VLAN Isolation Function of Ethernet Switch Before understanding, switch VLAN isolation function, we first to understand the ethernet switch: Ethernet switch is based on Ethernet transmission data switch, Ethernet switch each port can be connected to the host, generally work in full duplex mode, c...

 Optical fiber transceiver is a flexible and effective photoelectric conversion device that plays an important role in multi-protocol photoelectric hybrid LAN. Now, in order to better detect and eliminate link faults, some optical fiber transceivers have link failover (LFP) and remote fault (FEF)...

Let’s gain an in-depth understanding of IEEE802.11a in the WIFI protocol, which is the first protocol for the 5G frequency band.   1) Protocol Interpretation: IEEE 802.11a is a revised standard of the original 802.11 standard and was approved in 1999. The core protocol of the 802.11a standa...

Both IEEE802.11b and IEEE802.11g operate in the 2.4GHz frequency band. Let’s take a look at these two protocols in succession to help you gain a deeper understanding of the standards of different protocols.   IEEE 802.11b is a standard in wireless local area networks. Its carrier frequency ...

In wireless networks, there are many concepts and protocols involved. To better help everyone have a clear concept, we will explain it from the perspective of classification.   1. According to the difference in network coverage: Wireless networks can be classified as   Wireless Wide Area Network ...

A large amount of data was conducted on the IEEE802.11 protocol in WiFi, and its historical development is summarized as follows. The following summary is not a comprehensive and detailed record, but rather describes the mainstream protocols currently used in the market. IEEE 802.11, formulated i...
