Hello, Everyone!
Today, I would like to share briefly with you the earlier Standards of Wi-Fi i.e. Wi-Fi 1, Wi-Fi 2 & Wi-Fi 3.
Note that the WiFi 1, WiFi 2, and WiFi 3 names are not officially recognised and here I am using it just to make it easier to differentiate and to make sense.
WiFi Logo
With the use of an ethernet connection, a local area network (LAN) is utilized to offer connected communication to computing devices. WLAN was created because LAN does not provide wireless communication. WLAN is often referred to as WIFI. A Wi-Fi router is required in order to set up a Wi-Fi network. Wi-Fi routers link one side to a wired broadband connection and deliver wireless signals to wireless devices.
The IEEE has created a set of Wi-Fi standards that cover a variety of speeds, ranges, and frequencies. All the different standards are named as WiFi-1 through WiFi-6 for simplicity

Wi-Fi 1
WiFi 1 refers to the IEEE 802.11b standard. IEEE established the first WiFi standard for Wireless LAN. This WiFi 1 device operates on the 2.4 GHz frequency range and transmits data using the DSSS/CCK modulation methods. It supports various speeds based on the mod-code rate, such as 1, 2, 5.5, and 11 Mbps. WiFi-1 has interior coverage distances of roughly 38 metres and outdoor coverage distances of about 140 metres.
WiFi 2
WiFi 2 refers to the IEEE 802.11a standard. IEEE 802.11b has been superseded by this WiFi standard (i.e. WiFi 1). Unlike wifi-1, which utilised a single carrier modulation method, this is the first wifi standard to employ a multi carrier modulation scheme called OFDM to allow high data speeds. Routers (i.e. APs) and Stations (i.e. clients) based on the WiFi-2 version operate at a 5 GHz RF carrier frequency. Due to the usage of 20 MHz bandwidth, this standard-based device may handle a wide range of speeds or data rates, from 6 to 54 Mbps. WiFi-2 compatible routers have a range of roughly 35 metres (indoors) and 120 metres (outdoors) (in outdoors).
Wi-Fi 3
WiFi 3 refers to the IEEE 802.11g standard. IEEE 802.11a has been superseded by this WiFi standard (i.e. WiFi 2). The WiFi-3, or 11g, standard was created to enable both 11b and 11a standard-based devices in their frequency ranges. It is compatible with the 2.4 GHz and 5 GHz bandwidths. It has all of the features that the 11a and 11b standards have.
Here we have make it easier by naming conversion of WiFi standards from abstract letters 802.11a/b/g/n/ac/ax to numeric ones such as WiFi 1/2/3/4/5/6. In the next post, i will give a brief overview on WiFi 4/5/6
