Page 129: Appendix D Wireless Lans
P P E N D I X Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
Page 130: Figure 92 Basic Service Set
Appendix D Wireless LANs Figure 92 Basic Service Set An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN.
Page 131: Figure 93 Infrastructure Wlan
Appendix D Wireless LANs Figure 93 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference.
Page 132: Figure 94 Rts/Cts
Appendix D Wireless LANs Figure 94 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.
Page 133: Table 35 Ieee 802.11G
Appendix D Wireless LANs If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Preamble Type Preamble is used to signal that data is coming to the receiver.
Page 134: Table 36 Wireless Security Levels
Appendix D Wireless LANs Wireless security methods available on the ZyXEL Device are data encryption, wireless client authentication, restricting access by device MAC address and hiding the ZyXEL Device identity. The following figure shows the relative effectiveness of these wireless security methods available on your ZyXEL Device.
Page 135 Appendix D Wireless LANs Determines the network services available to authenticated users once they are connected to the network. • Accounting Keeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server.
Page 136 Appendix D Wireless LANs For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.
Page 137: Table 37 Comparison Of Eap Authentication Types
Appendix D Wireless LANs Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen.
Page 138 Appendix D Wireless LANs Encryption Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.
Page 139: Figure 95 Wpa(2) With Radius Application Example
Appendix D Wireless LANs Wireless Client WPA Supplicants A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client.
Page 140: Figure 96 Wpa(2)-Psk Authentication
Appendix D Wireless LANs 4 The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them. Figure 96 WPA(2)-PSK Authentication Security Parameters Summary Refer to this table to see what other security parameters you should configure for each Authentication Method/ key management protocol type.
Page 141 Appendix D Wireless LANs Positioning the antennas properly increases the range and coverage area of a wireless LAN. Antenna Characteristics Frequency An antenna in the frequency of 2.4GHz (IEEE 802.11b) or 5GHz(IEEE 802.11a) is needed to communicate efficiently in a wireless LAN. Radiation Pattern A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area.
Page 142 Appendix D Wireless LANs For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omni-directional antennas mounted on a wall or ceiling, point the antenna down. For a single AP application, place omni-directional antennas as close to the center of the coverage area as possible.
