Ad-hoc Wireless LAN Configuration The simplest WLAN configur ation is an in depend ent (Ad-hoc) WLAN that connect s a set of computers with wireless adapters (A, B, C).

Appendix E Wir eless LANs ZyWALL USG 300 User’s Guide 1021 An ESSID (ES S IDentification) uniquely id entifies each ESS . All access points and their associated wirel ess clients within the same ESS must have the same ESSID in order to comm u nicate.

Appendix E Wirele ss LA Ns ZyWALL USG 300 User’s Guide 1028 Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange For ad ded security , certificate-based au thentications (EAP- TLS, EAP- TTLS and PEAP) use dynamic keys for data encryption .
Appendix E Wir eless LANs ZyWALL USG 300 User’s Guide 1029 use Advanc ed 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 k eys that are dynami cal ly generated and d istributed by the authentication server .
Appendix E Wirele ss LA Ns ZyWALL USG 300 User’s Guide 1030 authentication. These two features are op tional and ma y not be supported in all wireless dev ices. K ey caching allows a wireless client to store th e PMK it deriv e d through a successful authentication wit h an AP .
Appendix E Wir eless LANs ZyWALL USG 300 User’s Guide 1031 4 The RADIUS server distributes the PMK to the AP . The AP th en sets u p a key hierarchy and management system, usin g the PMK to dynamica lly generate unique data encryption k eys.
Appendix E Wirele ss LA Ns ZyWALL USG 300 User’s Guide 1032 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create tempor al encryption keys. They use these keys to encrypt data exchanged between them.
Appendix E Wir eless LANs ZyWALL USG 300 User’s Guide 1033 Antenna Overview An antenna couples RF signals onto air . A transmi tter within a wireless device sends an RF signal to the antenna, whic h propagates the signal through the air . The antenna also operates in reverse by capturing RF signals from the air .
Appendix E Wirele ss LA Ns ZyWALL USG 300 User’s Guide 1034 • Omni-directional antennas send the RF sign al out in all directions on a horizontal plane. The cover age area is torus-sh aped (like a donut) which makes these antennas ideal for a room environment.
