On optimizing the performance of wireless network

The speed of the wireless network is always unsatisfactory, so how can we improve our existing wireless environment? What can be done to optimize the performance of the wireless network? What should be used in the meantime? This article will answer these questions for you.

If your Skype or Second Life application starts to break down frequently, or if your itunes transfer stream becomes congested when someone starts a World of Warcraft game, you should consider how to improve the problem without having to buy a new device. In the past few years, most of the wireless routers sold have QoS features, but you may want to be able to update the router's firmware to solve the problem.

Take a Linksys router for example, and if you want to optimize wireless network performance, we can make some changes by configuring the program. First make sure your device supports WMM (Wi-Fi multimedia), so you can find the QoS menu in the Apps and games option. Then, configure Internet access Priority (Internet access priority) to your voice and multimedia applications. At this point you can choose from each specific application of the Pull-down menu, then you can select the priority level (high, medium, Normal, or low) and click the Add button. For example, you can set a lower priority for BitTorrent and other download services, while giving your VoIP service a higher priority.

When it comes to WMM, it is actually a subset of the IEEE 802.11E Standard, 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 works well for data traffic from applications such as Web browsers, file transfers, or e-mail, but this is not a good way for multimedia applications. VoIP, video streaming, and interactive gaming are highly sensitive to increased latency and reduced throughput, and WMM shortens the transmission time of packets with high traffic priority. The

WMM, based on enhanced decentralized channel access (EDCA), defines a prioritized set of media access categories that can shorten the transmission time of packets with high traffic priority. The Wi-Fi Alliance has also introduced the WMM node authentication feature, which allows you to customize the power mechanism based on specific applications, save power without sacrificing service quality, and extend the battery life of 15% to 40% of terminal equipment.

Currently, more and more products support the WMM feature in VoIP phones, televisions, gaming consoles and other consumer electronics that support Wi-Fi, as are the associated wireless router devices.

In addition, some devices can also help you toThe priority is set on a specific voice device to optimize the performance of the wireless network. For example, a VoIP phone connected directly to your wireless network. At the same time, not all routers can be configured with a priority on a specific application or device. However, you can at least start QoS or WMM features that will help you automatically optimize the streaming of multimedia, which is turned off by default in many routers.

Wi-Fi optimization wireless network performance essentials:

in your Wi-Fi router configuration program to launch the appropriate options to achieve the optimization of multimedia bytes;

Identify the application priority in your wireless network one at a A-list of Internet access priorities;

should give your voice and multimedia applications a higher priority than a download service such as BitTorrent.
