Network Topology

A wireless network is a group of computers, each equipped with one or more wireless adapters. Computers in a wireless network must be configured to share the same radio channel to talk to each other. Several PCs equipped with wireless cards or adapters can communicate with each other to form an ad-hoc network without the use of an access point. Linksys also provides products to allow wireless adaptors to access wired network through a bridge such as the wireless access point, or wireless router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an infrastructure network can talk to any computer in a wired or wireless network via the access point or wireless router. An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may double the effective wireless transmission range for two wireless adapter PCs. Since an Access Point is able to forward data within a network, the effective transmission range in an infrastructure network may be more than doubled since Access Point can transmit signal at higher power to the wireless space. ad-hoc: a group of wireless devices communicating directly with each other (peer-to-peer) without the use of an access point. infrastructure: a wireless network that is bridged to a wired network via an access point.

Appendix A: Troubleshooting Frequently Asked Questions
CSMA/CA plus Acknowledge protocol Multi-Channel Roaming Automatic Rate Selection RTS/CTS feature Fragmentation Power Management What IEEE 802.11g features are supported? The product supports the following IEEE 802.11g functions: CSMA/CA plus Acknowledge protocol OFDM 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 Access Point. Before using the roaming function, the workstation must make sure that it is set to the same channel number as the 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 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 Access Points and nodes. In such a system, the users 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 Access Point and the distance of each Access Point to the wired backbone. Based on that information, the node next selects the right Access Point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone.
As the user moves on, the end nodes RF transmitter regularly checks the system to determine whether it is in touch with the original Access Point or whether it should seek a new one. When a node no longer receives acknowledgment from its original Access Point, it undertakes a new search. Upon finding a new Access Point, it then re-registers, and the communication process continues. What is the 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). 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 a variety of wireless security methods to enhance security and access control. Users can set it up depending upon their needs. Can Linksys wireless products support file and printer sharing? Linksys wireless products perform the same function as LAN products. Therefore, Linksys wireless 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. How do I avoid interference? Using multiple Access Points on the same channel and in close proximity to one another will generate interference. When employing multiple Access Points, make sure to operate each one on a different channel (frequency). How do I reset the Access Point? Press the Reset button on the back of the Access Point for about ten seconds. This will reset the unit to its default settings. How do I resolve issues with signal loss? There is no way to know the exact range of your wireless network without testing. Every obstacle placed between an Access Point and wireless PC will create signal loss. Leaded glass, metal, concrete floors, water, and walls will inhibit the signal and reduce range. Start with your Access Point and your wireless PC in the same room and move it away in small increments to determine the maximum range in your environment. You may also try using different channels, as this may eliminate interference affecting only one channel. Also, open the Access Points Web-based Utility. Click the Wireless tab and then the Advanced Wireless tab. Make sure the Output Power is set to 100%. Does the Access Point function as a firewall? No. The Access Point is only a bridge from wired Ethernet to wireless clients. I have excellent signal strength, but I cannot see my network. Wireless security, such as WEP or WPA, is probably enabled on the Access Point, but not on your wireless adapter (or vice versa). Verify that the same wireless security settings are being used on all devices in your wireless network. What is the maximum number of users the Access Point can handle?
No more than 63, but this depends on the volume of data and may be fewer if many users create a large amount of network traffic.
Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of Linksys products provide several network security features, but they require specific action on your part for implementation. So, keep the following in mind whenever you are setting up or using your wireless network.

Appendix B: Wireless Security Security Threats Facing Wireless Networks
WPA Personal. If you do not have a RADIUS server, select the type of algorithm, TKIP or AES, enter a password in the Pre-Shared key field of 8-63 characters, and enter a Group Key Renewal period time between 0 and 99,999 seconds, which instructs the AP or other device how often it should change the encryption keys. WPA Enterprise. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the AP or other device.) First, select the type of WPA algorithm, TKIP or AES. Enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Last, enter a Group Key Renewal period, which instructs the device how often it should change the encryption keys. WPA2. Wi-Fi Protected Access 2 (WPA2) is the latest security standard in Wi-Fi security. Two modes are available: Personal and Enterprise. WPA2 always uses AES (Advanced Encryption System) for stronger data encryption. WPA2 Personal. If you do not have a RADIUS server, enter a password in the Pre-Shared key field of 8-63 characters, and enter a Group Key Renewal period time between 0 and 99,999 seconds, which instructs the AP or other device how often it should change the encryption keys. WPA2 Enterprise. WPA2 used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the AP or other device.) First, enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Then, enter a Group Key Renewal period, which instructs the device how often it should change the encryption keys. WPA2 Mixed. WPA2 Mixed modes provide users an upgrade path from WPA to WPA2. You can have client devices running both WPA and WPA2 and the Access Point will automatically select the security method used by the client. Implementing encryption may have a negative impact on your networks performance, but if you are transmitting sensitive data over your network, encryption should be used. These security recommendations should help keep your mind at ease while you are enjoying the most flexible and convenient technology Linksys has to offer.

The introduction of the Linksys Business Series WAP4400N wireless Access Point answers the growing business need for access, speed, and security. The Access Point uses the very latest wireless networking technology, Wireless-N (draft 802.11n). By overlaying the signals of multiple radios, Wireless-Ns Multiple In, Multiple Out (MIMO) technology multiplies the effective data rate. Unlike ordinary wireless networking technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range and reduce dead spots in the wireless coverage area. The Linksys Wireless-N Access Point lets you connect Wireless-N (802.11n), Wireless-G (802.11g) or Wireless-B (802.11b) devices to your wired network so you can add PCs to the network with no cabling hassle. Power over Ethernet support makes it easy to install - you can mount the Access Point anywhere, even without ready access to a power plug. With appropriate Power Over Ethernet support at the other end, you only need to run one cable to the Access Point to deliver both data and power. Of course, you can also use the included AC adapter if your installation point has power available nearby. Moreover, the integrated QoS features provide consistent voice and video quality on both the wired and wireless networks, enabling the deployment of business qualilty VoIP and video applications. To protect your data and privacy, the Wireless-G Exterior Access Point supports both Wired Equivalent Privacy (WEP) and the industrial-strength wireless security of Wi-Fi Protected Access (WPA), encoding all your wireless transmissions with powerful encryption. The MAC Address filter lets you decide exactly who has access to your wireless network, and advanced logging keeps you apprised. Configuration is a snap with the web browser-based configuration utility. The Linksys Wireless-N Access Point with Power Over Ethernet is the best way to add wireless access to your existing business network.
Complies with IEEE draft 802.11n standards while at the same time being backwards compatible with 802.11b and g devices Standards-based POE (IEEE 802.3af ) or External DC power MIMO technology uses multiple radios to create a robust signal that travels farther and reduces dead spots Support for WMM provides improved QoS over wireless connections for better video and voice performance
