Wireless Networks all know that mobile communication, wireless Internet access, and wireless LAN are all part of wireless networks, but many friends cannot distinguish them. The following section summarizes the basic knowledge of wireless networks.
Basic knowledge of wireless networks 1: What is WLAN? What is the most popular wireless networking technology?
WLAN is short for Wireless LAN, that is, Wireless LAN. Wireless LAN uses wireless technology to achieve fast Ethernet access. Looking at the

It may take some time for the full IEEE 802.11i standard to be launched, and the Wi-Fi Alliance wants to enable the new security standard to be deployed as soon as possible to eliminate users'Wireless NetworkSecurity concerns allow the wireless network market to expand quickly. Therefore, the draft of the fifth draft of the IEEE 802.11i (

In addition to the frequency bands, the IEEE 802.11A adopts an imp

Regarding the wireless internet is not smooth, the wireless network connection is not good question, this article has summed up many for everybody, and has provided the concrete breakdown description, the solution and so on. Hope that through this article, can make everyone convenient, simple to solve their own computer wireless fault.

From the application requirements, the wireless network is very suitable for schools of some sites that are not easy to network wiring applications. Now most of the campus has wired LAN, how to further expand the original network, so that every corner of the campus in the network, the formation of a true sense of the campus network? This article is to introduce how to use Wireless LAN technology to form a campus network.

1. Work Summary
Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future increase in transmission rate, cable and conn
that the data rate is higher, the security is better and the quality of service is more and more guaranteed.
And from the wireless LAN standards of the supporters and the geographical scope of use, wireless LAN can be said to have three camps: IEEE 802.11 series of standards, European hiperlan1/hiperlan2 and Japan's MMAC series standards.
802.11 series Standard
In the 802.11 series, there are 4 standards involving the physical layer: 802.11, 802.1
histogram [14] feature (census transform histogram, centrist for short), a distinctive texture structure feature is proposed, unlike the centrist histogram, which is similar to a Local Binary Pattern histogram, the feature integrates the laws of human visual psychology to better detect pedestrians in road environments such as illumination fluctuations and background clutter.

Since we mentioned diskless at the beginning, today is also a very important thing related to diskless, that is, Nic parameter settings. We all know that diskless means that the client does not have a hard disk, and diskless means to put the client's hard disk on the server and work throug
In terms of application requirements, wireless networks are suitable for some campus applications that are not easy to use for network cabling. Currently, most campuses have wired LAN. How can we further expand the original network so that every corner of the campus is on the network to form a campus network in the true sense? This article describes how to use the wireless LAN technology to build a campus network.

on the 6509 gateway 172.25.6.210, the problem arises, with small packet ping, basically no delay, but with a large packet ( Close to 18024b,cisco supported maximum packets) there was a drop in the ping when the problem was definitely here.
(5) To re-examine the configuration of Annette and 6509 and NAT servers, we found a problem: the command to configure VLAN6 and VLAN7 on Annette and add the corresponding ports to the VLAN is: Add VLAN 6 ports=23 frame=untagged ( Add Port 23rd to the VLAN6,
