Instant WirelessTM Series
Download - To receive a file transmitted over a network. In a communications session, download means receive, upload means transmit.
Driver - A workstation or server software module that provides an interface between a device and the
DSSS
DTIM (Delivery Traffic Indication Message) - A DTIM field is a countdown field informing clients of the next window for listening to broadcast and mul- ticast messages. When the AP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP Clients hear the beacons and awaken to receive the broadcast and multicast messages.
Dynamic IP Address - An IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server. Network devices that serve multiple users, such as servers and printers, are usually assigned static IP addresses.
Encryption - A security method that applies a specific algorithm to data in order to alter the data's appearance and prevent other devices from reading the information.
ESS - More than one BSS in a network.
Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Has a transfer rate of 10 Mbps. Forms the underlying transport vehicle used by several
Wireless Network Access Point
FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes the center frequency of a conventional carrier several times per second accord- ing to a
Firmware - Programming that is inserted into programmable
Fragmentation - Breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet.
Gateway - A device that interconnects networks with different, incompatible communications protocols.
Hardware - Hardware is the physical aspect of computers, telecommunica- tions, and other information technology devices. The term arose as a way to dis- tinguish the "box" and the electronic circuitry and components of a computer from the program you put in it to make it do things. The program came to be known as the software.
Hub - The device that serves as the central location for attaching wires from workstations. Can be passive, where there is no amplification of the signals; or active, where the hubs are used like repeaters to provide an extension of the cable that connects to a workstation.
IEEE (The Institute of Electrical and Electronics Engineers) - The IEEE describes itself as "the world's largest technical professional society, promoting the development and application of electrotechnology and allied sciences for the benefit of humanity, the advancement of the profession, and the
The IEEE fosters the development of standards that often become national and international standards. The organization publishes a number of journals, has many local chapters, and several large societies in special areas, such as the IEEE Computer Society.
Infrastructure - An infrastructure network is a wireless network or other small network in which the wireless network devices are made a part of the network through the Access Point which connects them to the rest of the network.
