A good antenna is also an effective way to ensure the wireless transmission distance and Stability of routers. Some high-end wireless routers use dual antennas, generally, multi-antenna products

points or wireless routers as wireless base stations, basically not involving bridges. How wide is the coverage of common Wireless AP? According to the protocol standard, the coverage of IEEE 802.11b and IEEE 802.11g is: 100 indoors and 300 outdoors. This value is only a theoretical value. In practical application, in addition to signal connection, it also has the value of speed. Therefore, the actual use range of Wi-Fi wireless products is: 30 meters indoors and 100 meters outdoors (no obstacl

sometimes called space diversity because it uses multi-space channels to transmit and receive data. MIMO can be deployed only when the site mobile devices) or access point AP (AP) Support MIMO. MIMO can increase the wireless range and improve the performance. The 802.11n site connected to the old 802.11g access point can connect to farther distances at a higher speed. For example, if you use an old site, the connection speed from 25 feet to the access point is 1 Mbps, and the site speed is 2 Mb

, this naturally slows down the WLAN transmission speed. In addition, the wireless network transmission distance is limited, although the average wireless router nominal transmission distance can reach 100 ~ 300 meters, but in actual use, if there is a barrier, this distance will be sharply shortened and will cause data transmission to slow down. Knowing the cause of slow transmission speed, we can solve this problem in a targeted manner. First of all, we need to grasp the layout. It is best to

Many of you are not quite familiar with the linksys Wireless Route Test content. So here we have compiled a blog article to share with you, hoping to help you. The following is the specific content: Yu Xin Computer Co., Ltd., a merchant that has been discussed on the internet, purchased the protagonist WRT54GC for today's test at a price of 369. Take it home with excitement and tension, skillfully connect the cables, and put the CD into the optical drive. According to the wizard prompts, all the

, or when there is an obstacle, the distance should not be too long. If you really need it, you can set up a relay station in the middle to bypass the obstacle. During WLAN close-range transmission, in order to obtain the maximum bandwidth, you can connect the wireless bridge to a router that supports redundant channels, so that three wireless bridges can be integrated together, in addition, the antenna height is basically unaffected. Most WLAN device

First said equipment: linksys54gc-cn original 2DB antenna), dell410 comes with Intel pro/wireless 2200BG wireless network card Test environment of linksys for wireless routing: the small duplex building on the second floor of my house, which is about 120 square meters ). The route is placed on the computer chassis of the Study on the second floor of my house, and all the room doors are closed. The test lo

Obviously, it is estimated that the 18db in the box is not that high. however, all sorts of disgusting feelings force the brain. so I changed the radar-target

December 31, 2013, Shenzhen-on World Telecommunication Day (December 31, May 17, the "2013 Shenzhen terminal Radio Frequency Technology Seminar" sponsored by microwave radio frequency network, an industry portal website focusing on microwave, RF, and wireless technology, was successfully held at the default Hotel in Bolin, Shenzhen. This seminar will focus on the hardware design and testing technical difficulties and hot spots of next-generation LTE (4G) smartphones and 802.11ac (5g WiFi) wirele

can support a wide range of wireless network adapters, we recommend using a prism 2 Chip-based network adapter, this chip can be supported by all the tools we need to use during the cracking process. Wireless NICs generally have two types of antennas: External antennas and built-in antennas. If the purchased wireless NICs do not have built-in antennas, you must purchase another one. However, the advantage of an external antenna is higher gain and bet

CDMA networks, because the system uses Code division multiple access technology, all users use the same frequency band, mutual use of unrelated PN code as a spread code to differentiate, because of this feature, the existence of the same frequency interference is inevitable; at the same time, the amount of interference depends on the number of telephone users, the system capacity also changes (that is, soft capacity). From the subjective aspect, the main reasons for the same frequency interfer

The extensive use of wireless networks also brings about the security of wireless networks. Because wireless networks are different from wired network physical node access controllability, the security of wireless networks deserves our attention. For the current wireless network, we can improve the security of the wireless network through the following settings. 1. Disable unauthorized access The key to ensuring the security of wireless access points is to prohibit unauthorized users from access

own hardware. The wireless transmission rate is mostly 54 M, and the maximum is no more than 150 M. it is meaningless to have a high Router speed. Look at the brand. Be sure to select a big-brand product, because the chip that really determines the performance of the wireless router is its. The chips used by major brands are of high quality and stable performance. Some brands use low-end chips to reduce costs. Although some parameters are high, the performance is unstable. Look at the

One of the most prominent advantages of the Siemens SX1 mobile phone is that it supports stereo MP3 and built-in FM. Although the original stereo PTT headset is of good quality, it can also be used as an antenna with built-in FM, however, one of the traditional methods of using a Siemens mobile phone is to use a headset adapter to enable the use of standard 5mm stereo headphones, such as senhaiser mx300/400/500. Therefore, the modification of the SX1

, it can be widely used for interconnection between different buildings. In addition, according to different protocols, wireless bridges can be divided into 802.11b or 802.11 in the GHz band and 802.11a wireless bridges in the GHz band. In the absence of high obstacle peaks or buildings), a pair of fast networking and temporary networking for field operations. The distance depends on the environment and the antenna, and now 7km point-to-point microwa
