TLS

Transport Layer Security. A type of authentication method using the

 

Extensible Authentication Protocol (EAP) and a security protocol called the

 

Transport Layer Security (TLS). EAP-TLS uses certificates which use

 

passwords. EAP-TLS authentication supports dynamic WEP key

 

management. The TLS protocol is intended to secure and authenticate

 

communications across a public network through data encryption. The TLS

 

Handshake Protocol allows the server and client to provide mutual

 

authentication and to negotiate an encryption algorithm and cryptographic

 

keys before data is transmitted.

TTLS

Tunneled Transport Layer Security. These settings define the protocol and

 

the credentials used to authenticate a user. In TTLS, the client uses EAP-

 

TLS to validate the server and create a TLS-encrypted channel between

 

the client and server. The client can use another authentication protocol,

 

typically password-based protocols, such as MD5 Challenge over this

 

encrypted channel to enable server validation. The challenge and response

 

packets are sent over a non-exposed TLS encrypted channel. TTLS

 

implementations today support all methods defined by EAP, as well as

 

several older methods (CHAP, PAP, MS-CHAP and MS-CHAPv2). TTLS can

 

easily be extended to work with new protocols by defining new attributes

 

to support new protocols.

WEP

Wired Equivalent Privacy. Wired Equivalent Privacy, 64- and 128-bit (64-

 

bit is sometimes referred to as 40-bit). This is a low-level encryption

 

technique designed to give the user about the same amount of privacy

 

that he would expect from a LAN. WEP is a security protocol for wireless

 

local area networks (WLANs) defined in the 802.11b standard. WEP is

 

designed to provide the same level of security as that of a wired LAN. WEP

 

aims to provide security by data over radio waves so that it is protected as

 

it is transmitted from one end point to another.

WEP Key

Either a pass phrase or hexadecimal key.

 

The pass phrase must be 5 ASCII characters for 64-bit WEP or 13 ASCII

 

characters for 128-bit WEP. For pass phrases, 0-9, a-z, A-Z, and ~!@#$%

 

^&*()_+`-={}[]\:";'<>?,./ are all valid characters.

 

The hex key must be 10 hexadecimal characters (0-9, A-F) for 64-bit WEP

 

or 26 hexadecimal characters (0-9, A-F) for 128-bit WEP.

Wi-Fi

Wireless Fidelity. Is meant to be used generically when referring of any

 

type to 802.11 network, whether 802.11b, 802.11a, or dual-band.

Wireless

A stand-alone wireless hub that allows any computer that has a wireless

Router

network adapter to communicate with another computer and to connect to

 

the Internet. Also known as an access point.

WLAN

Wireless Local-Area Network. A type of local-area network that uses high-

 

frequency radio waves rather than wires to communicate between nodes.

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.
