High Speed Wireless Data Transmission in 6-9 GHz Band (HiWi)

Project Goal

The project is aimed to study and develop an innovative technology for future high speed wireless data transmissions at 10 Gbps in short range (~10 meters). The project is based on the principle of frequency multiplexing and the Six-port transceiver architecture. The technology to be developed has characteristics of simplicity, flexibility, and short time-to-market. A few demonstrators will be implemented to show possible applications.

Background

The research front for short range wireless data communication is spot-lighted by the UWB development, since FCC in USA released the frequency band 3.1-10.6 GHz (7.5 GHz total bandwidth). However, the data rate has been limited to 0.48 Gbps, and only the so-called Mode 1 sub-band between 3.1-4.8 GHz is utilized today. Recently, a downlink speed of 2.5 Gbps utilizing the Multiple Input Multiple Output (MIMO) technique has been reported. However, future data transmission applications may require tens of Gbps. It will be very interesting to have a technology for transmitting such very high speed data using a short-range wireless data transmission technique. Wireless data transmission has its advantages of low link loss, flexibility and potentially lower cost than wired solutions. This project focuses in the frequency band 6-9 GHz which has been specified for the UWB technology in Europe.
