What is Wi-Fi?
Wi-Fi is a Wireless Local Area Network technology that gives short-coverage wireless data connections between mobile data gadgets like laptops and phones
The old variation of Wi-Fi, 802.11g, is fit for providing paces of up to 54Mbps and is in reverse good with 802.11b (providing up to 11Mbps).
The later standard is called 802.11n (offering rates of up to 150Mbps per channel or up to 600Mbps in all out). It very well may be used in the 2.4 GHz or 5 GHz frequency bands; however, a collector needs double band receiving wire to work on both.
