3.2 Configuration 

This is the page where you can change the basic settings of the Access Point with the 
minimum amount of effort to implement a secure wireless network environment. 

 

 

SSID: 

Service Set Identifier, which is a unique name shared among all clients and 

nodes in a wireless network. The SSID must be identical for each clients and nodes in 
the wireless network. 

BSS Type: 

There are two types available for selection 

Infrastructure – to establish wireless communication with LAN and other wireless 

clients through the use the Access Points. 

Ad-Hoc – to establish point-to-point wireless communication directly with other 

wireless client devices such as wireless network PCI Adapter. 

Channel: 

The value of channel that AP will operate in. 

Tx Rate: 

Select the data rate for data transmission.

 

Power Mode: 

There are 3 modes to choose. 

Continuous Access Mode (default) – the WPC-0301 is constantly operating with full 

power and it consumes the most power. 

Maximum Power Save – the WPC-0301 consumes the least power and only operates 

when there is wireless network activity. 

Power Save – the WPC-0301 consumes the moderate level of power. 

Preamble: 

Select 

Long 

or 

Short 

Preamble type. Preamble is a sequence of bits

transmitted at 1Mbps that allows the PHY circuitry to reach steady-state 
demodulation and synchronization of bit clock and frame start. Two different 
preambles and headers are defined: the mandatory supported Long Preamble and 
header, which interoperates with the 1 Mbit/s and 2 Mbit/s DSSS specification (as 
described in IEEE Std 802.11), and an optional Short Preamble and header (as 
described in IEEE Std 802.11b). At the receiver, the Preamble and header are 
processed to aid in demodulation and delivery of the PSDU. The Short Preamble and 
header may be used to minimize overhead and, thus, maximize the network data 
throughput. However, the Short Preamble is supported only from the IEEE 802.11b 
(High- Rate) standard and not from the original IEEE 802.11. That means that stations 
using Short-Preamble cannot communicate with stations implementing the original 
version of the protocol. 
 
 

3.3 Encryption 

This is the page where you configure Security settings of your 802.11g wireless LAN 
PCMCIA Adapter 

 

 

Encryption: 

You can: 

Disable or

 

Enable

 the WEP data encryption feature. If 

enabled, it is required to select the 

Authentication mode

 from the next dropping list.     

Auth. Mode: 

There are three modes available to choose. 

 

11

 


background image

  

Open Authentication 

– the sender and receiver do not share secret Key for 

communication. Instead, each party generates its own key-pairs and asks the other 
party to accept it. The key is regenerated when the connection is established every 
time. 

  

Shared Authentication 

– the sender and receiver shares the common key for 

data communication, and the key is used for extended length of time. 

  

Auto 

– depend on the communication to establish, and automatically use the 

proper authentication mode. 
 
The following will only be activated to allow for configuration when 

Encryption 

is 

enabled. 

Default Key:

4. Glossary 

Access Point: 

An internetworking device that seamlessly connects wired and 

wireless networks. 

Ad-Hoc: 

An independent wireless LAN network formed by a group of computers, 

each with a network adapter. 

AP Client: 

One of the additional AP operating modes offered by 54Mbps Access 

Point, which allows the Access Point to act as an Ethernet-to-Wireless Bridge, thus a 
LAN or a single computer station can join a wireless ESS network through it. 

ASCII:

 American Standard Code for Information Interchange, ASCII, is one of the 

two formats that you can use for entering the values for WEP key. It represents 
English letters as numbers from 0 to 127. 

Authentication Type:

 Indication of an authentication algorithm which can be 

 

14

 


background image

supported by the Access Point: 
1. Open System: Open System authentication is the simplest of the available 
authentication algorithms. Essentially it is a null authentication algorithm. Any station 
that requests authentication with this algorithm may become authenticated if 802.11 
Authentication Type at the recipient station is set to Open System authentication. 
2. Shared Key: Shared Key authentication supports authentication of stations as either 
a member of those who knows a shared secret key or a member of those who does 
not. 

Backbone:

 The core infrastructure of a network, which transports information from 

one central location to another where the information is unloaded into a local system. 

Bandwidth:

 The transmission capacity of a device, which is calculated by how 

much data the device can transmit in a fixed amount of time expressed in bits per 
second (bps). 

Beacon:

 A beacon is a packet broadcast by the Access Point to keep the network 

synchronized. Included in a beacon are information such as wireless LAN service area, 
the AP address, the Broadcast destination addresses, time stamp, Delivery Traffic 
Indicator Maps, and the Traffic Indicator Message (TIM). 

Bit:

 A binary digit, which is either -0 or -1 for value, is the smallest unit for data. 

Bridge: 

An internetworking function that incorporates the lowest 2 layers of the OSI 

network protocol model. 

Browser:

 An application program that enables one to read the content and 

interact in the World Wide Web or Intranet. 

BSS: 

BSS stands for “Basic Service Set”. It is an Access Point and all the LAN PCs 

that associated with it. 

Channel: 

The bandwidth which wireless Radio operates is divided into several 

segments, which we call them “Channels”. AP and the client stations that it associated 
work in one of the channels. 

CSMA/CA: 

In local area networking, this is the CSMA technique that combines 

slotted time -division multiplexing with carrier sense multiple access/collision 
detection (CSMA/CD) to avoid having collisions occur a second time. This works 
best if the time allocated is short compared to packet length and if the number of 
situations is small. 

CSMA/CD:

 Carrier Sense Multiple Access/Collision Detection, which is a LAN 

access method used in Ethernet. When a device wants to gain access to the network, it 
checks to see if the network is quiet (senses the carrier). If it is not, it waits a random 
amount of time before retrying. If the network is quiet and two devices access the line 
at exactly the same time, their signals collide. When the collision is detected, they 
both back off and wait a random amount of time before retrying.

DHCP:

 Dynamic Host Configuration Protocol, which is a protocol that lets network 

administrators manage and allocate Internet Protocol (IP) addresses in a network.   
Every computer has to have an IP address in order to communicate with each other in 
a TCP/IP based infrastructure network. Without DHCP, each computer must be 
entered in manually the IP address. DHCP enables the network administrators to 
assign the IP from a central location and each computer receives an IP address upon 
plugged with the Ethernet cable everywhere on the network. 

DSSS: 

Direct Sequence Spread Spectrum. DSSS generates a redundant bit pattern for 

each bit to be transmitted. This bit pattern is called a chip (or chipping code). The 
longer the chip, the greater the probability that the original data can be recovered. 
Even if one or more bits in the chip are damaged during transmission, statistical 
techniques embedded in the radio can recover the original data without the need for 
retransmission. To an unintended receiver, DSSS appears as low power wideband 
noise and is rejected (ignored) by most narrowband receivers. 

Dynamic IP Address:

 An IP address that is assigned automatically to a client 

station in a TCP/IP network by a DHCP server.

 

Encryption:

 A security method that uses a specific algorithm to alter the data 

transmitted, thus prevent others from knowing the information transmitted. 

ESS:

 ESS stands for “Extended Service Set”. More than one BSS is configured to 

become Extended Service Set. LAN mobile users can roam between different BSSs in 
an ESS. 

ESSID:

 The unique identifier that identifies the ESS. In infrastructure association, the 

stations use the same ESSID as AP’s to get connected. 

Ethernet:

 A popular local area data communications network, originally developed 

by Xerox Corp., that accepts transmission from computers and terminals.    Ethernet 
operates on a 10/100 Mbps base transmission rate, using a shielded coaxial cable or 
over shielded twisted pair telephone wire. 

Fragmentation: 

When transmitting a packet over a network medium, sometimes the 

packet is broken into several segments, if the size of packet exceeds that allowed by 
the network medium. 

Fragmentation Threshold: 

The Fragmentation Threshold defines the number of 

bytes used for the fragmentation boundary for directed messages. The purpose of 
"Fragmentation Threshold" is to increase the transfer reliability thru cutting a MAC 
Service Data Unit (MSDU) into several MAC Protocol Data Units (MPDU) in smaller 
size. The RF transmission can not allow to transmit too big frame size due to the 
heavy interference caused by the big size of transmission frame. But if the frame size 
is too small, it will create the overhead during the transmission. 

Gateway:

 a device that interconnects networks with different, incompatible 

 

16

communication protocols. 

HEX: 

Hexadecimal, HEX, consists of numbers from 0 – 9 and letters from A – F. 

IEEE: 

The 

I

nstitute of 

E

lectrical and 

E

lectronics 

E

ngineers, which is the largest 

technical professional society that promotes the development and application of 
electrotechnology and allied sciences for the benefit of humanity, the advancement of 
the profession. The IEEE fosters the development of standards that often become 
national and international standards. 

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.

 

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 2.4GHz, in particular, is being made available worldwide. 

MAC Address: 

Media Access Control Address is a unique hex number assigned by 

the manufacturer to any Ethernet networking device, such as a network adapter, that 
allows the network to identify it at the hardware level. 

Multicasting: 

Sending data to a group of nodes instead of a single destination. 

Multiple Bridge 

– One of the additional AP operating modes offered by 54Mbps 

Access Point, which allows a group of APs that consists of two or more APs to 
connect two or more Ethernet networks or Ethernet enabled clients together. The way 
that multiple bridge setups is based on the topology of Ad-Hoc mode. 

Node:

 A network junction or connection point, typically a computer or workstation. 

Packet: 

A unit of data routed between an origin and a destination in a network. 

PLCP: 

Physical layer convergence protocol 

PPDU: 

PLCP protocol data unit 

Preamble Type: 

During transmission, the PSDU shall be appended to a PLCP 

preamble and header to create the PPDU. Two different preambles and headers are 
defined as the mandatory supported long preamble and header which interoperates 
with the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std 
802.11-1999, and an optional short preamble and header. At the receiver, the PLCP 
preamble and header are processed to aid in demodulation and delivery of the PSDU.   
The optional short preamble and header is intended for application where maximum 
throughput is desired and interoperability with legacy and non-short-preamble capable 
equipment is not consideration. That is, it is expected to be used only in networks of 
like equipment that can all handle the optional mode. (IEEE 802.11b standard) 

PSDU: 

PLCP service data unit 

Roaming: 

A LAN mobile user moves around an ESS and enjoys a continuous 

connection to an Infrastructure network.

end. An RS-232 signal sent from the transmitting station to the 

receiving station requesting permission to transmit. 

RTS Threshold: 

Transmitters contending for the medium may not be aware of each 

other. RTS/CTS mechanism can solve this “Hidden Node Problem”. If the packet size 
is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be 
enabled. 

SSID: 

Service Set Identifier, which is a unique name shared among all clients and 

nodes in a wireless network. The SSID must be identical for each clients and nodes in 
the wireless network. 

Subnet Mask: 

The method used for splitting IP networks into a series of sub-groups, 

or subnets. The mask is a binary pattern that is matched up with the IP address to turn 
part of the host ID address field into a field for subnets. 

TCP/IP: 

Transmission Control Protocol/ Internet Protocol. The basic communication 

language or protocol of the Internet. It can also be used as a communications protocol 
in a private network, i.e. intranet or internet. When you are set up with direct access to 
the Internet, your computer is provided with a copy of the TCP/IP program just as 
every other computer that you may send messages to or get information from also has 
a copy of TCP/IP. 

Throughput: 

The amount of data transferred successfully from one point to another 

in a given period of time. 

WEP: 

Wired Equivalent Privacy (WEP) is an encryption scheme used to protect 

wireless data communication. To enable the icon will prevent other stations without 
the same WEP key from linking with the AP. 

Wireless Bridge 

– One of the additional AP operating modes offered by 54mpbs 

Access Point, which allows a pair of APs to act as the bridge that connects two 
Ethernet networks or Ethernet enabled clients together.
