Modern wireless technologies - 802.11n
 Bednář, František ; Molnár, Karol (referee) ; Skořepa, Michal (advisor)
This work describes new standard 802.11n for wireless network. The work contains two parts: theoretical and practical. Theoretical knowledge and understanding our problems will be used in design and simulation wireless network. Theoretical part will discuss about function and methods, which the standard picking over from older standard 802.11a, 802.11g a about new features, that should raise transmission data rate and throughput on MAC sublayer dramatically. Data rate of networks based on standard 802.11n will be comparable with Ethernet networks. Main features that increase data rate on PHY layer is method of multiple antennas calls MIMO and use 40 Mhz channel. On MAC layer will be add frame aggregation that cause linear dependent of throughput on MAC layer and data rate on PHY layer. In practical part we will pay attention simulation of stream video high definition in wireless network. This part contain design and components configuration in network. We will be able to compare simulation results individual standards, by creation of several duplicate scenarios.
