WIFI – stands for (Wireless Fidelity), is commonly used in public places, at home or in a corporate environment. WIFI connects everything with devices that has a wireless adapter and SSID.
There are two types of frequency wifi used for communication, 2.4GHz and 5GHz. Connecting to 2.4GHz means longer range at lower speed while 5GHz, faster speed at shorter range.
For the 2.4GHz band, non-overlapping channel is best and that is 1, 6 and 11 and for the 5GHz choose one of the 24 non-overlapping channels. An overlapping channel could lead to slow WIFI speeds and interference.
SSID (Service Set Identifier), a unique ID that is used to represent wireless connections. SSID can be created in a router, Access Points or in controller-based wifi infrastructure. SSID in a corporate environment usually has a password with encryption mode to protect wireless access, especially for authorized users. On the other hand in public wifi, mostly don’t have a password and it is open.
How to Identify Open and Encrypted WI-FI
Open WI-FI , in the example “test_guest” is the SSID, under it states Open.
Encrypted WI-FI, in the example “Test_wifi” is the SSID, under it states Secured and when connecting to this will ask password.
