Wi-Fi 1
The 802.11b WiFi Standard, also known as "WiFi 1", was adopted in September 1999 and operated on a 2.4 GHz frequency band. The standard offers a maximum theoretical bandwidth of 11 Mbps, although in practice, the actual data transfer speed is typically less than 6 Mbps. The 802.11b standard utilises CCK and DSSS modulation to improve speeds. However, it is susceptible to interference from other devices operating on the same frequency, such as microwave ovens and cordless phones. This standard has a range of approximately 35 metres indoors and 140 metres outdoors, depending on environmental conditions.
