[. . . ] 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. 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. Therefore, Instant Wireless products can work with NetWare, Windows NT/2000, or other LAN operating systems to support printer or file sharing. I am using 802. 11b-compliant wireless equipment but still cannot connect to my wireless network. Verify that you are using the same IP domain as that of your wireless network. Note: As with any Video system, image quality is only as good as the weakest link in the video signal chain. To achieve the best possible image quality with a wireless system, dedicate as much bandwidth as possible to the video presentation. Wireless Presentation Gateway Appendix A: Planning Your Wireless Network Network Topology A wireless LAN is exactly like a regular LAN, except that each network device in the LAN uses wireless technology to connect to the network. Computers in a wireless LAN must be configured to share the same radio channel. An integrated wireless and wired LAN is called an Infrastructure configuration. A group of wireless users and an access point compose a Basic Service Set (BSS). Each PC equipped with a wireless adapter in a BSS can talk to any computer in a wired LAN infrastructure. An infrastructure configuration extends the accessibility of a wireless user to a wired LAN, and doubles the effective wireless transmission range for wireless PCs. Since the access point is able to forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled. The Wireless LAN Infrastructure configuration is appropriate for enterprise-scale wireless access to a central database, or as a wireless application for mobile users. Roaming Infrastructure mode also supports roaming capabilities for mobile users. All wireless PCs within one Extended Service Set must be configured with the same SSID. Selecting a feasible radio channel and optimum access point position is recommended. Proper access point positioning combined with a clear radio signal will greatly enhance performance. 14 15 Instant WirelessTM Series Ad-hoc versus Infrastructure Mode Unlike wired networks, wireless networks have two different modes in which they may be set up: Infrastructure and Ad-hoc. Choosing between these two modes depends on whether or not the wireless network needs to share data or peripherals with a wired network or not. [. . . ] A typical scenario would be a location with multiple access points, where users can physically relocate from one area to another and easily maintain connectivity. RTS (Request To Send) - An RS-232 signal sent from the transmitting station to the receiving station requesting permission to transmit. SOHO (Small Office/Home Office) - Market segment of professionals who work at home or in small offices. Spread Spectrum - Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. [. . . ]
