Viewing Statistics

The statistics pages display various categories of operational and performance

 

statistics associated with the access point. The values do not update dynamically,

 

but you can update them at any time by refreshing the display.

 

■ RF Statistics—Displays performance data for the radio transmissions to and

 

from the access point. The statistics related to transmissions from the access

 

point are listed in the Transmitted table on the left. Statistics related to radio

 

signals received by the access point are listed in the Received table on the right.

 

The RF statistics include the following numbers:

 

■ unicast frames successfully transmitted and received

 

■ broadcast frames transmitted and received

 

■ multicast frames transmitted and received

 

■ encrypted frames transmitted and received

 

■ frames fragments transmitted and received

 

■ beacon frames transmitted and received

 

■ ACK frames transmitted in response to successfully received frames

 

■ frames transmitted with corresponding ACK frames successfully received

 

■ RTS frames successfully transmitted and received

 

■ frames for which no CTS frames were received in response to RTS frames

 

being sent

 

■ CTS frames received in response to an RTS

 

■ frames transmitted that did not have their corresponding ACK packets

 

successfully received

 

■ frames that were retransmitted

 

■ frames received with checksum error

 

■ duplicate frames received

 

■ frames received with the WEP subfield of the Frame Control field set to one

 

and the WEPOn value for the key mapped to the TA's MAC address;

 

indicates that the frame should not have been encrypted or that frame is

 

discarded because the receiving STA does not support the privacy option

 

■ frames received with the WEP subfield of the Frame Control field set to one

 

and the value of the ICV not matching the ICV value calculated for the

 

contents of the received frame

 

■ Ethernet Statistics—Displays performance data for the wired Ethernet traffic

 

to and from the access point. The statistics related to wired transmissions from

 

the access point are listed in the Transmitted table on the left. Statistics related

 

to Ethernet traffic received by the access point are listed in the Received table

 

on the right. The Ethernet statistics include the following numbers:

 

■ packets that higher-level protocols requested be transmitted to a

 

subnetwork unicast address, including those that were discarded or

 

not sent

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.
