. 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

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

, the entire system is typically a wireless system, such as the Code division used in multiple antenna systems, 3G mobile phone systems (wireless systems) multiple Access (CDMA) systems, even DSL systems (wired systems) that generate crosstalk (crosstalk) using multiple phone lines. This paper will first introduce the history background and operation of MIMO, and discuss the extent to which MIMO can extend WLAN transmission range. The development pr

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

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

What a different feeling to look down from such a high place he had never been to before! However, he was very tired due to the long time of climbing, and fell asleep. an unbelievable thing happened when he woke up ---- he found himself lying in a meadow and his house originally

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

the body (MINI-PCI or mini pci-Express) and a preset antenna. In this way, you only need to purchase the wireless network card of the corresponding interface and connect the antenna. If you have an expansion slot (MINI-PCI or mini pci-Express) that is not cabled, you can also install and use the antenna after purchasing it. There are two types of expansion slots

In most home environments, only one router is used for wireless network coverage, a single wireless router has limited coverage, and wireless signals in some areas may be weak or cannot be found. This article describes how to enhance the coverage effect of a single wireless router. If the housing space is not open enough, there are partitions, walls and other obstacles, will lead to wireless signal penetration attenuation is too large, the scope of the coverage is gre
