channel in the default configuration of the router, which is prone to channel interference. If nearby neighbors use the same channel as ours, our wireless signals will be affected. We can also use the Network Stumbler software for scanning to see which wireless signals exist nearby and which channel is used. Then modify our own wireless channels to avoid duplication with other channels. In addition, you should note that the signal of a channel will interfere with two adjacent channels at the sa
one, human factors The distance between the wireless router and the network card is too long, in this case can only be solved by a different configuration of the appropriate antenna. The wireless router and the network card have the obstacle influence, sometimes also can cause the disconnection breakdown, for instance the indoor complex environment, the wall, the furniture influence. So try not to go through walls over three floors as much as possib

You can support business with different quality requirements, such as voice and packet data, and ensure high quality and perfect coverage. (2) High spectrum efficiency. WCDMA can efficiently use the radio spectrum. Since it uses single cell multiplexing, frequency planning is not required. The network capacity can be greatly improved by using the layered cell structure, adaptive
Today's home routers usually bring a few antennas, long, the appearance is not good-looking, but most users like, think has the antenna router launch out of the signal will be very good, even in the home more remote corner, mobile phone show WiFi signal is also full, that is to wear a wall effect is very good, is this? The first thing we need to sort out is the weak WiFi signal for routers and mobile phones. Because the mobile phone's main function

(1) Verification A Verify all information related to wireless in the database: including site coordinates, structure type, antenna position, antenna
The development and prosperity of wireless networks are inseparable from the construction of networks. However, problems such as poor planning or adaptability to the current environment may also occur during the construction process. Then we need to optimize the network. Next we will introduce the optimization of CDMA wireless networks. The CDMA system needs to be gradually expanded and optimized during the operation process, and most of the problems in the mobile communication network are unpre
Source: CCID In most cases, frequent wireless connection disconnection is caused by improper use. It is usually manifested in faults such as weak wireless signal, difficult connection, slow communication speed, and disconnection. The reason is generally caused by the following factors. 1. Human Factors The distance between the wireless router and the network card is too long. In this case, you can only configure an appropriate antenna. There are obsta
port of the wireless routing product. For network products in long-term working conditions, the advantages and disadvantages of the Heat Dissipation Capacity will directly affect the product stability and service life, so by carefully observing the shell material, heat sink port and volume, we will probably get some information about the product's heat dissipation performance. Of course, this is also one of the best methods to detect wireless routing products before purchase. 3. view the
Day-feed coverage, as the name implies is the use of AP, feeder, plus ceiling antenna to build wireless network. thereby reducing the use of APS to reduce the interference of the same frequency.Working principle:Day-feed coverage using APS are high-power industrial wireless APs, power is the general home wireless router 7-8 times, is the general ceiling-type AP 5-6 times, high-power is to ensure the basic coverage effect. The greater the power, the be
The lab bought two DAP1360 devices for wireless network coverage and found that the ap signal was okay, but after passing through a load-bearing wall and two thin walls, about 30 meters away, there are only two weak signals in the notebook, and the effect is not satisfactory after a relay. The two APS load 20 laptops, 7x24 for a week, there is no problem.According to the ap user documentation, we learned 7 working modes of this ap:1. ap mode: connect to an existing wired network through the lanp

Unfortunately, the effect let me down, because after the use of the code, you will find that the trapped time is from after thawing to calculate. And at this time, sister will use the knife chop. Note here, is a knife and even chop, but not just to a pitch. In peacetime, she will only come to the end once. This time she was so cruel (as for the sake of my handsome, don't cut your face)In order to dea

Tip : The first use of the router, set up hot signal amplification (WISP) mode will appear in the process of Easy-to-use interface, you need to skip these interfaces, login to the Advanced settings interface set hotspot signal Amplification (WISP
, which allows you to buy a wireless network card separately ". The built-in MiniPCI wireless Nic does not integrate a signal antenna. Therefore, to install the MiniPCI Nic, in addition to requiring the laptop to reserve a MiniPCI slot, you must also have a preset antenna or a preset antenna. Not all brands of MiniPCI interface wireless NICs can be used in any mo
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 better sensitivity. It can adjust the direction of the antenna to receive better signals. The built-in antenna
1. DBM DBM is the absolute value of power. The formula is: 10lgp (power value/1 MW ). [Example 1] If the transmit power P is 1 MW, it is converted to dBm and then 0dbm. [Example 2] for 40 W power, the converted value in dBm unit should be: 10lg (40 W/1 MW) = 10lg (40000) = 10lg4 + 10lg10 + 10lg1000 = 46dbm. 2. DBI and DBD DBI and DBD are the obtained Gain values (power gain). Both are relative values, but the reference standards are different. The reference of DBI is a full-direction
Several employees in unit A usually use laptops. Due to work reasons, they need to set up wireless networks for resource sharing. Also, several employees in Room B need wireless networking; by nature, building A slightly larger Wireless LAN can meet the wireless Internet access needs of all employees in Room A and room B. Considering the security concerns, the company intends to build A wireless LAN for several employees in Room A to prohibit employees in other offices from accessing the privacy
receiving devices located behind the obstacle will receive very weak signals or fail to receive signals. What about penetration? This is what many netizens are most concerned about. We all hope that wireless signals can penetrate the walls of the house at least. To improve the ability of wireless signal to penetrate the wall, an effective way is to improve the antenna gain. We 'd better choose a product with a high
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.
