS/CTS feature · Fragmentation · Power Management What is Ad-hoc? An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent wireless LAN. An Ad-hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. What is Infrastructure? An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to a central database, or wireless application for mobile workers. What is Roaming? Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single Wireless Network Access Point. Before using the roaming function, the workstation must make sure that it is the same channel number as the Wireless Network Access Point of the dedicated coverage area. To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and Wireless Network Access Point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links Wireless Network Access Points and nodes. In such a system, the user's end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each Wireless Network Access Point and the distance of each Wireless Network Access Point to the wired backbone. Based on that information, the node next selects the right Wireless Network Access Point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. Wireless Network Access Point As the user moves on, the end node's RF transmitter regularly checks the system to determine whether it is in touch with the original Wireless Network Access Point or whether it should seek a new one. When a node no longer receives acknowledgment from its original Wireless Network Access Point, it undertakes a new search. Upon finding a new Wireless Network Access Point, it then re-registers, and the communication process continues. What is BSS ID? A specific Ad-hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID. What is ESSID? An Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS could roam freely between BSSs while maintaining a continuous connection to the wireless network stations and Wireless Network Access Points. What is ISM band? The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high speed wireless capabilities in the hands of users around the globe. What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS). 48 49 Instant WirelessTM Series What is DSSS? What is FHSS? And what are their differences? Frequency Hopping Spread Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct Sequence Spread Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. Would the information be intercepted while transmitting on air? WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side, the WLAN series offers the encryption function (WEP) to enhance security and access control. Users can set it up depending upon their needs. Can Instant WirelessTM products support file and printer sharing? Instant WirelessTM products perform the same function as LAN products. Therefore, Instant WirelessTM products can work with Netware, Windows NT/2000, or other LAN operating systems to support printer or file sharing. What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802.11 standard. What is a MAC Address? The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a computer logs on to the network, the MAC address of a device stays the same, making it a valuable identifier for the network. Wireless Network Access Point Glossary Ad-hoc Network - An ad-hoc network is a wireless network or other small network in which some of the network devices are part of the network only for the duration of a communications session, while others stay in close proximity to the rest of the network. Default Gateway - The router used to forward all traffic that is not addressed to a station within the local subnet. DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Using the Internet's set of protocol (TCP/IP), each machine that can connect to the Internet needs a unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine. Without DHCP, the IP address must be entered manually at each computer and, if computers move to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network. DHCP uses the concept of a "lease" or amount of time that a given IP address will be valid for a computer. The lease time can vary depending on how long a user is likely to require the Internet connection at a particular location. It's especially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP addresses. DHCP supports static addresses for computers containing Web servers that need a permanent IP address. DNS - The Domain Name System (DNS) is the way that Internet domain names are located and translated into Internet Protocol (IP) addresses. A domain name is a meaningful and easy-to-remember "handle" for an Internet address. 50 51 Instant WirelessTM Series DSSS - Also known as "Direct Sequence Spread Spectrum," this is a variety of radio transmission methods that continuously change frequencies or signal patterns. Direct Sequence Spread Spectrum (DSSS), which is used in CDMA, multiplies the data bits by a very fast, pseudo-random bit pattern (PN sequence) that "spreads" the data into a large coded stream that takes the full bandwidth of the channel. Dynamic IP Address - An IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server. Network devices that serve multiple users, such as servers and printers, are usually assigned static IP addresses. ESS - More than one BSS in a network. FHSS - Also known as "Frequency Hopping Spread Spectrum." Frequency Hopping Spread Spectrum (FHSS) continuously changes the center frequency of a conventional carrier several times per second according to a pseudo-random set of channels, while chirp spread spectrum changes the carrier frequency. Because a fixed frequency is not used, illegal monitoring of spread spectrum signals is extremely difficult, if not downright impossible depending on the particular method. Firmware - Programming that is inserted into programmable read-only memory, thus becoming a permanent part of a computing device. IEEE - The Institute of Electrical and Electronics Engineers. The IEEE describes itself as "the world's largest technical professional society--promoting the development and application of electrotechnology and allied sciences for the benefit of humanity, the advancement of the profession, and the wellbeing of our members." The IEEE fosters the development of standards that often become national and international standards. The organization publishes a number of journals, has many local chapters, and has several large societies in special areas, such as the IEEE Computer Society. Infrastructure - An infrastructure network is a wireless network or other small network in which the wireless network devices are made a part of the network through an Access Point that connects them to the rest of the network. Wireless Network Access Point IP Address - In the most widely installed level of the Internet Protocol (Internet Protocol) today, an IP address is a 32-binary digit number that identifies each sender or receiver of information that is sent in packets across the Internet. When you request an HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address you're sending a note to. At the other end, the recipient can see the IP address of the Web page requester or the e-mail sender and can respond by sending another message using the IP address it received. IPCONFIG - A utility that provides for querying, defining and managing IP addresses within a network. A commonly used utility, under Windows NT and 2000, for configuring networks with static IP addresses. ISP - An ISP (Internet service provider) is a company that provides individuals and companies access to the Internet and other related services such as website building and virtual hosting. LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). MAC Address - The MAC (Media Access Control) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. mIRC - mIRC runs under Windows and provides a graphical interface for logging onto IRC servers and listing, joining, and leaving channels. Network Mask - also known as the "Subnet Mask." PCMCIA - The PCMCIA (Personal Computer Memory Card International Association) is an industry group organized in 1989 to promote standards for a credit card-size memory or I/O device that would fit into a personal computer, usually a notebook or laptop computer. Ping (Packet INternet Groper) - An Internet utility used to determine whether a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response. 53 52 Instant WirelessTM Series RJ-45 - A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices. Roaming - The ability to use a wireless device and be able to move from one access point's range to another without losing the connection. Static IP Address - A permanent IP address that is assigned to a node in a TCP/IP network. Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field for subnets. TCP (Transmission Control Protocol) - A method (protocol) used along with the Internet Protocol (Internet Protocol) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet. TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP. UDP (User Datagram Protocol) - A communications method (protocol) that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a datagram) from one computer to another. Unlike TCP, however, UDP does not provide the service of dividing a message into packets (datagrams) and reassembling it at the other end. Specifically, UDP doesn't provide sequencing of the packets that the data arrives in. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. Network applications that want to save processing time because they have very small data units to exchange (and therefore very little message reassembling to do) may prefer UDP to TCP. 54 Wireless Network Access Point UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64bit shared key algorithm, as described in the IEEE 802.11 standard. WINIPCFG - Configuration utility based on the Win32 API for querying, defining, and managing IP addresses within a network. A commonly used utility, under Windows 95, 98, and Millennium, for configuring networks with static IP addresses. 55 Instant WirelessTM Series Wireless Network Access Point Baseband Processor: MAC Controller: HFA 3861B or HFA 3863 MAC Atmel AT76C510 13 - 20 dBm at maximum radiation direction 1.2 Transmitter RF Output Power: Frequency Stability: 4 mW/MHz Within + 25 ppm Specifications Standards: Channels: IEEE 802.3 (10BaseT), IEEE 802.11b (Wireless) 11 Channels (US, Canada) 13 Channels (Europe) 14 Channels (Japan) One 10BaseT RJ-45 Port, One USB Port 10BaseT: UTP Category 3 or Better USB: USB Cable Indoors: Up to 30M (100 ft.) @ 11 Mbps Up to 50M (165 ft.) @ 5.5 Mbps Up to 70M (230 ft.) @ 2 Mbps Up to 91M (300 ft.) @ 1 Mbps Outdoors: Up to 152M (500 ft.) @ 11 Mbps Up to 270M (885ft.) @ 5.5 Mbps Up to 396M (1300 ft.) @ 2 Mbps Up to 457M (1500 ft.) @ 1 Mbps Up to 11Mbps (Wireless), 10Mbps (Ethernet) Power, Act, Link (Wired - Link/Activity) 1.1 General Radiation Power: Ports: Cabling Type: Operating Range (Wireless): Data Modulation Type: BPSK (1/5.5Mbps) / QPSK (2/11 Mbps) CCK (5.5/11 Mbps) 1.3 Power Power Voltage: Power Consumption: Environmental Dimensions: Unit Weight: 7.31" x 6.16" x 1.88" (186mm x 154mm x 48mm) 20.5 oz.
