environment, the distance is short. Generally, the home wireless LAN equipment claim that the transmission distance is more than 100 meters, so the signal transmission distance is not a problem. However, the home environment brings about a new problem, that is, the home space is crowded and the space is not open enough. The walls in the room are the main obstacles. The wireless LAN uses wireless microwave frequencies. The biggest characteristic of microwave is that it is almost linearly transmi

transmit signals from the antenna to various directions. Therefore, it is necessary to consider the signal strength based on the transmission radius. If our router is close to the wall of the neighbor apartment, they will get part of our signal. As a result, we can try to place the router in the center of the home without considering the limitations of the desktop computer and the home modem. In this way, the signal strength sent by the router can sp

Wireless Transmission path analysis is an important step in wireless transmission network design, through the analysis of the transmission path to facilitate the network designers to choose the appropriate type of antenna (direction, polarization, gain and other indicators) according to the margin size of the wireless link, install the antenna height, select the appropriate feed cable and length. The follow

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

If you want to use humanresourse later, you can only use the name. // You can change the name by use the name propertty. The XSD name does affect he dataset class name. So you must change the dataset class name. 2. How to reference.

The total magnification of the electronic system is usually thousands of, tens of thousands of or even hundreds of thousands of, a radio from the antenna received from the signal to the speaker sound output, a whole to zoom in about 20,000 times times. In decibels, the logarithm is taken first, and the value is much smaller.(2) convenient operation. When the amplifier is cas

The combination of Wireless AP and wireless route is essential for network construction. For an enterprise, it is possible that a wireless LAN cannot be fully covered. It is especially important to combine Wireless AP and wireless router devices. This article provides a detailed introduction to this problem. Due to work requirements, there is now A need for both Departments A and B to connect wireless networks at the same time, but the employees of the two departments cannot access work informat

. The signal scattering from the center to the surrounding area is used. Therefore, an omnidirectional antenna is used in the selection of the antenna to facilitate signal transmission in all directions so that all directions can receive the signal. The antenna that receives wireless signals at the edge must adopt a targeted
