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

Q: No line from the living room, but in the bedroom signal is relatively weak, what is the solution? A: No line by the signal strength and the route itself, the receiver's wireless network card, the use of distance, the middle interval of the number of load-bearing walls, and so on, and even with the neighbor's home without the number of lines are also related. Method One: Antenna gain Normally, no line from through a load-bearing wall

wireless network card between the best to see, as far as possible to avoid the wall between them, especially the load-bearing wall (reinforced concrete wall). We know that in order to reduce the radiation on the human body, the 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 house

, configuration, frequency point, latitude and longitude, antenna height, antenna gain, antenna half power angle (vertical and horizontal), azimuth, elevation, base station type, etc. Prepare a map indicating the station number, frequency point, BSIC, and azimuth (antenna direction), and record the current system versi

. Therefore, I prefer to purchase a Mbit/s router or a Mbit/s router. After all, the network device update iteration is slow and a vro takes a long time to use, it is necessary to leave room for network bandwidth upgrade in the future. Of course, for users with simple network needs, a low-price M router is also a good choice, and there is no best product in the world, if you make the best of your resources, you are the best choice. blindly pursuing performance leads to performance redundancy, wh

Check that there is a mobile phone signal amplifier in the market. I don't think it's too expensive. The poor have to find a solution, so Baidu and Google have joined hands to save money and solve the problem! Finally, I found a way to enhance the mobile phone signal with chopsticks and tin paper. by sorting out similar data, I found this method, and then I bought two pieces of tin paper and chopsticks, I tried it several times, but it still seems to be effective! Now, let's summarize this metho

systems without knowing any codes at all simply by being closer to our target.This tutorial would show you a technique to use this effect to hack civilian FM radio bands and play your own social engine ering payload. Maybe you simply don't like the music a radio station in a particular business or vehicle are playing and you ' d like to PLA Y your own. Maybe you ' d like to play a message to get your the target to does something you want them to. Whatever The goal, all your really need to rebro

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

Figure 6 Add a lovely bun to the baby girl 7, to the little girl to add lovely eyes and mouth, only need a few straight lines and bending deformation on them can be, and powder toot small gills, in addition to two ellipses, but also need to the padding edge feather, so as to achieve a natural halo effect. As shown in Figure 7. Figure 7 Add a lovely facial

fragile paper. 14. Fixed speaker Structure The volume of a mobile phone is a strong selling point, which puts forward higher requirements for the speaker. in addition to requiring the solution company to tone the speaker itself to the best state, the speaker's sound cavity structure should also pay attention to the following points: A. the front sound of the speaker must be closed. if the horn works directly with the shell, the ring foam must be closed between the horn and the shell, and the

performance a Wi-Fi system can achieve. The higher the SINR value, the higher the data transfer rate, and the greater the spectral capacity.　　 Figure: SINR is an important indicator for determining the performance of Wi-Fi systemsIn order to obtain a higher SINR indicator, Wi-Fi systems must be achieved by increasing signal gain or reducing interference. The problem is that traditional Wi-Fi systems can only increase the signal strength in a direction by increasing power or by erecting hi

difference between the level of signal and the level of interference. Because it reflects the negative impact of RF interference on user throughput, SINR is a better indicator of what performance a Wi-Fi system can achieve. The higher the SINR value, the higher the data transfer rate, and the greater the spectral capacity.　　 Figure: SINR is an important indicator for determining the performance of Wi-Fi systemsIn order to obtain a higher SINR indicator, Wi-Fi systems must be achieved by i

MIMO technology can be used as a bridge to connect old and new wireless technologies, so that the two can develop and integrate harmoniously. So it is already an important technology in the next generation of wireless broadband mobile communication systems. The following will give you an in-depth analysis of its development. MIMO technology has become one of the key technologies in the wireless communication field. However, it is a huge challenge in the industry to reduce the algorithm complexit
