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

will also increase. Currently the international regulation of the maximum launch power of 20DBM (or 100MW), but now the market most of the products are not up to this value, we are in the choice of course the closer the better. Wireless Router selection standard 3, antenna gain Wireless products are mostly antennas, this antenna can be good or bad for wireless products have a direct impact on the selecti

ordinary users 54M products can fully meet the needs of the Internet. 2. Transmitting power: We know that the unit of measure of power is watt. In the same way, wireless devices also use transmitting power to measure the performance of the transmitter. The unit of measurement for transmitting power is dbm or MW. Like the relationship between the brightness and wattage of a light bulb, the transmission distance of the wireless device is also connected with the transmit power. With the increase

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

We have learned about Wimax wireless technology before Wi-Fi wireless technology. This article will introduce the Wi-Fi wireless technology. Wi-Fi wireless technology is a LAN, which has some limitations over Wimax. For more information, see the following section. Overview of Wi-Fi wireless technology WLAN standards mainly include 802.11b, 802.11a, and 802.11g. Currently, WiFiWirelessFidelity, a wireless f

The coexistence of wired and wireless networks has a wonderful effect on the combination of wired and wireless networks. It can be cleverly designed for different situations to fulfill the WiMax wireless standard prospects. Combine the advantages of the two to make the network ubiquitous. With the maturity of the broadband technology and the decrease of the market application threshold, the ADSL Broadband business has gradually gained the recognition

There are times when we may encounter a problem with installing the two NS version at the same time, such as I study wimax/802.16, because the protocol is too complex to use the WiMAX patch of Chang Gung University and NIST. Chang Gung University's WiMAX patch was developed under ns2 , NIST's WiMAX patch can be used o

-distance workAlthough Wireless WiFi is far from working, the actual working distance of 802.11b can reach more than 100 meters in the case of complete network construction, in addition, it solves the problem of data correction and error codes during high-speed mobile. The switchover and security authentication between Wi-Fi devices and devices, devices and base stations are well solved. Development and Future of WiFi In the past two years, the number of wireless APS has increased rapidly, and t

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

multi-dimensional transmission scheme: one single RF channel is used to send and receive two or more signal streams. As a result, the wireless communication system can transmit data twice or more in a channel. In the system, use more than one high-integration RF upconverter) and antenna to transmit these multiple signals, and there is also more than one high-integration RF downconverter) and the antenna to
