long. At the same time, each office has set up its own lan. Now we need to connect the two offices. However, due to the obstacles in the middle of the two offices, cabling is not convenient, in this case, two wireless APS can be used to connect the two wired LAN networks to achieve wireless interconnection and resource sharing, as well as the expansion of the wired network. In this way, network cabling is saved, which is easy to operate and reduces c
AP coverage area should be determined based on the received signal strength. A) set a signal strength threshold. All areas whose signal strength is not lower than this threshold value are determined as AP coverage areas. B) conduct on-site measurement to form an AP coverage area map. C) adjust according to positioning principles until the requirements are met. Users in different regions have different user density. Generally, areas with high user density are more complex. Therefore, you should

derivation, the problem of the objective function finally becomes: the minimum value of the following objective function is obtained.In order to solve these multiplication, each time the two A1 and A2 are extracted from any of them, and then the other multiplier is fixed, so that the objective function is just a function of A1 and A2. In this way, the problem of solving the original problem is solved by continuously solving the sub-problems by random
right, here I go. BIOS settings Guide, before you overclock to explain to everyone what is called overclocking and overclocking principle, so that you can better enter the next step of the BIOS setup overclocking!CPU overclocking, its main purpose is to improve the CPU operating frequency, that is, the CPU clock. The CPU frequency is the product of FSB (FSB) and octave (Multiplier Factor). For example, a CPU FSB is 200MHz, the
The topic here is the constrained optimization method, the Lagrange multiplier method (Lagrange Multiplier) and the KKT condition are very important for solving the constrained optimization problem, and the Lagrange multiplier method can be used to find the optimal value for the optimization problem of equality constraint. If there is an inequality constraint, th

Once the transport key is received by the joining device, it'll proceed to check the ' source ' of this Transport key command. In this case the 64-bit IEEE address is different from 0 's and FF ' s, since the TC exists in this network. The following steps describe the unsecure joining process to a centralized network.

Breaking through the bottleneck in upgrading Wireless LAN
When planning a wireless LAN, it is important to consider the installation and connection of the new 802.11n AP to the enterprise network.
Some new APs may be connected to the existing limited-capacity WLAN
Roaming in a wireless LAN ----Configuration and application of wireless roamingAt present, wireless networks have quietly become the new favorite of modern office work, but the coverage of a single AP is limited. Therefore, some companies with large coverage often place two or more aps, wireless networks can be used within the company, but this is a problem. When mobile users switch between different APs, t
In many cases, wireless technology is not a single use. The combination of wireless technology and other network devices is the current trend. How can we control interference with signals on networks?
There is no interference in the signal and seamless network switching, so there is a wireless network connection method that can achieve this effect. It is also a pure wireless connection solution. The difference is that it slightly controls the traditional Wireless AP (Access Point)-deploy a switc
Innovation is based on previous people's experience and knowledge to create new technologies. Combining existing things often creates unexpected results. This article introduces you to a new idea. You can use WLAN switches to master wireless APs and broaden the world of wireless networks.
Wireless Network Access bottlenecks
We all know that the emergence of wireless networks is to achieve network access through a certain range of signal coverage witho
Algorithm DesignIf you use the "obtain the square of a number and then extract the last corresponding digits" method, it is obviously not desirable, because the computer cannot represent an excessively large integer.Analyze the calculation process of the integer square (multiplication) in the manual mode.

I.SMOAlgorithmPrinciple
The SMO algorithm is similar to some SVM improvement algorithms in the past. It breaks down the whole quadratic planning problem into many small problems that are easy to handle. What's different is that, only the SMO Algorithm breaks down the problem to the smallest possible scale: Each optimization only processes the optimization problem of two samples and uses the analytical method for processing. We will see that this distinctive method has brought a series of incom
