Wireless router transmission and its influencing factors

Many friends have found that our actual wireless router transmission rate is not as fast as the product introduction, what is the reason for this? Is it the false logo that the merchant makes? In fact, the real reason is to see the article to understand the specific. The

Wireless LAN, also known as the WLAN (Wireless LAN), has become a networking method for more and more users. Wireless network installation is very convenient, do not need to rewiring. So it will not destroy the original home decoration, compared to the cable network, wireless network is much more flexible.

In the course of use, we found that although the WLAN does not have the trouble of wiring, and easy to use, but sometimes we will find that the signal is not very stable, data transmission speed is slow, it is basically difficult to achieve the relevant nominal wireless router transmission speed. For example, one label called 54Mbps (actually wireless router transmission rate of 20Mbps or so) WLAN network, but its display transmission speed only 11Mbps (actual transmission rate of around 4Mbps), 5.5Mbps (actual transmission rate in the 2Mbps or so) or lower, What should we do to deal with this situation?

First, we'll start with a simple understanding of the reasons for the slow speed of wireless network data transmission, radio waves in the air can easily be disturbed by a variety of obstacles, interference sources, which will naturally cause the WLAN transmission speed slows down. In addition, wireless network transmission distance is limited, although the general nominal wireless router 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. The

knows why the transmission slows down, and we can start to solve the problem with a targeted approach. First in the layout of the time we have to grasp, wireless router and equipped with 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 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 use two antennas, in general, more than one antenna product is better than a single antenna products in the transmission performance is more secure, if possible we try to choose two antennas or more antenna wireless router. In addition, the antenna gain size on the impact of data transmission is also very important, ordinary routers generally only standard antenna gain for the 2dBi omni antenna, but many high-performance wireless router equipped with is indeed 3dBi or 5dBi omni antenna. No doubt, in the same environment, the performance of the wireless router with the 5dBi omnidirectional antenna must beSuperior to the 2-3DBI omni-antenna products. So we can improve the wireless signal condition by switching to a high gain antenna. The matching between the wireless router and the network card is also an important factor to improve the speed of wireless data transmission, we know that the wireless transmission standard in the market has 802.11G, g+, N, B and many other standards, for example, we use the router is 108Mbps 802.11G + standard , but the wireless card uses the 11Mbps (802.11B) standard, so in its actual speed is certainly not up to 108Mbps, then we need to upgrade the network card to achieve the best compatibility effect. In the purchase of related products, we must choose to adopt the same standard wireless router and network card, so as to minimize the occurrence of compatibility problems.

Before we introduced the main hardware aspects of the transmission speed of wireless routers, in terms of software, reasonable settings also facilitate the provision of wire-free data transmission speed. We know that most wireless routers now support WEP or WPA encryption, although the use of encryption is effective to enhance the privacy of the home network, but it will more or less affect the speed of data transmission, for the general Home wireless network, WEP or WPA encryption does not work, So we can turn off or disable this feature. In addition, sometimes we can improve the performance of wireless transmission by upgrading the drive of the wireless router by connecting to the Internet.
