Glossary Glossary 802.11b An IEEE standard for a wireless network that operates at 2.4 GHz with rates up to 11 Mbps. Association Describes the establishment and maintenance of a wireless link between devices. (If security is enabled, the devices cannot do anything but exchange security credentials with this link).
Glossary network devices with a variety of information, such as IP addresses, required for their operation. GPRS – General Packet Radio Service A packet-based mobile communications system building on GSM.
Glossary serial number unique to every mobile device. The IMEI number is used by the mobile network to identify valid devices. IP – Internet Protocol A part of a suite of protocols that effectively defines the Internet as we know it. Specifies addressing and control information for routing data packets over networks.
Glossary used to carry IP (and other protocol) data between the service provider and your computer. Private IP Address A private IP Address is typically assigned to a client on a LAN (Local Area Network) and is not used outside the LAN. Private IP addresses are typically used when multiple computers share the same Internet connection.
Glossary TCP is responsible for dividing data up into packets for delivery and reassembling them at the destination. IP is responsible f or delivering the packets from source to destination. When TCP and IP are bundled with higher-level applications such as HTTP, FTP, Telnet, and so on, TCP/IP refers to this whole suite of protocols.
Glossary stronger data encryption method; TKIP. WPA data encryption is based on a WPA master key. The master key is derived from the passphrase and the network name (SSID) of the device. WPA2 – Wi-Fi Protected Access 2 An enhanced version of WPA. For data encryption, WPA2 uses AES instead of TKIP.
