IV.5.4
- Advanced tools and technologies for wireless communication
IV.5.2 - Terrestrial wireless system and networks
IV.2.3 - Network integration, interoperability and inter-working
The objectives will be met by theoretical investigation, simulation and experimental validation for three types of wireless networks, characterised by different requirements on mobility, bit rate, and, partly, types of services:
Outdoor
high bit rate (UMTS-based) networks
Local
and Campus area networks
The
investigation will deal with the classical advantages of introducing smart
antennas: range extension, capacity increase, interference reduction. The impact
on the physical, MAC, link and network layers will be assessed for several types
of traffic, in particular connectionless packet data.
Advanced MIMO (Multi-Input Multi-Output) array diversity techniques, which use array antennas both at the remote and at the base station, will be analysed. An investigation for the synthesis of pertinent access techniques for packet data traffic will be carried out.
The
potential of array processing to provide enhanced location information will be
investigated for UMTS-based outdoor broadband networks.

By
using antenna arrays at both the transmitter and receiver a MIMO fading channel
is created resulting in marked increase in channel capacity.
Array
processing technology will be used to enhance the mobile location function.
Wireless local and campus area networks using HIPERLAN technology will benefit from the use of smart antenna techniques to help mitigate fading and to provide diversity.
