EAP-GTC

The EAP-GTC (Generic Token Card) is similar to the EAP-OTP except with

 

hardware token cards. The request contains a displayable message, and

 

the response contains the string read from the hardware token card.

EAP-OTP

EAP-OTP (One-Time Password) is similar to MD5, except it uses the OTP as

 

the response. The request contains a displayable message. The OTP

 

method is defined in RFC 2289. The OTP mechanism is employed

 

extensively in VPN and PPP scenarios but not in the wireless world

EAP-SIM

Extensible Authentication Protocol-Subscriber Identity Module (EAP-SIM)

 

authentication can be used with:

Network Authentication types: Open, Shared, and WPA-Enterprise, WPA2-Enterprise.

Data Encryption types: None, WEP and CKIP.

 

A SIM card is a special smart card that is used by GSM-based digital

 

cellular networks. The SIM card is used to validate your credentials with

 

the network

EAP-TLS

A type of authentication method using EAP and a security protocol called

 

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

 

passwords. EAP-TLS authentication supports dynamic WEP key

 

management.

EAP-TTLS

A type of authentication method using EAP and Tunneled Transport Layer

 

Security (TTLS). EAP-TTLS uses a combination of certificates and another

 

security method such as passwords.

Encryption

FHSS

File and printer sharing

Fragmentation threshold

Scrambling data so that only the authorized recipient can read it. Usually a key is needed to interpret the data.

Frequency-Hop Spread Spectrum. Technology used in radio transmission. Incompatible with DSSS.

A capability that allows a number of people to view, modify, and print the same file(s) from different computers.

The threshold at which the wireless adapter breaks the packet into multiple frames. This determines the packet size and affects the throughput of the transmission.

GHz

Gigahertz. A unit of frequency equal to 1,000,000,000 cycles per second.

Host computer The computer that is directly connected to the Internet via a modem or network adapter.

Infrastructure

A wireless network centered around an access point. In this environment,

Network

the access point not only provides communication with the wired network,

 

but also mediates wireless network traffic in the immediate neighborhood.

IEEE

Institute of Electrical and Electronics Engineers (IEEE) is an organization

 

involved in defining computing and communications standards.

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.
