that network technicians configure and test according to the following suggestions. 1. Configure the antenna installation position This is the first step to achieve "non-leak" wireless access nodes. the wireless signal coverage is used to determine the location of the Access Node antenna. Do not place the antenna next to the window because the glass cannot block

used to set up a wireless network. In this way, network resources can be shared in a wireless mode with an existing wired architecture. Q3: Will WLAN interference or affect the operation of other devices? ANS: basically, the frequency band used by wireless networks is within the high frequency range of ISM 2.4GHz. It does not interfere with the electrical appliances used in daily life or office, because the frequency is quite different, in addition, the wireless network itself has 12 channels a

At the same time, using the CCA technology can automatically avoid channel interference and take full advantage of channel bundling.I'm interested in this dual-built antenna, so I took this guy apart and looked at the internal structure. 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'alt =" "src =" http://www.bkjia.com/uploads/allimg/131227/03

Emi--electro Magnetic interference Electromagnetic interferencedefinition: refers to the electromagnetic wave and electronic components after the action of the interference phenomenon.Category: There are two kinds of conduction interference and radiation interference. Conduction disturbance:is the coupling (interference) of a signal from one electrical network to another by means of a conductive medium.Radiated interference:Refers to the interference source through space to its signal coupling (

Medium-High Frequency electronic label, also mostly passive electronic label, must be in the range of the reader antenna radiation; ultra-high-frequency wireless microwave technology, can be active or passive, for the active, the reader's antenna radiatio

the radiation to the human body, the power of the wireless router is generally not great, so we must grasp the layout well, it is best to see each other between the wireless router and the wireless router, and avoid wall blocking between them as much as possible. In addition, the capacity is greatly affected by the interference of nearby electronic devices during use, therefore, when setting the placement of a wireless router, you must stay away from the microwave oven, refrigerator, and other

Solution report Question Portal Question: In the matrix of H × w, O indicates the space, * indicates the city, and wireless devices can only be mounted to the city. How many devices are required to cover the city. Each device can only cover two adjacent devices. Ideas: It seems that the greatest matching is direct. Finding the maximum number of matching pairs, plus cities without matching, is the answer. After reading the question on the Internet, the correct solution is the minimum path coverag

Homeopathic indicators (CCI) 1. indicator descriptionCCI (commodity channel Lndex) Chinese name: homeopathic indicatorThis indicator was created by donaldlambert to specifically measure whether the stock price has exceeded the normal distribution range. This is a special type of overbought and oversold indicators, which fluctuates between positive infinity and negative infinity. However, it is not necessary to take 0 as the central axis. This is also different from the indicator that fluctuates

wireless network will lead to "Service Unavailable" or "springboard" for attacking other networks. To minimize the risk posed by security vulnerabilities, ensure that network technicians are configured and tested with the following recommendations. 1, plan the antenna installation location This is the first step in implementing a "non-leaking" wireless access node, and the location of the antenna is de

products after-sales service personnel also have no good way to solve, but is repeatedly told the user to upgrade the software version to the latest, or simply said that the hardware design problems. Short effective distance The problem has become so common that the actual effective distance of a wireless product can reach its claimed maximum distance of 1/3~1/2 even if it's not bad. The emergence of this problem has many factors, such as the effectiveness of wireless

With the rapid development of mobile communication, it becomes more and more important to solve the problem of indoor cover and capacity, and the micro-cell base station becomes an important means to improve the indoor coverage effect and to increase the special area capacity. The importance of 3G indoor coverage Good network coverage, especially indoor coverage is the key to the success of 3G, NTT DoCoMo is a good example: NTT DoCoMo found that the user's indoor usage accounted for 70%, and o

Take off the screen as shown below (note that this figure I did not remove the high-pressure bar, not the correct method of disassembly): The white screws on the motherboard are all removed. A black screw in the lower right corner of the image is also to be torn down. The black screws near the USB port do not have to be torn down. See th

network has no signal Fault analysis There are several possible causes for this failure: (1) wireless network card distance from the wireless AP or wireless router is too far, more than the coverage of wireless networks, wireless signal to reach the wireless network card has been very weak, so that wireless clients can not be normal connection. (2) The wireless AP or wireless router does not power up or does not work properly, causing the wireless client to not connect at all. (3) When the
