3Com 128-bit Dynamic Security Link Encryption. 3Com’s proprietary 128-bit

 

 

 

Dynamic Security Link is built into the access point and permits user-level

 

 

 

authentication. This option can be used only with local access point

 

 

 

authentication. Users must log in with username and password. (The access point

 

 

 

username and password database can support up to 1000 names.) Once the user

 

 

 

is authenticated, the access point dynamically creates a unique 128-encryption key

 

 

 

for the user for that session. Encryption keys are generated automatically and so

 

 

 

do not need to be supplied. To take advantage of this security setting, clients must

 

 

 

use a 3Com Wireless LAN PC Card (model 3CRWE62092A).

 

 

 

 

802.1x RADIUS

The IEEE 802.1x standard specifies a general method for the provision of

Support

port-based network access control. It provides an architecture framework for

 

 

 

User-RADIUS authentication through an authenticator such as a wireless access

 

 

 

point or a switch. The access point supports any RADIUS implementation

 

 

 

compliant with RFC 2865 and following standard EAP, RFC 2284, 2716, and 2548

 

 

 

protocols. This includes support for port-based network access control, which

 

 

 

permits standard security protocols such as EAP and RADIUS to provide centralized

 

 

 

user identification, authentication, dynamic key management, and accounting.

 

 

 

(The access point supports RADIUS Accounting per RFC2866: Username, Start

 

 

 

time, Stop time, and Packet input/output.)

 

 

 

3Com does not supply RADIUS software or configuration instructions other than

 

 

 

 

 

 

what is applicable for access point configuration. Refer to your system

 

 

 

 

 

 

 

 

 

administrator for additional third-party software and configuration information.

 

 

 

The access point supports any RADIUS server that complies with RFC 2865 and

 

 

 

follows standard EAP, RFC 2284, 2716, and 2548.

 

 

 

 

Using the Wireless

3Com provides a software utility to allow Windows clients to authenticate to the

802.1x Agent

Access Point 8000 using either EAP-MD5 or 3Com Serial Authentication. The

 

 

 

802.1x agent can be used with any vendor’s PC card, but to take advantage of

 

 

 

3Com’s Serial Authentication, it must be used with a 3Com Wireless LAN PC Card

 

 

 

(model 3CRWE62092A) that has been upgraded to the latest firmware. A copy of

 

 

 

the agent must be installed on each client computer

 

 

 

Use the 3Com CD to install the wireless 802.1x agent on systems running under,

 

 

 

Windows 98, Windows 98 SE, Windows ME, Windows NT 4.0 with Service Pack

 

 

 

6a, Windows 2000, or Windows XP. Systems running under Windows XP include

 

 

 

support for EAP-MD5 and EAP-TLS. On Windows XP, the 802.1x agent is only

 

 

 

required when using 3Com’s Serial Authentication.

Authentication and

Authentication is initiated by associating to the access point. Alternatively,

Login

authentication can be manually initiated by selecting Start from the 802.1x agent

 

 

 

menu. At login, the agent prompts for user name and password. The user name

 

 

 

and password must match the name and password maintained by the RADIUS

 

 

 

server.

 

 

 

When the agent is running, a status icon in the system tray monitors the

 

 

 

authentication process. The appearance of this icon changes to reflect the current

 

 

 

state of the authentication process. If the user hovers the mouse over the icon, a

 

 

 

tool tip also appears to indicate the current authentication status.

11 Mbps specifications

3Com 11 Mbps was a pivotal product in the evolution of networking technology, paving the way for wireless communications as we know them today. Introduced in the late 1990s, this wireless LAN (Local Area Network) product utilized the IEEE 802.11 standard, which defined the protocols for wireless networking. Operating at a maximum data rate of 11 megabits per second, it offered users a revolutionary means of connecting devices without the constraints of physical cabling.

One of the main features of the 3Com 11 Mbps solution was its simplicity and ease of installation. Unlike traditional wired networks that involved intricate setups of cabling and switches, 3Com facilitated a swift deployment process. Users could set up a wireless network in minutes, allowing organizations to enhance their productivity without extensive infrastructure.

The technology behind 3Com 11 Mbps was based on Direct Sequence Spread Spectrum (DSSS) modulation. This approach spread the signal over a wider frequency range, which improved resistance to interference from other devices. The 2.4 GHz frequency band used by this network supported compatibility with various devices, making it a flexible option for businesses and homes alike.

In terms of security, 3Com incorporated Wired Equivalent Privacy (WEP), which aimed to provide a level of data confidentiality comparable to that found in wired networks. However, WEP was later found to have vulnerabilities, leading to the development of more secure protocols like WPA (Wi-Fi Protected Access) and WPA2 in subsequent technologies.

Another characteristic that distinguished the 3Com 11 Mbps system was its ability to support multiple devices simultaneously. With the emergence of wireless laptops, printers, and other peripherals, a single access point could service several users without significant performance degradation.

Ultimately, the 3Com 11 Mbps was a significant stepping stone in the development of wireless technology. It showcased the potential of wireless networking and set the standard for future innovations. Although much faster and more secure wireless technologies have since emerged, the legacy of 3Com 11 Mbps resides in the fundamental advancements it brought to the realm of connectivity, making it easier and more accessible for users around the globe.
