APPENDIX A WiMAX Security Wireless security is vital to protect your wireless communications. Without it, information transmitted over the wireless network would be accessible to any networking device within range. User Authentication and Data Encryption The WiMAX (IEEE 802.16) standard employs user authentication and encryption to ensure secured communication at all times. User authentication is the process of confirming a users identity and level of authorization.
Appendix A WiMAX Security Authentication Determines the identity of the users. Authorization Determines the network services available to authenticated users once they are connected to the network. Accounting Keeps track of the clients network activity. RADIUS is a simple package exchange in which your base station acts as a message relay between the MS/SS and the network RADIUS server.
Appendix A WiMAX Security Authorization request and reply The MS/SS presents its public certificate to the base station. The base station verifies the certificate and sends an authentication key (AK) to the MS/SS. Key request and reply The MS/SS requests a transport encryption key (TEK) which the base station generates and encrypts using the authentication key. Encrypted traffic The MS/SS decrypts the TEK (using the authentication key).

APPENDIX D IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.
Appendix D IP Addresses and Subnetting Figure 212 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term subnet is short for subnetwork. A subnet mask has 32 bits.
Appendix D IP Addresses and Subnetting Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Table 124 Subnet Masks BINARY DECIMAL 1ST OCTET 2ND OCTET 3RD OCTET 4TH OCTET 8-bit mask 11111111 00000000 00000000 00000000 255.0.0.0 16-bit mask 11111111 11111111 00000000 00000000 255.255.0.0 24-bit mask 11111111 11111111 11111111 00000000 255.255.255.

If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.
Appendix D IP Addresses and Subnetting IP Address Conflicts Each device on a network must have a unique IP address. Devices with duplicate IP addresses on the same network will not be able to access the Internet or other resources. The devices may also be unreachable through the network. Conflicting Computer IP Addresses Example More than one device can not use the same IP address.
Appendix D IP Addresses and Subnetting Conflicting Computer and Router IP Addresses Example More than one device can not use the same IP address. In the following example, the computer and the routers LAN port both use 192.168.1.1 as the IP address. The computer cannot access the Internet. This problem can be solved by assigning a different IP address to the computer or the routers LAN port.
APPENDIX E 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).
Appendix E Wireless LANs Figure 219 Basic Service Set ESS 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. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood.
Appendix E Wireless LANs Figure 220 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a channel different from an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.
Appendix E Wireless LANs Figure 221 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. RTS/CTS is designed to prevent collisions due to hidden nodes.
Appendix E 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. Short and long refer to the length of the synchronization field in a packet.
Appendix E 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.
Appendix E Wireless LANs Determines the network services available to authenticated users once they are connected to the network. Accounting Keeps track of the clients 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.
Appendix E 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. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client.
Appendix E 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 security configuration screen.
Appendix E 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. TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server.
Appendix E 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. The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration" wireless client. However, you must run Windows XP to use it.
Appendix E Wireless LANs 3 The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them.
Appendix E Wireless LANs Antenna Overview 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. 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 and IEEE 802.11g) or 5GHz (IEEE 802.
Appendix E Wireless LANs Positioning Antennas In general, antennas should be mounted as high as practically possible and free of obstructions. In point-topoint application, position both antennas at the same height and in a direct line of sight to each other to attain the best performance. 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.
