802.11ac is a fifth generation WLAN standard. The transfer speed of this standard is three times higher than the speed of its predecessor and is at the same time much faster than the standard that emerged in 1997. Its security is improved, and both the capacity and the range of this standard are significantly enlarged. Those features play a key role in its quality improvement. Its speed reaches up to 1Gbps, enabling high bandwidth transfer on multiple devices at the same time. The 5GHz channel reduces the number of errors. There is large number of wireless devices that broadcast equivalent omnidirectional signals but when using the 802.11ac standard there is an option to find the location of the broadcasting device in the network. Using this option, the sender can locate and send the packages directly to the device which is connected to the Internet and that is the reason why the signal is stronger, clearer and three times faster. The aim of this research would be to analyze all characteristics mentioned above and their practical implementation in a device that uses 802.11ac standard. The need for speed of a wireless network is always insatiable. The first standard that appeared fifteen years ago provided speeds of 1 Mbps and 2 Mbps to be used in office buildings where mobility was not a requirement [5]. The first Wi-Fi device was introduced in 1997. For the first time the users were unrestricted with a physical connection and could move freely while they accessed the
