power of the wireless router is generally small, so the use of the process is very much in the vicinity of electronic equipment interference, so in the setting of wireless router placement, we must remember to stay away from microwave ovens, refrigerators and other household appliances. A good antenna is also to ensure that the router wireless transmission distance and stability of the effective guarantee that some high-end wireless routers will us

The antenna-fed system refers to electromagnetic waves radiating from the antennas to the surrounding space. Electromagnetic waves consist of electric fields and magnetic fields. It is stipulated that the direction of the electric field is the direction of the antenna polarization. The antennas commonly used are mono-polarized. The antenna and feeder systems are

outdoor orientation or omnidirectional antenna. For wireless network interconnection of remote outdoor sites, the high-gain outdoor orientation or omnidirectional antenna must be used together to achieve point-to-point connection, omnidirectional antennas support point-to-point connections ｡ 3. lightning arresters. In order to ensure the normal operation of the wireless network system during thunderstorms,

network speeds will naturally slow down. In this case, you can use software (such as WirelessMon) to check which channels are used by nearby hotspots, remember the channels that are least occupied, and enter the Web Settings interface of the wireless router, manually adjust the channel of the wireless router to improve the wireless experience. Of course, if your wireless router supports the 5 GHz band and your terminal equipment also supports it, then you can enjoy the "highway" on your own! 4.

), The LB2211-E1) fixed on the rod, and tighten the nut to prevent sliding. 2, the high frequency feeder 7) one end connected to the antenna port, the other end connected to the LB2211-E1) N-type seat if needed, please connect Lightning Arrester), and tighten, 6) wrap the metal part. Adjust the angle of the antenna so that the antennas at both ends are opposite and keep the same line as far as possible. 3.

I. RCS definitionany electromagnetic waves with a definite polarization are exposed to the target, which can cause refraction or scattering in all directions. The scattering wave is divided into two parts: one is composed of the scattering wave with the same polarization as the receiving antenna, and the two is the different change of the scattering wave, and the receiving antenna is not responding. These t

replacing the wireless network adapter card. In general, laptop wireless network adapter cards are installed through the slot, and most of the only need to remove the bezel on the back of the laptop computer can be directly replaced. Therefore, simply remove the old card, install the new card, and update the device driver. However, in the course of the replacement, special attention needs to be paid to the antenna of the wireless network adapter card

, wireless network transmission distance is limited, although the general wireless router nominal transmission distance can reach 100-300 meters, but in the actual use if there is a barrier, this distance will be shortened dramatically and will lead to slow data transmission speed. Third, slow speed solution Wireless router and network card matching is to enhance the speed of wireless data transmission is an important factor, we know that the current market on the wireless transmission standar

HSDPA (High speed downlink packet access) is used to realize high speed downlink data service of WCDMA network, which can make the downlink data rate reach 8~10mbps, which is regarded as the main solution of the 3G era. The data rate can reach 20Mbps in the HSDPA system with multiple and multiple out (MIMO) technology. The emergence of HSDPA has aroused great concern of the industry. As the following evolution technology of WCDMA system, many key technologies in HSDPA are similar to CDMA20001XEV

The development and prosperity of wireless networks are inseparable from the construction of networks. However, problems such as poor planning or adaptability to the current environment may also occur during the construction process. Then we need to optimize the network. Next we will introduce the optimization of CDMA wireless networks. The CDMA system needs to be gradually expanded and optimized during the operation process, and most of the problems in the mobile communication network are unpre

Source: CCID In most cases, frequent wireless connection disconnection is caused by improper use. It is usually manifested in faults such as weak wireless signal, difficult connection, slow communication speed, and disconnection. The reason is generally caused by the following factors. 1. Human Factors The distance between the wireless router and the network card is too long. In this case, you can only configure an appropriate antenna. There are obsta

port of the wireless routing product. For network products in long-term working conditions, the advantages and disadvantages of the Heat Dissipation Capacity will directly affect the product stability and service life, so by carefully observing the shell material, heat sink port and volume, we will probably get some information about the product's heat dissipation performance. Of course, this is also one of the best methods to detect wireless routing products before purchase. 3. view the

Day-feed coverage, as the name implies is the use of AP, feeder, plus ceiling antenna to build wireless network. thereby reducing the use of APS to reduce the interference of the same frequency.Working principle:Day-feed coverage using APS are high-power industrial wireless APs, power is the general home wireless router 7-8 times, is the general ceiling-type AP 5-6 times, high-power is to ensure the basic coverage effect. The greater the power, the be

two. In addition, a lot of home appliances in the work of the wireless network will also cause electromagnetic interference, so the placement of wireless routers should also try to stay away from these appliances. 　Third, extended antenna enhancement signal Because the size of the antenna gain directly affects the signal emission intensity and the ability to receive, and some of the routers

network. For this reason, before placing wireless internet nodes or wireless router devices, we should make a rough estimate of the number of users of wireless Internet access, and ensure that many wireless internet users can be evenly connected to different wireless access devices. Make sure each one of them is able to surf the internet efficiently and wirelessly. focus on the antenna position under normal circumstances, wireless internet nodes
