SCS Smart Channel Selection VSP Video Stream Protection RSSI Received Signal Strength Indication Wi-Fi A mark for WECA to check linking between wireless products. The name is originated from "Wireless Fidelity". WECA carries out an elaborate test and grants a Wi-Fi logo to a product that satisfies the linking standards. Wireless Bridge Tx (Client) or Rx ( Master) that uses a wireless network to connect between two different wired networks. Association Has a table that controls the packet route between Rx and Tx Maintains Rx and Tx. SSID Service Set Identifier SSID is a unique identifier of 32 bytes length added to the header of a packet transmitted through a WLAN. It is used like a password when Tx connects to BSS (basic service set). Rx or Tx must the same SSID. A Tx that does not know the unique of a certain BSS cannot access the BSS. WEP WEP (Wired Equivalent Privacy): An encryption standards prepared by IEEE 802.11 for WLAN security. There are various types of application developed to use encryption keys to strength security. Bandwidth Refers to the difference between the highest and lowest frequencies of a signal usable in a network. It means, commonly, the highest transmission speed or a capacity to transmit information and uses ‘bps’ its unit. DHCP DHCP allows the network administrator to manage and allocate IP addresses and to send new IP addresses when the computer connects to a different location of the network. Static IP Can use fixed IP addresses. There is no need for the administrator to allocate IP addresses. 802.11ac 802.11ac operates at 5G Hz’s V10.1 frequency bandwidth. PHY WDS Wireless Distribution System WDS forms a wireless network between Rx’s to provide the larger support range of wireless network than when one Rx is used. BSS Base Service Set Refer to a minimal size of WLAN formed based on a Rx if a wire network consists of multiple wireless Rx’s in the infrastructure mode.

EVB-A100 User Manual MBSS Multiple BSS AES Advanced Encryption Standard CCMP Counter Mode Encryption With CBC-MAC Protocol EAP Extensible Authentication Protocol ESS Extended Service Set Refers to a WLAN that consists of multiple Rxs. FAST Flexible Authentication via Secure Tunneling IV Initialization Vector PEAP Protected EAP PSK Pre-Shared Key TKI Temporal Key Integrity Protocol TLS Transport Layer Protocol WPA WiFi Protected Access WIFI security Protagoras WEP -> WPA - WPA2 Wi-Fi Protected Access (WPA, WPA2 ) is an authentication program carried out under the monitoring of Wi-Fi Alliance. It is a security protocol that indicates that the network equipment satisfies the security protocol established by Wi-Fi Alliance. WPA indicates that the existing LAN card operation complies with the expansion protocol standards completely and WPA2 mark indicates that the relevant device does the same. WPS WiFi Protected Setup Press the WPS buttons of the wireless Rx and wireless device (during the 120 seconds of waiting time) to establish connection without entering password: there are PBC, PIN, and NFC type. PMF Protected Management Frames Protects the frame. RADIUS Remote Authentication Dial-in User Service NSS Number of Spatial Streams DTIM Delivery traffic indication message Short GI Short Guard Interval The guard interval is a waiting time between sending data continuously in a wireless network to reduce the impact of data. For 802.11 a/g, it is 800 nsec, but for 802.11n, it is set to 400n sec so that the sub carrier can be used to compensate for the reduced guard interval to make the total throughout to reach 72Mbps. Reducing the guard is provided as a optional when a WLAN is established as interval needs agreement between the transmission and reception ends. OFDM Orthogonal Frequency Division Multiplexing MIMO Multi Input Multi Output MIMO is a multi I/O technology. The wireless quality depends on how far the signal is and which route the signal is received. MIMO uses multiple antennas to receive signals coming in along multiple paths (multipath) and operate data and recover them to original signals. 802.11g/b/g uses a single antenna or SISO (Single Input Output). Passphrase It is used instead of password to mean that the password should long enough.
