28CHAPTER 4: CONFIGURING THE ACCESS POINT 8000

be set to Diversity Off. Generally, if the access point is using the standard detachable antennas, this parameter should be set to Diversity On to maximize the transmission and reception qualities of using both antennas.

■ Transmit Power—You can adjust the transmit power between these settings:

 

 

 

High: +18 dBm at the connector

 

 

 

Medium: +13 dBm at the connector

 

 

 

Low: +7 dBm at the connector

 

 

 

These settings may need to be adjusted for compatibility with different types of

 

 

 

external antennas that have different gains. These adjustments may be

 

 

 

required to be legally compliant with the communications regulations in certain

 

 

 

countries. For example, if you are using a high-gain antenna such as the

 

 

 

optional flat-panel directional antenna (model 3CWE498) in the United States,

 

 

 

Canada, Mexico, Argentina, Brazil, Taiwan, Malaysia, New Zealand, Colombia,

 

 

 

India, and Peru, no transmit power restrictions apply. If you are using it in any

 

 

 

other country, however, you must manually select Low or Medium power.

 

 

 

 

Setting Advanced

The Advanced Settings page provides additional features for controlling

Data Transmission

client access and communications among clients.

Properties

 

 

Changing the advanced settings causes the access point to reassociate

 

 

 

 

 

 

 

 

 

with clients, which can temporarily disrupt their network operations.

 

 

 

 

 

 

 

■ Load Balancing—Allows you to specify the maximum number of clients that

 

 

 

can associate with the access point at the same time. To specify a number, click

 

 

 

On, enter a number between 1 and 256, and click Save. To disable load

 

 

 

balancing, click Off. When load balancing is Off (the default) up to 256 clients

 

 

 

can associate with the access point. If you specify a small number of clients, it is

 

 

 

recommended that you also choose the shortest possible time in the Client List

 

 

 

Timeout setting.

 

■ Client-to-ClientBlocking—When this setting is On, clients associating with

 

 

 

the access point are prevented from communicating with one another,

 

 

 

providing client privacy in public access situations. When this setting is Off,

 

 

 

clients associating with the access point can communicate.

 

■ Client List Timeout—This setting determines the length of time a client

 

 

 

remains in the access point’s list of associated clients after ending the

 

 

 

association. You can choose a timeout setting from the list. It is recommended

 

 

 

that you choose the shortest possible timeout setting, especially if you have

 

 

 

specified a small number of clients in the Load Balancing setting.

 

■ Broadcast WLAN Service Area Name (ESSID)—When this mode is enabled

 

 

 

(the default mode), the access point WLAN service area is visible to

 

 

 

wireless clients.

 

 

 

When this mode is disabled, the access point WLAN service area is invisible to

 

 

 

wireless clients. Clients that support association with access points in privacy

 

 

 

mode can associate with the access point by specifying the access point’s

 

 

 

Wireless LAN Service Area.

 

 

 

Click On to enable broadcasting. Click Off to disable broadcasting.

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.
