5 Glossary

 

 

 ٛ 

1. IEEE 802.11 Standard

 

 ٛ 

The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry. 

 

 ٛ 

2. Access Point

 

 ٛ 

An internetworking device that seamlessly connects wired and wireless networks together. 

 ٛ 

 ٛ 

3. Ad Hoc

 

 ٛ 

An Ad Hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent wireless LAN. 

Ad Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. 

 ٛ 

 ٛ 

4. BSSID

 

A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSSID. 

 ٛ

 

 ٛ 

5. DHCP

 

Dynamic Host Configuration Protocol - a method in which IP addresses are assigned by server dynamically to clients on the 
network. DHCP is used for Dynamic IP Addressing and requires a dedicated DHCP server on the network. 

 ٛ

 

 ٛ 

6. Direct Sequence Spread Spectrum

 

This is the method the wireless cards use to transmit data over the frequency spectrum. The other method is frequency 
hopping. Direct sequence spreads the data over one frequency range (channel) while frequency hopping jumps from one 
narrow frequency band to another many times per second. 

 ٛ

 

 ٛ 

7. ESSID

 

An Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be 
configured as an Extended Service Set (ESS). Users within an ESS could roam freely between BSSs while served as a 
continuous connection to the network wireless stations and Access Points within an ESS must be configured with the same 
ESSID and the same radio channel. 

 ٛ

 

 ٛ 

8. Ethernet

 

Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users must be wired to the network at all 
times to gain access. 

 ٛ

 

 ٛ 

9. Gateway

 

 ٛ 

A gateway is a hardware and software device that connects two dissimilar systems, such as a LAN and a mainframe. In 

Internet terminology, a gateway is another name for a router. Generally a gateway is used as a funnel for all traffic to the 
Internet. 

 ٛ

 

 ٛ 

10. IEEE

 

Institute of Electrical and Electronics Engineers Infrastructure. An integrated wireless and wired LAN is called an 
Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless 
application for mobile workers. 

 ٛ

 

 ٛ 

11. ISM Band

 

 ٛ 

The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the so-called ISM 

(Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available 
worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands 
of users around the globe. 

 ٛ

 

 ٛ 

12. Local Area Network (LAN)

 

 ٛ 

A LAN is a group of computers, each equipped with the appropriate network adapter card connected by cable/air, that share 

applications, data, and peripherals. All connections are made via cable or wireless media, but a LAN does not use telephone 
services. It typically spans a single building or campus. 

 ٛ

 

 ٛ 

13. Network

 

A network is a system of computers that is connected. Data, files, and messages can be transmitted over this network. 
Networks may be local or wide area networks. 

 ٛ

 

 ٛ 

14. Protocol

 

 ٛ 

A protocol is a standardized set of rules that specify how a conversation is to take place, including the format, timing, 

sequencing and/ or error checking. 

 ٛ

 

 ٛ 

15. SSID

 

 ٛ 

A Network ID unique to a network. Only clients and Access Points that share the same SSID are able to communicate with 

each other. This string is case-sensitive.
