ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Chapter 4 Wireless LAN This chapter discusses how to configure Wireless LAN screens on the ZyAIR. 4.1 Wireless LAN Basis This section provides basic background information on the wireless LAN screens. 4.1.1 Channel A channel is the radio frequency(ies) used by IEEE 802.11b wireless devices. Channels available depend on your geographical area.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 4-1 RTS/CTS When station A sends data to the ZyAIR, it might not know that 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.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge 4.1.5 Fragmentation Threshold A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the ZyAIR will fragment the packet into smaller data frames. A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge 4.3.1 Data Encryption WEP provides a mechanism for encrypting data using encryption keys. The values for the keys must be set up exactly the same on the APs or other peer ad-hoc wireless computers as they are on the ZyAIR to encrypt and decrypt data. Your ZyAIR allows you to configure up to four 64-bit or 128-bit WEP keys, but only one key can be enabled at any one time. 4.3.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge must then use the AP’s default WEP key to encrypt the challenge text and return it to the AP, which attempts to decrypt the message using the AP’s default WEP key. If the decrypted message matches the challenge text, the wireless station is authenticated. When your ZyAIR's authentication method is set to open system, it will only accept open system authentication requests. The same is true for shared key authentication.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Roaming In an infrastructure network, wireless stations are able to switch from one AP to another as they move between the coverage areas. During this period, the wireless stations maintain uninterrupted connections to the network. This is roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate AP depending on the signal strength, network utilization or other factors.

ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Appendix D Wireless LAN and IEEE 802.11 A wireless LAN (WLAN) provides a flexible data communications system that you can use to access various services (navigating the Internet, email, printer services, etc.) without the use of a cabled connection. In effect a wireless LAN environment provides you the freedom to stay connected to the network while roaming around in the coverage area. WLAN is not available on all models.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Spread Spectrum (DSSS) and Frequency-Hopping Spread Spectrum (FHSS), in the 2.4 to 2.4825 GHz unlicensed ISM (Industrial, Scientific and Medical) band. The third method is infrared technology, using very high frequencies, just below visible light in the electromagnetic spectrum to carry data.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge points can provide wireless coverage for an entire building or campus. All communications between stations or between a station and a wired network client go through the access point. The Extended Service Set (ESS) shown in the next figure consists of a series of overlapping BSSs (each containing an Access Point) connected together by means of a Distribution System (DS).
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Appendix E Antenna Selection and Positioning Recommendation An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Choosing the right antennas and positioning them properly increases the range and coverage area of a wireless LAN.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge environment. With a wide coverage area, it is possible to make circular overlapping coverage areas with multiple access points. • Directional antennas concentrate the RF signal in a beam, like a flashlight. The angle of the beam width determines the direction of the coverage pattern; typically ranges from 20 degrees (less directional) to 90 degrees (very directional). The directional antennas are ideal for hallways and outdoor point-to-point applications.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Appendix F Power over Ethernet Specifications You can use a power over Ethernet injector to power this device. The injector must comply to IEEE 802.3af. Chart F-1 Power over Ethernet Injector Specifications Power Output 15.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Appendix G IP Subnetting IP Addressing Routers “route” based on the network number. The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1. IP addresses are categorized into different classes. The class of an address depends on the value of its first octet.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge A class “A” address (24 host bits) can have 224 –2 hosts (approximately 16 million hosts). Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a value of 0 to 127. Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B” address has a valid range of 128 to 191.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge sequence of ones beginning from the left most bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits. Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge Divide the network 192.168.1.0 into two separate subnets by converting one of the host ID bits of the IP address to a network number bit. The “borrowed” host ID bit can be either “0” or “1” thus giving two subnets; 192.168.1.0 with mask 255.255.255.128 and 192.168.1.128 with mask 255.255.255.128. In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits.
ZyAIR B-420 Wireless LAN Ethernet Adapter and Bridge to an actual host for the first subnet is 192.168.1.1 and the highest is 192.168.1.126. Similarly the host ID range for the second subnet is 192.168.1.129 to 192.168.1.254. Example: Four Subnets The above example illustrated using a 25-bit subnet mask to divide a class “C” address space into two subnets.
