, which defines the quality of service QoS for Wi-Fi ). Without QoS, all applications running on different devices have the same opportunity to transmit data frames. This method works well for data traffic from web browsers, file transfers, e-mails, and other applications, but it does not work for multimedia applications. VoIP, video streams, and interactive games are highly sensitive to the increase in lat
Wi-Fi Alliance announces the completion of Wi-Fi direct standard, so that Wi-Fi devices do not need to connect to traditional home, office or hotspot network, you can achieve mutual connection, the relevant equipment certification work has begun, through the certification of products will get Wi-Fi certified
5 things that will reduce the speed of the Wi-Fi network, will reduce the wi-fi5
By using the old protocol, overlapping channels, and low data rates, Wi-Fi networks may become slower. The following describes how to solve these and other performance problems.
Wi-Fi (Wireless LAN) is quite easy to change. Competition be

Today's Wi-Fi has become the basic level of Maslow's demand theory, and its importance to modern people is no less than physiological needs. The most critical device for connecting to Wi-Fi is a wireless router. It is especially important to place a home rou
The Wi-Fi Alliance named "Halow" for Low-Power Wi-Fi"
A few days ago, the Wi-Fi Alliance announced the certification program at the Consumer Electronics exhibition in Las Vegas, USA. When enterprises purchase a Wi-Fi Halow product, they can ensure that the product uses 802.11ah technology developed by the Institute

I. What are the statuses of the Wi-Fi network card?
WIFI has the following five statuses, which are actually plastic constants:
1. WIFI_STATE_DISABLED: WIFI is unavailable,The value is:1.
2. WIFI_STATE_DISABLING: the WIFI is being disabled. Because the WIFI is being disabled, this status indicates that the WIFI is be

Using Network Service Discovery, showed you how to discover services that are connected to a local network. however, using Wi-Fi Direct trad; Service Discovery allows you to discover the services of nearby devices directly, without being connected to a network. you can also advertise the services running on your device. these capabilities help you communicate between apps, even when no local network or hotspot is available.

Now there is a closer plan to integrate Wi-Fi with the mobile network ecosystem, but it is not completely holistic. At present, Wireless Broadband Alliance (WBA), Wi-Fi Alliance, 3GPP and other industrial institutions are promoting cooperation between Wi-Fi and mobile infrastructure in a nearly seamless

By jumping in a limited channel, the problem is even more problematic than it solves.In the most widely used 2.4GHz Wi-Fi band, there are only three non-interfering channels in total. Even in the 5GHz band, there are only 4 non-overlapping 40MHz wide channels after the removal of the dynamic frequency selection (DFS), a mechanism that allows unauthorized devices to share the spectrum with existing radar systems.

Figure: Available channels for 802.11 working in the 5GHz bandThe change channel operation performed by the AP requires that the connected client be detached and associated again. This will cause interruptions in speech and

Changing the channel also creates a domino effect, as the adjacent AP also needs to change the channel to avoid interference with the channel. When the device uses the same channel or radio frequency

Wi-Fi is an effective means to enhance the value of wired broadband users and provide differentiated services. It is also a powerful supplement to 3G data services in the future. 3G can use the features of WIFI high-speed data transmission to make up for the limited data transmission rate. Within the Wi-Fi network coverage, users can access the comp
draft-802.11n routers have increased the border rate of wireless routers to 54 Mbit/s, the actual throughput can reach about 90 Mbit/s, has formed a competitive situation with wired Ethernet. This year, the Wi-Fi Alliance began to authenticate draft-802.11n routers. If you want to purchase a new router in the market, simply purchase the products of these types. However, if your old router provides satisfactory performance, you do not need to upgrade
