802.11b –

802.11b is one of the IEEE standards for wireless LANs and specifies a data transfer rate of

5.5 and up to 11 megabit per second in the 2.4 gigahertz radio band. 802.11b is recently given other

widespread names as Wi-Fi or Wireless Fidelity.

Ad-hoc Network

- Ad-hoc network, also known as peer-to-peer network, means a wireless network

which is composed only of stations. This type of network is created with a group of wireless-equipped

computers. With the wireless devices, each computer, functioning as a server and a client at the same

time, can establish a LAN to directly communicate with other computers without any access points

involved. It is easy to set up a peer-to-peer network; however, because all stations must be within a

specific distance in order to be capable of communicating with each other, it is also limited. Thus, such

a type of network is widely used at small networking requirements, like between a few computers or

devices at departmental scales.

IEEE –

IEEE, the Institute of Electrical and Electronics Engineers, is the world’s largest technical

professional society and is consisted of more than 366,000 members in approximately 150 countries.

As a leading authority on areas ranging from for computer engineering, biomedical technology and

telecommunications, IEEE endeavours to set more than 800 active consensus standards till now and

publish 30 percent of the world's literature in electrical engineering, computers and control technology.

Infrastructure Network –

Infrastructure network

allows you to communicate with wired LAN via an

access point. Unlike Ad-hoc network that all wireless-equipped stations within the range may directly

communicate with each other, clients of Infrastructure network can only transmit and receive data

through the use of a central access point. The associated access point also provides communication

with the wired network.

MAC Address –

The MAC (Media Access Control) address is the serial number of your Network

Interface card. It has been burnt into the chip and could not be changed. MAC address is thus unique.

While a computer on the network is transferring data, its MAC address is also conveyed and attached

to be part of the header of the data packets.

Roaming –

Roaming

is an ability to allow users from one cell (or BSS) to another without losing

connection via a wireless device.

SSID –

SSID

is short for

Service Set Identifier, a 32-character unique identifier for a workgroup of the

wireless network. An SSID of one WLAN should be different from that of others, so all access points
