A Survey of Next Generation Gigabit WLAN Standard: IEEE 802.11ac.

With rigorous increases in multimedia stations and applications, wireless infrastructure IEEE 802.11 WLAN standards are widely used. Delivery of excessive concentrated traffic over bequest WLAN standards pretends the functioning by being not simpatico with the resources. Directing to the eminent network throughput, an IEEE WLAN standard has been evolved apprehended as IEEE 802.11ac with ideal data rate up to 1 Gbps. This standard has a capability of using 160 MHz bandwidth, so to utilize it as a whole is always a challenging task due to numerous other standards overlapping the allocated bandwidth. In this survey, we present a brief survey of the IEEE 802.11ac standard with its ancestor IEEE 802.11n standard. Particularly we concentrate on the MAC layer enhancements and the recent invention of the standards. Lastly, we conclude the various authors' innovatory thoughts with their advancements and restriction for acquiring the IEEE 802.11ac standard in ameliorating manner.
