520 The need for higher data rates in WLANs boosts drastically
because tremendous consumer interest in emerging
multimedia applications, such as HDTV, has been increased.
Currently, the IEEE 802.11a/b/g WLANs provide a limited
data rate for the current user application requirements.
In order to overcome substantial limitations of the
existing WLANs, the next generation of WLANs, IEEE 802.11n,
is in the course of development and expected to support
higher throughput, larger coverage area and better QoS.
The high performance IEEE 802.11n WLAN can improve data
rate significantly by using smart antenna systems in the
physical layer to take advantage of multi-path fading of
wireless channels
520 In this thesis, an analytical model is developed to study
the MAC performance and the underlying smart antenna
technologies used in multi-path fading channels. Multiple
antennas employed in the AP arise two popular approaches
to provide a significant performance improvement,
diversity and multiplexing. Considering the diversity gain
of multiple antennas at the AP in which the AP with
multiple antennas serves one user at a time, the capacity
and throughput can be obtained. In addition, the AP is
possible to serve multiple users in the downlink, by
exploiting the multiplexing gain of the wireless channel.
We investigate the maximum network throughput when the
traffic intensity of the AP approaches to one. Unlike most
of previous research which focus on either the physical or
the MAC layer performance, our analytical model jointly
considers the MAC protocol and the smart antenna
technology
