What Is IEEE 802.11e?

IEEE 802.11e is a standard developed to help ease the transition between the OSI model's physical and data link layers. It helps with prioritization, and it's been around since 1999. The reason it's so important to prioritize wireless LAN applications is because they can be sensitive to delay. For example, if you're trying to watch a video on your phone or tablet, you probably want it to stay calm whenever someone else gets on their phone in the same room. 802.11e is also essential for the voice-over-internet protocol (VoIP), which needs reliable bandwidth so that people can hear each other clearly during calls. 802.11e is the future of your internet. You want to ensure your connection stays active when surfing the web. You want to be able to stream videos, watch full-motion videos, and listen to high-quality audio without interruption. 802.11e offers all this and more, operating at radio frequencies ranging between 2.4 GHz and 2.4835 GHz or between 5.75 GHz and 5.850 GHz. These higher frequency ranges account for advantages such as more channels, fast data transfer speeds and fewer chances of interference. 802.11e is a standard that's all about prioritizing the important stuff. The more we use our wireless devices, the more critical it is that we can get things done quickly and efficiently. Video, data and voice transmissions are all equally important to us, and 802.11e ensures those transmissions happen simultaneously without interruption or delay. That's not all: 802.11e also enhances the MAC layer with coordinated time division multiple access constructs and adds error-correcting mechanisms for delay-sensitive applications. In other words, if you're using one of those fancy new phones with a built-in camera, you can be assured that your pictures will come out just as clear as if they were taken on an actual camera!
