Ad Hoc QoS Mode

Quality of Service (QoS) control in ad hoc networks. QoS provides prioritization of

 

traffic from the access point over a wireless LAN based on traffic classification. WMM

 

(Wifi MultiMedia) is the QoS certification of the Wi-Fi Alliance (WFA). When WMM is

 

enabled, the adapter uses WMM to support priority tagging and queuing capabilities for

 

Wi-Fi networks.

 

WMM Enabled.(Default)

 

WMM Disabled

 

NOTE: This setting is unavailable if the adapter is an Intel PRO/Wireless 3945BG

 

Network Connection, Intel PRO/Wireless 2915ABG Network Connection or an Intel PRO/

 

Wireless 2200BG Network Connection.

Mixed mode protection

Use to avoid data collisions in a mixed 802.11b and 802.11g environment. Request to

 

Send/Clear to Send (RTS/CTS) should be used in an environment where clients may not

 

hear each other. CTS-to-self can be used to gain more throughput in an environment

 

where clients are in close proximity and can hear each other.

Preamble Mode

Changes the preamble length setting received by the access point during an initial

 

connection. Always use a long preamble length to connect to an access point. Auto Tx

 

Preamble allows automatic preamble detection. If supported, short preamble should be

 

used. If not, use long preamble (Long Tx Preamble).

 

NOTE: This setting is unavailable if the adapter is an Intel PRO/Wireless 3945ABG

 

Network Connection.

Preferred Band

Select the operating band. The selections are:

 

802.11g

 

802.11a

 

802.11b

 

NOTE: This setting is unavailable if the adapter is an Intel PRO/Wireless 3945ABG

 

Network Connection or Intel PRO/Wireless 2200BG Network Connection.

Roaming Aggressiveness

This setting allows you to define how aggressively your wireless client roams to improve

 

connection to an access point.

 

Default: Balanced setting between not roaming and performance.

 

Lowest: Your wireless client will not roam. Only significant link quality

 

 

degradation causes it to roam to another access point.

Throughput Enhancement

Changes the value of the Packet Burst Control.

 

Enable: Select to enable throughput enhancement.

 

Disable: (Default) Select to disable throughput enhancement.

Transmit Power

Default Setting: Highest power setting

 

Lowest Minimum Coverage: Set the adapter to a lowest transmit power. Enable you

to expand the number of coverage areas or confine a coverage area. Reduce the coverage area in high traffic areas to improve overall transmission quality and avoid congestion and interference with other devices.

Highest Maximum Coverage: Set the adapter to a maximum transmit power level. Select for maximum performance and range in environments with limited additional radio devices.

NOTE: The optimal setting is for a user to always set the transmit power at the lowest possible level still compatible with the quality of their communication. This allows the maximum number of wireless devices to operate in dense areas and reduce interference with other devices that this radio shares radio spectrum with.

3945ABG specifications

The Intel 3945ABG is a wireless networking adapter that played a significant role in advancing wireless connectivity in laptops and portable devices. Introduced in the mid-2000s, this adapter is notable for its dual-band capabilities and compliance with the IEEE 802.11 a/b/g standards. It supports both 2.4 GHz and 5 GHz frequency bands, enabling users to connect to a variety of wireless networks while offering improved performance and flexibility.

One of the standout features of the Intel 3945ABG is its support for MIMO technology, which stands for Multiple Input Multiple Output. This innovative technology enhances data transmission rates and increases the range of wireless connections by utilizing multiple antennas for sending and receiving data. MIMO allows the adapter to operate more efficiently in environments with obstacles, such as walls or furniture, making it an ideal choice for users who need reliable connectivity in varied settings.

The Intel 3945ABG adapter also includes Wi-Fi Protected Access (WPA) and WPA2 security protocols, ensuring that data transmitted over the wireless network remains secure. This is especially important in a time when wireless networks became progressively more vulnerable to unauthorized access and data breaches. The adapter's compatibility with these security standards aids users in establishing secure communications, whether for casual web browsing or sensitive tasks.

In terms of performance, the Intel 3945ABG offers maximum theoretical speeds of up to 54 Mbps in the 802.11a and 802.11g modes, while maintaining lower speeds in the 802.11b mode (up to 11 Mbps). In practical use, this means that users can achieve high data transfer rates in optimal conditions, making it suitable for video streaming, online gaming, and large file downloads.

The Intel 3945ABG also integrates seamlessly with Intel's Centrino mobile technology, which enhances power efficiency and optimizes the overall performance of a laptop. This synergy not only extends battery life but also provides a smooth user experience, as it allows the adapter to effectively manage network resources and maintain a stable connection.

In summary, the Intel 3945ABG wireless adapter is characterized by its dual-band support, MIMO technology, robust security features, and integration with Intel's Centrino technology. While it may now be considered outdated by modern standards, it served as an important stepping stone in the evolution of wireless networking technology and continues to be remembered for its contributions to mobile connectivity.
