Abstract
Wireless LAN has enjoyed a growing popularity
in the past two years due to its unlicensed, low-cost
and high-rate nature compared to cellular networks.
This success has triggered a change in the end-user
demand toward high quality, rate-hungry multimedia
applications such as wireless high definition digital
videos and games. As a result, the current 2.4 GHz
and 5 GHz wireless LAN bands are becoming
inadequate to fulfill the demand, partly due to
insufficient bandwidth, but also due to the inefficient
MAC protocols that are being used in the current
wireless LAN. In view of this, in this group project,
we investigate the possibility of deploying wireless
LANs with wideband transmission in the 60 GHz
band where ample unlicensed bandwidth is available.
In addition, as the short wavelength at 60 GHz
implies both compact multiple-antenna deployment
and high spatial diversity within a small area, we also
consider MIMO transmission techniques as a wireless
LAN depends on the characteristics of the channel it
is being applied to, the physical layer transceiver
design, antenna design, and the MAC protocols. As
such, this group project relies on the following three
projects to cover all these performance-defining
factors, in order to gain preliminary but
comprehensive insights into the design of a wideband
wireless LAN.
Subproject 1: WLAN Channel Characteristics
Measurement, Analysis, and Simulation
at 60GHz
Subproject 2: High Speed Baseband Multi-Antenna

This is the first year of the group project, and this
report summarizes the research outcomes of each
subproject in this year.
