4ipnet Wireless Access Point Optimization Part 1

圖片
Hello, there! Starting from this week, we will introduce you how 4ipnet's access points enhance the overall performance of managed Wi-Fi. We will focus on the performance and security features of 4ipnet access points, and in the process clearly illustrate the differences between 4ipnet APs and regular consumer-grade APs.

Airtime Fairness

As networks migrate between wireless standards – previously from 11g to 11n, and now from 11n to 11ac – network operators are increasingly struggling with the tradeoffs between legacy client support and wireless performance. For example, when both 11g and 11n clients are connected to the same AP, an 11g client will take much longer (use more airtime) to complete the transfer of the same amount of data as an 11n client. To understand why this matters, we must first briefly explain how data is transmitted over Wi-Fi.

The fundamental concept behind wireless transmission is that two devices cannot transmit at exactly the same time in the same freque…
