For solutions with weak Wireless LAN signal, the problem of Wireless LAN signal is very hot. As the name suggests, there are many ways to solve the problem of Wireless LAN signal, that is, the virtual network channel of the wireless router. This article also introduces several popular wireless routers on the market. Q: I am now using a wireless LAN, but I feel that the data transmission speed is very slow. Is there any solution? A: It is estimated that the signal status is poor. You can try to a

will not be perfect. After all, those obstacles will directly affect the normal transmission of data signals in the wireless LAN. 2. When the distance between the remote network and the local LAN is relatively long, we can appropriately reduce the size of the network transmission bandwidth to achieve the purpose of long-distance data transmission. If we really need to implement long-distance wireless transmission, we may try to set up a wireless LAN relay station in the middle so as to bypass t

overlapping frequencies, and can even theoretically overlap to an infinite number. However, to increase the sensitivity of demodulation, LTE currently supports half of the overlapping wavelength of OFDM. MIMO In fact, one of the important reasons why LTE abandoned CDMA in the Early Days was that CDMA had poor support for MIMO, while the sub-carrier data used by OFDM was converting serial data into parallel data, parallel data can be well adapted to MIMO reception. (For the reason why CDMA is no

Wireless Networks are no stranger. Laptops and smartphones can all access wireless networks. This is what we often do in our lives, however, many people may encounter various usage errors when using wireless networks. I. The main factors affecting the wireless network are transmit power, accept sensitivity, and antenna gain. Currently, the main trend of wireless networks is in signal coverage and transmission rate, generally, the method to enhance the

radiation coupling. Transmission must have a complete circuit connection between the interference source and the sensor. Interference signals are transmitted along the connection circuit to the sensor. This transmission circuit can include the power supply, public impedance, grounding flat, resistance, inductance, capacitance and mutual inductance of wires, conductive components of the equipment. Radiation transmission is carried out in the form of electromagnetic waves, and the interference en

the user's device. The ground monitoring system of GPS working satellite includes one master station, three injection stations, and five monitoring stations. GPS signal receiver the task of GPS signal receiver is to capture the signals of the satellite to be tested selected based on the cutoff angle of a certain satellite height and track the operation of these satellites, transform, zoom in, and process the received GPS signals to measure the transmission time of GPS signals from the satell

example, some users put a wireless router near the microwave, and found that when the microwave oven work, the wireless network will appear inexplicable network failure, and the microwave after the network back to normal. Small fat found a lot of colleagues in the use of walkie-talkie, and in the intercom "harassment", the wireless network will naturally be affected. Therefore, it is also necessary to keep the "purity" of the wireless network environment as much as possible. Xiao Fat reminds

radiation transmission mode. Therefore, from the disturbed sensors, the interference coupling can be divided into two kinds: conduction coupling and radiation coupling. The conduction transmission must have a complete circuit connection between the jamming source and the sensor, and the jamming signal is transmitted to the sensor through the connection circuit, and the interference phenomenon occurs. The transmission circuit may include a conductor, a conductive component of the equipment, a p

meters, outdoor farthest not exceeding 50 meters. In addition, the antenna with high gain can be considered to solve this problem. Because of its no directionality, omni-directional antenna is used in the central station of point-to-point communication. Directional antenna has the maximum radiation or receiving direction, so the energy concentration, the gain r

price is hard to accept. However, it should be emphasized that each product has its own market positioning, wireless packages are mainly facing the "impoverished" of the primary users. Those who already have a certain basis to buy wireless package although some inconvenience, but not necessarily spend money. Here is a kind of practice is worth learning: in the market to find a "like-minded" friends, two people need to buy a set of wireless package. Contact each other before you break up so tha

Wireless network systems can cause serious security problems if they do not take appropriate security measures, whether the wireless system is installed at home or in the office. In fact, some providers of Internet services for residential areas have banned users and other unauthorized people from sharing networking services in their service agreements. An insecure wireless network can cause services to be lost or exploited to launch attacks on other networks. To avoid some of the similar wirele

There are several possible causes for this failure: (1) wireless network card distance from the wireless AP or wireless router is too far, more than the coverage of wireless networks, wireless signal to reach the wireless network card has been very weak, so that wireless clients can not be normal connection. (2) The wireless AP or wireless router does not power up or does not work properly, causing the wireless client to not connect at all. (3) When the wireless client distance from the wir

First of all, let's take a look at some of the wireless product hardware indicators: transmission power, acceptance sensitivity and antenna gain. At

wireless bridge connects an antenna to form a bridging relay to ensure high-speed wireless link communication. The two back-to-back APS can be in different frequencies and work in the wireless bridge mode at the same time, so that their functions can be expanded and the signal can be maximized during the forwarding process. Increase the bandwidth and speed to the maximum, so as to meet the high requirements of users, to ensure their smooth degree.

The starting point of establishing a secure wireless network access node (access point) is to prevent information leakage from unauthorized external access. This principle is often difficult to understand. The security settings of wireless networks are much more complex than those of ordinary cable networks, because the access nodes of the cable networks are fixed and within the signal sending and receiving range of wireless networks, all nodes can be connected. Problems caused by the characteri

The previous article introduced the basic introduction of the built-in wireless network card. I think you have some knowledge about some common types of built-in wireless NICs. Next we will talk about the selection and upgrade of the built-in wireless network card. Hope to help you. ◆ How to select and upgrade a built-in wireless network card If conditions permit, you can choose a laptop with a built-in wireless network card, which is more convenient to use. Of course, laptops with built-in wire

confidence, and it will never be "fooled ". These four aspects are: Brand and design, quality and performance, simple and easy to use, and the key is price. 1) brand and Design Needless to say, a large brand determines everything about the product, and network products are no exception. A good brand includes the product quality, quality, and after-sales service. Please note: do not purchase products from small factories. The products of small manufacturers cannot guarantee quality or provide st

GPRS card. I will explain for you how to install and use the wireless network card when using the hardware device: wireless network card is a product from South Korea's different show YISO, notebook is COMPAQ's EVO N800C. When I first selected yixiu YISO, the wireless network interfaces on the market were not as rich as they are today, and there were not so many products of domestic brands, and the price was high. Yixiu adopts the built-in antenna an

To minimize the risks caused by security vulnerabilities, make sure that network technicians configure and test according to the following suggestions. Wireless Network Application configuration 1. Configure the antenna installation location This is the first step to achieve "non-leak" wireless access nodes. the wireless signal coverage is used to determine the location o
