  • Page 56: Ess

    G-470 User’s Guide 6.1.2 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). An ESSID (ESS IDentification) uniquely identifies each ESS.

  • Page 57: Ssid

    6.2.2 SSID The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network. Wireless devices must have the same SSID to communicate with each other. 6.2.3 RTS/CTS A hidden node occurs when two stations are within range of the same access point, but are not within range of each other.

  • Page 58: Fragmentation Threshold

    G-470 User’s Guide If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), 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. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.

    Types of EAP Authentication This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information. Your wireless LAN device may not support all authentication types.

  • Page 90: Table 24 Comparison Of Eap Authentication Types

    G-470 User’s Guide EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected.
  • Page 91 Table 24 Comparison of EAP Authentication Types Deployment Difficulty Client Identity Protection WPA(2) Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication.

  • Page 92: User Authentication

    G-470 User’s Guide The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped.

    Figure 53 WPA-PSK Authentication WPA(2) with RADIUS Application Example You need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system. 1 The AP passes the wireless client's authentication request to the RADIUS server.
