point), the DSSS signal is recognized as the only valid signal, and interference is inherently rejected (ignored).
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.
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
FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes (hops) the carrier frequency of a conventional carrier several times per second according to a
Fragmentation - Breaking a data into smaller units when transmitting over a network medium that cannot support the original size of the data.
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.
Hop - The link between two network nodes.
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 Network - An infrastructure network is a group of computers or other devices, each with a wireless adapter, connected as an 802.11 wireless LAN. In infrastructure mode, the wireless devices communicate with each other and to a wired network by first going through an access point. An infra- structure wireless network connected to a wired network is referred to as a Basic Service Set. A set of two or more BSS in a single network is referred to as an Extended Service Set. Infrastructure mode is useful at a corporation scale, or when it is necessary to connect the wired and wireless networks.
IP (Internet Protocol) - The method or protocol by which data is sent from one computer to another on the Internet. It is a standard set of rules, procedures, or conventions relating to the format and timing of data transmission between two computers that they must accept and use to be able to understand each other.
IP Address - In the most widely installed level of the Internet Protocol (IP) today, an IP address is a
IRQ (Interrupt ReQuest) - A hardware interrupt on a PC. There are 16 IRQ lines used to signal the CPU that a peripheral event has started or terminated. Except for PCI devices, two devices cannot use the same line.
ISM band - The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made avail- able worldwide. This presents a truly revolutionary opportunity to place con- venient
ISP (Internet Service Provider) - A company that provides individuals and companies access to the Internet and other related services such as Web site building and virtual hosting.
LAN (Local Area Network) - A group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building).
