in the middle of the sea? That's the bridge! Amazing! The total length of the Highway Bridge in Shenzhen Bay is 5545, and the length of the side bridge in Shenzhen is about 2040. The bridge is constructed according to the standard of the two-way six-lane expressway. The bridge deck is 38.6 in width and has a design life of 120, it is a cable-stayed bridge with single-tower single-cable surface Steel Box Girder. It is currently the widest and highest standard highway bridge in China. the bridge
different wireless access devices. Make sure each one of them is able to surf the internet efficiently and wirelessly. To adjust the antenna position to promote network performance Normally, wireless internet nodes or wireless router devices will be attached to the Internet antenna, and different models of equipment with the antenna is different, then the in
distribution of the AP. In certain cases, each of these three methods works well, but none of the three methods can fundamentally address the problem of radio interference. Today, the majority of the AP is the omni-polar antenna used in the market. These antennas transmit and receive at a comparable rate in all directions. Since these antennas transmit and receive at the same speed in any case, the only option for these devices is to confront the dis
IEEE802.11 and ieee802.11b standards, can easily increase the wireless LAN load capacity and reduce the total cost.The wireless network of 80,000 People stadium project is divided into two parts: wireless network backbone bridge part and wireless network indoor and outdoor coverage part. The backbone bridge part uses the wireless network Bridge and the directional antenna completes the wired network the extension, the covering part includes Shanghai
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. ElectromagneticWhen the 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.Therefor
). Troubleshooting: When mixing IEEE 802.11b and IEEE 802.11g wireless devices, be sure to set the wireless AP into a mixed (MIXED) mode, which can be compatible with both IEEE 802.11b and 802.11g two modes.

suspected that pilot contamination may exist, the first possibility is that there is not enough protection in pilot planning, and the other may be that the time tolerance of pilot channel of some base stations has a large deviation. For the latter, a transmitter tester can be used to test the potential base station. (Computer science) The user complained to the warning and network management reports that there is a problem with the call, and has ruled out base station and base station day feed
of wireless networks is much more difficult than ensuring the security of wired networks. Because the wired network only has a limited number of fixed access points, and the wireless network can be connected from any point in the range permitted by the antenna. Design antenna placement The first step to keep the Wireless Access Point Closed is to place the antenna

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
