The multiple input multiple output (Multiple-input, Multiple-output;mimo) technology provides an excellent way to extend the range of the Wireless area Network (WLAN), and has recently become the focus. MIMO technology began in 1985, but only now applies to wafer-level devices to dramatically improve transmission range and capacity. Since MIMO is not a single concept, but consists of a variety of wireless RF technology, so we must fully understand th

Many enterprises have encountered wireless network capacity problems. As wireless devices and high-bandwidth applications surge, network speed and data capacity become increasingly difficult to guarantee. To meet the increasing demand, the WLAN administrator should make two preparations: improve the efficiency of the existing channel and transfer the bandwidth load by deploying a new frequency. These two strategies are expected to help enterprises clo

With the development of the mobile Internet and the popularization of smart terminals, data service traffic has experienced explosive growth. To meet users' bandwidth requirements for wireless networks, telecom operators usually use multiple access methods to achieve convenient access and smoother user experience. The deployment of multiple access methods may result in multiple network standards due to the characteristics of the network standard and different coverage. In complex multi-access sc

After the emergence of WLAN technology, "security" has always been a shadow around the word "wireless". Attacks and cracking against security authentication and encryption protocols involved in wireless network technology have emerged. Currently, there may be hundreds or even thousands of articles on how to attack and crack WEP on the Internet, but how many people can truly break WEP's encryption algorithm? Next I will introduce some knowledge about W

protective time slot (neither launch nor receive), or in the uplink time slot. Therefore, when the parameters of the base station are reasonably configured, the two systems will not interfere with each other if the upper and lower time slots are not staggered. Is there mutual interference between the TD-LTE and the current WLAN system when the adjacent frequency coexist? How can this problem be solved? A: The TD-LTE indoor base station or room system

1. Introduction WLAN is short for Wireless LAN, that is, Wireless LAN. The so-called wireless network, as its name implies, is an information network composed of radio waves as transmission media. As WLAN products do not need to lay communication cables, they can flexibly cope with the changing settings of various network environments. WIAN technology provides users with better mobility, flexibility, and s

WLANIt is no longer just a simple network access method. Many important applications of enterprises, such as voice, video, and location services, are gradually deployed on wireless networks. Even for normal network access, users also hope that the higher the bandwidth, the better. As applications increase,Wireless InterferenceThe impact of problems on the Quality of network services is becoming increasingly prominent. Wireless Interference detection Large-scale

The development of wireless LAN technology is very mature. To improve the security of our wireless LAN, we need to start from many aspects. WLAN technology provides users with better mobility, flexibility, and scalability, and provides fast and cost-effective LAN access in areas that are difficult to re-wiring, wireless Bridges can be used to provide LAN access for remote sites and users. However, when users' expectations for

Wireless jamming can be divided into WLAN interference and non-WLAN interference by type. WLAN interference refers to the interference source to send the RF signal also meet the 802.11 standard, in addition to the non-WLAN interference. The interference of WLAN can be divide

The development of WLAN technology is already making our lives more convenient. How can we set up WLAN Access Points controlled by wireless LAN switches? This article introduces you. Do you want to achieve a signal without interference and a stable wireless network connection? WLAN wireless LAN switches can be configured to fully control wireless access points. H

In enterprises, the function of a wireless LAN switch is very powerful. For more information about the function of the switch in the network, see "network traffic police"-a wireless LAN switch.) here, let's take a look at how to use a wireless LAN switch to Efficiently build a wireless network. A wireless LAN switch can connect to a WLAN Access Point (AP) through a wired connection (with a switch port ). They can also connect to the enterprise network

At present, wireless interference is the biggest impact on the wireless network, which seriously affects the stability and transmission speed of the wireless network. It is widely used in daily life, wireless Network interference also occurs constantly. 1. Large WLAN networks generally adopt a thin AP architecture. The detection and reduction of wireless interference can be performed by scanning the AP that provides access services, or by a network co
