1. Joining direct to trust Center
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.

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
Common Terms for network advertisement billing methods:Terms highlighted: CPA CPL, CPC, cpm, and CPS"1. CPA (cost-per-Action): the cost of each action, that is, the pricing model based on the actions each visitor takes on online advertising. There are special definitions of user actions, including forming a transaction, obtaining a registered user, or clicking on an online advertisement.Cpl (cost for per lead): pay commission based on successful regi
Any online advertising system, are faced with the problem of ROI, for Invest, we do not consider, because there are many ways for traffic can be bought back, also can not be optimized (of course, when RTB is optimized). Return is the main optimization direction,return= Ctr * Value created per click. For example: click-through rate is 10%, each Click brings the benefit is 5 yuan, then the profit of each hit is 10% * 5 = 0.5 Yuan.There are two very important concepts in the calculation of advertis
controllers and APs. Later, this article will explain the variables related to the second/third-layer movement in the centralized architecture, and finally point out some common incorrect ideas and actual situations about these architectures. This article uses the term wireless terminal (WTP) to refer to the AP, and the term Access Controller (AC) to refer to the WLAN control function (whether deployed on a WLAN switch or an independent Controller ).
With a cup of fragrant coffee, you can freely talk to netizens in any corner of your home. This is the charm of wireless! With the rapid development of Wireless networks, Wireless LAN Wireless Local-Area Network (WLAN) has become the first choice for many SOHO networks. Although wireless networks are becoming increasingly popular today, wireless networks are new things after all, so many netizens are confused about wireless network products.Today, we distinguish between a wireless router and a W
Wireless LAN is a commonly used network in enterprises. Therefore, for an enterprise's network configuration, how to use wireless LAN switches, wireless routes, and Wireless AP devices is an ideal and reasonable solution, facilitating network management is a question worth thinking about. Here we will mainly introduce the wireless LAN switch, which serves as a "traffic police" in our daily life, so that our network can be kept smooth and our network can be properly guided.
Wireless LAN switches
Today, we distinguish between a wireless router and a Wireless AP in terms of functions, applications, networking, and costs.
The current Wireless AP can be divided into two types: Hybrid AP and extended AP.
The routing function is relatively simple for balanced AP. It can only be equivalent to a wireless hub. For such Wireless AP, no products can be connected !! The extended AP is also a wireless router on the market. Because of its comprehensive functions, most extended
Do you want to achieve a signal without interference and a stable wireless network connection? WLAN wireless LAN switches can be configured to fully control wireless access points. How can this problem be achieved? The following articles will give you a detailed introduction.
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
When we build a wireless network, WLAN switches are like a mainstay and cannot be ignored. Therefore, setting a vswitch quickly means that a WLAN Network is successfully created.
A wlan switch can connect to a WLAN Access Point (AP) through a wired connection (with a switch port ). They can also connect to the enterprise network through their other WLAN switch ports. These switches are the "gateways" connecting to the enterprise's wired network-all data frames from the WLAN client must be sent t
WLAN switches are quite common. So I studied the functions of WLAN switches and how to quickly implement the networking scheme. I would like to share with you here, hoping to help you. A wlan switch can connect to a WLAN Access Point (AP) through a wired connection (with a switch port ). They can also connect to the enterprise network through their other WLAN switch ports.

For this kind of problem, router generally limits the number of Pin_lock_down, if it is 5, then the verification 5 times will lock, not let pin.The client pin is a randomly generated pin for the wireless client, and when connected to the router, enter it into the router to authenticate the connection, which is safer than the router pin.When the PBC button is presse

What is RTB?RTB is short for Real Time bidding. Before explaining what RTB is, let's take a look at some of the traditional purchase modes in the current display ad market:
CPM: cost per 1000 impressions-pay for each 1000 impressionsCPC: cost per click-pay by each clickMonthly flat: monthly advertising spaceDaily flat: advertising space package day
Compared with the traditional purchase method above, RTB is bidding based on the impression of each adve
