wireless I wired network clients.

Ad-Hoc mode is also know as ‘point-to-point’ mode, and in this mode, wireless devices such as

computer or PDA will not be capable to establish wireless connection with more than one wireless

device, and is suitable for establishing a one-to-one wireless connection between two wireless devices.

Before you can connect to any wireless access point or device by infrastructure or Ad-Hoc mode, there

two things you must know:

a. Wireless device’s ‘SSID’ (Service Set IDentifier, someone will call it 'access point’s name’).

You can scan for the SSID of other wireless devices nearby, but if the SSID of the wireless

device you wish to connect is hidden, you must know exact SSID before you can establish

connection with it.

b. If the wireless device you wish to connect uses encryption, you must know its encryption

key.

Please launch Ralink setup utility and it will scan for wireless access points near by:

Scan results will be displayed here, please check if the wireless device (access point or another

computer) with the SSID you wish to connect is shown here.

Scan result includes 6 types of information, they are:

4.5 Glossary

1. What is the IEEE 802.11g standard?

802.11g is the new IEEE standard for high-speed wireless LAN communications that provides for

up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream

wireless LAN technology for the home, office and public networks.

802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a for

the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b.

The 802.11g standard requires backward compatibility with 802.11b.

The standard specifically calls for:

A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz frequency

band, known as the extended rate PHY (ERP). The ERP adds OFDM as a mandatory new

coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54 Mbps

(optional speeds). The ERP includes the modulation schemes found in 802.11b including CCK

for 11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps.

B. A protection mechanism called RTS/CTS that governs how 802.11g devices and 802.11b

devices interoperate.

2. What is the IEEE 802.11b standard?

The IEEE 802.11b Wireless LAN standard subcommittee, which formulates the standard

for the industry. The objective is to enable wireless LAN hardware from different

manufactures to communicate.

4 Activate a profile

What does IEEE 802.11 feature support?

The product supports the following IEEE 802.11 functions:

• CSMA/CA plus Acknowledge Protocol

• Multi-Channel Roaming

• Automatic Rate Selection

• RTS/CTS Feature

• Fragmentation

• Power Management

What is Ad-hoc?

An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN card, Connected

as an independent wireless LAN. Ad hoc wireless LAN is applicable at a departmental scale for a branch

or SOHO operation.

What is Infrastructure?

An integrated wireless and 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.

What is BSS ID?

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

the same BSS ID.

What is WEP?

WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as

described in the IEEE 802 .11 standard.

What is TKIP?

TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the

reuse of encryption keys. TKIP is involved in the IEEE 802.11 i WLAN security standard, and the

specification might be officially released by early 2003.

What is AES?

AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the highest

degree of security and authenticity for digital information, wherever and however communicated or stored,

while making more efficient use of hardware and/or software than previous encryption standards. It is

also included in IEEE 802.11 i standard. Compare with AES, TKIP is a temporary protocol for replacing

WEP security until manufacturers implement AES at the hardware level.

10. Can Wireless products support printer sharing?

Wireless products perform the same function as LAN products. Therefore, Wireless products can

work with Netware, Windows 2000, or other LAN operating systems to support printer or file

sharing.

11. Would the information be intercepted while transmitting on air?

WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence

Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side,

WLAN series offer the encryption function (WEP) to enhance security and Access Control. Users can

set it up depending upon their needs.

12. What is DSSS? What is FHSS? And what are their differences?

Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes frequency in a

pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to

maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration

impulse noise. 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 is, 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.

13. What is Spread Spectrum?

Spread Spectrum technology is a wideband radio frequency technique developed by the military for

use in reliable, secure, mission-critical communication systems. It is designed to trade off bandwidth

efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in

the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and

thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal

being broadcast. If a receiver is not tuned to the right frequency, a spread -spectrum signal looks like

background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and

Frequency Hopping Spread Spectrum (FHSS).

14. What is WMM?

Wi-Fi Multimedia (WMM), a group of features for wireless networks that improve the user experience

for audio, video and voice applications. WMM is based on a subset of the IEEE 802.11e WLAN QoS

draft standard. WMM adds prioritized capabilities to Wi-Fi networks and optimizes their performance

when multiple concurring

applications, each with different latency and throughput requirements, compete for network

resources. By using WMM, end-user satisfaction is maintained in a wider variety of environments

and traffic conditions. WMM makes it possible for home network users and enterprise network

managers to decide which data streams are most important and assign them a higher traffic

priority.

15. What is WMM Power Save?

WMM Power Save is a set of features for Wi-Fi networks that increase the efficiency and flexibility

of data transmission in order to conserve power. WMM Power Save has been optimized for mobile

devices running latency-sensitive applications such as voice, audio, or video, but can benefit any

Wi-Fi device. WMM Power Save uses mechanisms included in the IEEE 802.11e standard and is

an enhancement of IEEE

802.11 legacy power save. With WMM Power Save, the same amount of data can be transmitted

in a shorter time while allowing the Wi-Fi device to remain longer in a low-power “dozing” state.

16. What is Gl?

Gl stands for Guard Interval. It's a measure to protect wireless devices from crossinterference.

If there are two wireless devices using the same or near channel, and they are close enough,

radio interference will occur and reduce the radio resource usability.

17. What is STBC?

STBC stands for Space-Time Block Coding, which is a technique used to transfer multiple copies

of data by multiple antenna, to improve data transfer performance. By using multiple antennas, not

only data transfer rate is improved, but also the wireless stability.

18. What is WPS?

WPS stands for Wi-Fi Protected Setup. It provides a simple way to establish unencrypted or

encrypted connections between wireless clients and access point automatically. User can press a

software or hardware button to activate WPS function, and WPS-compatible wireless clients and

access point will establish connection by themselves. There are two types of WPS: PBC

(Push-Button Configuration) and PIN code.
