The data link layer of WLAN is used as the key layer for data transmission. To understand WLAN, you also need to know it in detail. Through the following explanations: In the protocol of IEEE 802.11, its MAC sublayer contains the media access mechanisms of DCF and PCF:  Meaning of DCF: Distribute...

PHY, the physical layer of IEEE 802.11, has the following history of technology development and technical standards:   IEEE 802 (1997) Modulation technology: infrared transmission of FHSS and DSSS Operating frequency band: operating in the 2.4GHz frequency band (2.42.4835GHz, 83.5MHZ in tota...

There are many nouns involved in WLAN. If you need to deeply understand the knowledge points of WLAN, you need to make a full professional explanation of each knowledge point so that you can understand this content more easily in the future.  Station (STA, for short).  1). The station (point), al...

WLAN can be defined in both a broad sense and a narrow sense: From a micro perspective, we define and analyze WLAN in both broad and narrow senses. In a broad sense, a WLAN is a network made by replacing some or all of the wired LAN’s transmission media with radio waves, such as infrared, l...

To understand data communication in the network is complex. In this article I’ll easy demonstrate how two computer get connect each other, transfer and receive data information also with the Tcp/IP five layer protocol.   What is Data communication? The term “data communication” i...

Managed switches are superior to unmanaged ones in terms of functionality, but they necessitate the expertise of an administrator or engineer to fully realize their potential. More precise management of networks and their data frames is made possible by using a managed switch. On the other hand, ...
