4.5.3 Channel

Wireless Settings -> Channel

The channel is the frequency range used by radio. In 802.11g/b standard, there are

maximum of 14 Channels. However, the available channels in each country are

dependant on the local regulation. If you are living in Europe, you can use channel 1 to 13.

If you are living in the United States, you can use channel 1 to 11.

Each wireless channel takes between 22 to 25MHz of frequency width. But the channels

are only 5MHz apart. Therefore, only every 5 channels can be free of interference with

each other. It is recommended that you can do a site survey to find about what channels

are used by surrounding AP and choose a channel that is not used by other APs.

4.5.4 Wireless Security

Wireless Settings -> Wireless Security

You should set up the wireless security immediately to ensure the security of your data

transmission and to prevent the unauthorized access. The easiest way to setup encryption

is to use the “Setup Wizard”. It automatically chooses the most secured and easiest

scheme for your wireless security settings. However, if you wish to choose your own

encryption scheme, the Air3G offers various type of encryption including WEP, WPA-PSK,

WPA, WPA2, WPA2-PSK encryptions method. In general, the WPA-PSK and WPA2-PSK

are the most popular and secured encryption scheme.

4. Configuration: 3G Router Mode

41 AirLive Air3G User’s Manual

Procedure to make encryption

 Step1: Select your SSID: If you have enabled the “Multiple SSID” function, there will

be more than one SSID to choose from. Each SSID(Virtual AP) can have its own

security policy.

 Step2: Select Security Policy: Air3G offers a full suite of security policy including

WEP(Pre-Shared Key), WPA(certificate), WPA-PSK(AES), WPA2-PSK(AES), and

802.1x Radius Authentication. Recently WiFi regulation prevent the use of TKIP

encryption in 11n mode. Therefore, the TKIP is only available in 11b/g mode. We

highly recommend using WPA2-PSK AES Encryption as the easiest and very

secured scheme for encryption.

 Guard Interval: Guard interval is placed at the beginning of each transmission. It is

used to reduce the interference effect of multi-path transmissions. The use of long

Guard Interval may perform better in interference or multipath environment. However,

it can reduce the performance.

 MCS (Modulation and Code Scheme): MCS level for the 11n mode. It is

recommended to leave it at Auto.

AirLive Air3G User’s Manual 44

 Decline BA Request: Enable this option to decline the Block ACK requests by other

devices.

 BG Protection: The 802.11g standard includes a protection mechanism to ensure

mixed 802.11b and 802.11g operation. If there is no such kind of mechanism exists,

the two kinds of standards may mutually interfere and decrease network’s

performance..

 Beacon Interval: The device broadcasts beacon frames regularly to announce its

existence. The beacon Interval specifies how often beacon frames are transmitted in

time unit of milliseconds. The default value is 100, and a valid value should be between

1 and 65,535.

 Fragmentation: When the size of a unicast frame exceeds the fragmentation

threshold, it will be fragmented before the transmission. It should have a value of

256-2346 bytes, with a default of 2346. If you experience a high packet error rate,

you should slightly decrease the Fragmentation Threshold.

 RTS Threshold: RTS/CTS frames are used to gain control of the medium for

transmission. Any unicast (data or control) frames larger than specified RTS threshold

4. Configuration: 3G Router Mode

45 AirLive Air3G User’s Manual

must be transmitted following the RTS/CTS handshake exchange mechanism. The

RTS threshold should have a value between 256-2347 bytes, with a default of 2347. It

is recommended that this value does not deviate from the default too much.

 Short Preamble: A preamble is a signal used in wireless environment to synchronize

the transmitting timing including Synchronization and Start frame delimiter. In a "noisy"

network environment, the Preamble Type should be set to Long Preamble. The Short

Preamble is intended for applications where minimum overhead and maximum

performance is desired. If in a "noisy" network environment, the performance will be

decreased.

 Tx Burst and Packet Aggregate: These are the scheme used for improving the

performance of the data transmission in 11n and Turbo modes. It is recommended to

keep the settings on.

 AckTimeOut: When a packet is sent out from one wireless station to the other, it will

waits for an Acknowledgement frame from the remote station. The station will only

wait for a certain amount of time, this time is called the ACK timeout. In most

conditions, please do not change the Tx and Rx Acktimeout value. The Air3G’s

default value is correct in most case.s.

4.5.9 WMM Settings

Wireless Settings -> WMM Settings

Wi-Fi Multimedia (WMM) is a standard to prioritize traffic for multimedia applications. The

WMM Settings is to specify parameters on multiple data queue for better performance of

differentiated wireless traffic like Voice-over-IP (VoIP), other types of audio, video, and

streaming media as well as traditional IP data over the AP.

Configure the WMM QoS Parameters

4. Configuration: 3G Router Mode

AirLive Air3G User’s Manual 46

 AC Type

The queue and associated priorities and parameters for transmission are as follows:

 Data 0 (Best Effort, BE): Medium priority queue, medium throughput anddel ay.

Most traditional IP data is sent to this queue.

 Data 1 (Background, BK): Lowest priority queue, high throughput. Bulk data

that requires maximum throughput and is not time-sensitive is sent to this queue

(FTP data, for example):

 Data 2 (Video, VI): High priority queue, minimum delay. Time-sensitive data

such as Video and other streaming media are automatically sent to this queue.

 Data 3 (Voice, VO): Highest priority queue, minimum delay. Time-sensitive

data such as Voice over IP (VoIP) is automatically sent to this queue.

Packets in a higher priority queue will be transmitted before packets in a lower

priority queue.

 ECWmin and ECWmax

If an access point detects that the medium is in use, it uses the DCF random backoff

timer to determine the amount of time to wait before attempting to access a given

channel again. Each access point waits some random period of time between retries.

The wait time (initially a random value within a range specified as the Minimum

4. Configuration: 3G Router Mode

47 AirLive Air3G User’s Manual

Contention Window increases exponentially up to a specified limit Maximum

Contention Window.

The random delay avoids most of the collisions that would occur if multiple APs got

access to the medium at the same time and tried to transmit data simultaneously. The

more active users you have on a network, the more significant the performance gains

of the backoff timer will be in reducing the number of collisions and retransmissions.

The random backoff used by the access point is a configurable parameter. To describe

the random delay, a "Minimum Contention Window" (ECWMin) and a "Maximum

Contention Window" (ECWMax) is defined.

 ECWmin: The value specified for the Minimum Contention Window is the

upper limit of a range for the initial random backoff wait time. The number used

in the random backoff is initially a random number between 0 and the number

defined for the Minimum Contention Window.

 ECWmax: If the first random backoff time ends before successful

transmission of the data frame, the access point increments a retry counter, and

doubles the value of the random backoff window. The value specified in the

Maximum Contention Window is the upper limit for this doubling of the random

backoff. This doubling continues until either the data frame is sent or the

Maximum Contention Window size is reached.

 AIFS

The Arbitration Inter-Frame Spacing (AIFs) specifies a wait time (in milliseconds) for

data frames. 802.11e uses interframe spaces to regulate which frames get access to

available channels and to coordinate wait times for transmission of different types of

data. The AIFs ensures that multiple access points do not try sending data at the same

time but instead wait until a channel is free. Valid values for AIFs are 1 through 255.

 Transmission Opportunity

The Transmission Opportunity (TXOP) is an interval of time when a WMM client station

has the right to initiate transmissions onto the wireless medium. This value specifies

(in milliseconds) the Transmission Opportunity (TXOP) for client stations; that is, the

interval of time when a WMM client station has the right to initiate transmissions on the

wireless network.

We recommend that you use the default settings on the WMM QoS

page. Changing these values can lead to unexpected blockages of

traffic on your wireless LAN, and the blockages might be difficult to

diagnose.

5.6 Firmware Upgrade

System Configuration -> Firmware Upgrade

You can upgrade the firmware of your Air3G (the software that controls your Air3G’s

operation). Normally, this is done when a new version of firmware offers new features that

you want, or solves problems that you have encountered with the current version.

 Upgrade Firmware:

To update the Air3G firmware, first download the firmware from AirLive web site to your

local disk. Then from the above screen enter the path and filename of the firmware

file (or click Browse to locate the firmware file). Next, Click the Apply button to start.

The new firmware will be loaded to your Air3G. After a message appears telling you that the

operation is completed, you need to reset the system to have the new firmware take effect.
