wireless network will also cause electromagnetic interference, so the placement of wireless routers should also try to stay away from these appliances. 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 in the market are removable design, so the wireless router to replace a high gain

other signal channels more than 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

Advantages: good security and anti-counterfeiting performance; can be used on books, CDs, and tapes; fast read/write speed without interference; can be read at the same time; applicable: various media books, tapes, and CDs); 2. intelligent Security Detection System 1) function description checks whether any missing books are taken out, and provides sound and lighting alarm functions. Technical SpecificationsMechan

erection cost is not as high as that of wired LAN, the successfully deployed wireless LAN can be easily changed in the future. More importantly, the expansion of the wireless LAN network is very good. For example, it can be compatible with various network connection interface standards, supports and complies with all communication protocol standards. For common access users, it is almost a completely transparent link that can meet the access needs of various client systems. With the help of Wir

Wireless LAN technology is becoming more and more mature, but many people are not clear about the wireless LAN networking method. Here we will summarize some specific methods for you to learn. Wireless Networking 1 wireless networking Networking requirements: Establish a network without a line in the LAN to share resources among devices. Networking Mode: place a wireless access point in the LAN center and add a wireless network card to the Internet device. 2-point-to-point wireless networking ①

There are many networking methods for wireless networks. which method is suitable for our work environment? Here we will give a detailed description of the networking requirements. Many of us are not clear about the typical networking methods of Wireless LAN, But what operations should we do? The following describes several typical methods. I believe this article will be helpful to you. Wireless Networking 1 wireless networking Networking requirements: Establish a network without a line in the L

wireless route, it will also seriously affect the transmission of wireless signals. 6. Adjust the antenna Angle During use, the antenna angle is also worth our attention. Through the adjustment of the antenna angle, we can think of the enhancement of the coverage intensity of wireless networks in some areas, enhances the stability and transmission rate of the sp

sources to interfere, which naturally causes the WLAN transmission speed slows down. In addition, 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. Knowing the slow speed of transmission, we can begin to solve the problem with a targeted approach. First in the layout

Knowing the slow speed of transmission, we can begin to solve the problem with a targeted approach. First in the layout

the RF signal of the radio transmitters output is transmitted to the antenna via a feeder (cable) and radiated out by the antenna in the form of electromagnetic waves. When the electromagnetic wave arrives at the receiving location, it is received by the antenna (only a small fraction of the power is received) and sent to the radio receiver via the feeder. Ther

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

occur, reducing its transmission range. Therefore, do not hide a wireless router in the corner of the room, or bury it in the basement or in the shelve, instead, try to place the wireless router in the center of your wireless activity. For the duplex room, try to place the wireless router in the center of the room So how can we identify such a central location? In fact, the simplest way is to observe through your line of sight, that is, where you can see the most room scenarios, then this
