5. Modifying a Wireless Network 5.1 Infrastructure Mode and Ad Hoc Mode You can set the Wireless Network Adapter to work in either Infrastructure mode or Ad Hoc mode.Infrastructure Mode In infrastructure mode, devices communicate with each other by first going through an Access Point (AP). Wireless devices can communicate with each other or can communicate with a wired network. When one AP is connected to wired network and a set of wireless stations, it is referred to as a BSS (Basic Service Set). Ad Hoc Mode Ad-hoc mode is also called “peer-to-peer mode” or “Independent Basic Service Set (IBSS)”. In ad hoc mode, devices communicate directly with each other without using an Access Point (AP). 22

 Ad Hoc Net Start: Specifies a band to establish an Ad Hoc network if nomatching SSID is found. three options are available: 802.11b, 802.11a,and 802.11g. 802.11b Range: Options are Normal Range and Extended Range. Thisfunction can let user to determine the transfer range in 802.11b mode. Extended Range can prolong the transfer range with a lower data transmitting rate.  Scan Mode: Options are Active Scan,Passive Scan and Auto. In Active Scan, the driver sends out the probe request frames from each channel and collects the response frames from the responding. In Passive Scan, the driver scan each requested channel, listening the beacons on each channel.  Transmit Power: This setting allows you to change the output power of the PC Card to increase or decrease the coverage area,but can not exceed the authorized max. power output.  QoS: Disables or enables the PC Card to cooperate in a network using QoS(Quality of Service).  Country: Select the country where this PC Card will operate. ALERT! Different countries have different regulations that affect which channels can be used. You should always choose the country where you are physically located to avoid using an illegal channel.(When this product sells to US, client will disable the other frequency of outside USA)  2.4 GHz Preamble: Allows Ad-Hoc compatibility with other 2.4 GHz devices.

Appendix A: FAQ about WLAN 1. 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 anetwork. Consult the application’s user guide to determine whether it supports operation over a network. 2. Can I play computer games with other members 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. 3. What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique developed bythe 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). 4. What is DSSS? What is FHSS? And what are their differences? Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changesfrequency in a pattern that is known to both transmitter and receiver. Properlysynchronized, the net effect is to maintain a single logical channel. To an unintendedreceiver, FHSS appears to be short-duration impulse noise. Direct-SequenceSpread-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.31

5. Would the information be intercepted while transmitting on air? WLAN features two-fold protection in security. On the hardware side, as with DirectSequence Spread Spectrum technology, it has the inherent security feature ofscrambling. On the software side, WLAN offers the encryption function (WEP) to enhance security and access control. 6. What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or128-bit shared key algorithm, as described in the IEEE 802.11 standard. 7. What is infrastructure mode? When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point.8. 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 accesspoint. Before using the roaming function, the workstation must make sure that it is the same channel number with the access point of dedicated coverage area.To achieve true seamless connectivity, the wireless LAN must incorporate a numberof different functions. Each node and access point, for example, must alwaysacknowledge 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 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 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 node’s RF transmitter regularly checks the system to determine whether it is in touch with the original access point or whether itshould 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. 32
