This part of the course
contains three short videos to help understanding oof
the radio propagation. The first viedo shows
the characteristics of the radio channel in tiome and
frequency domain using a network analyzer. The second video show
statistical channel modeling results using PROPSIM
channel simulator. The last video provides a short description of Ray
Tracing software. This section also provides an audio intervieo
with a CEO of a samll start up company designing
wireless LANs. To see the audio visual support click here .
In this course the main principles of wireless
broadband and ad-hoc local area networks (LAN) and their practical
implementation are presented. The basic concepts of LANs.
Radio channel characteristics in wireless LAN application
environment such as home, office and industrial premises. Unlicensed ISM
and UNII- frequency bands for WLAN applications.Examples
of broadband and ad-hoc local wireless networks: IEEE 802.011, HIPERLAN, and
Bluetooth. Future trends of WLAN industry: higher data transmission speed,
ad-hoc operation, integration of WLANs and mobile
cellular networks.The tentative daily syllabus is:
