The solitary contrast among WLAN and LAN is the transmission medium. While in the LAN we utilize wound pair links, or fiber optic links, in the WLAN we utilize the air as a transmission medium, that is, we use Wi-Fi innovation regularly.
With respect to the various guidelines that we can use in our switches, we presently utilize the Wi-Fi 4, Wi-Fi 5 principles, and if your switch is of the most recent age, it is conceivable that it utilizes the new Wi-Fi 6 norm. Contingent upon the hardware we have, it can have WLAN in a solitary recurrence band (ordinarily 2.4GHz), we can have synchronous twofold band (2.4GHz and 5Ghz) and we can even have gear with concurrent triple band (2.4GHz, 5GHz with channels « low "and 5GHz with" high "channels).
As you have seen, presently in switches we have three very much separated interfaces, the WAN (Internet) interface, the LAN interface and the WLAN that have a place with the home neighborhood. Obviously, on the off chance that we have an expert switch, for example, the NETGEAR BR500 or the ASUS BRT-AC828 , we have the chance of making virtual LANs, that is, VLANs, to make a few nearby subnets and section the traffic lan control systems.
On account of having a further developed home or expert organization, it is totally important to fragment the organization by VLANs, which are essentially virtual LANs, in which the casings are labeled to isolate said subnets, and that we need a switch to have the option to intercommunicate them. VLANs permit us disengagement, better control of all that is going on in the neighborhood organization, and furthermore permit us to have a better and keep away from security issues. That is, for huge organizations where we have countless gear, it is consistently important to section into VLANs to give the organization better security and execution. Moreover, we will likewise have the likelihood to give proficient APs diverse VLANs, and along these lines, have a SSID for each VLAN made.
