Wideband and Dynamic Characterization of the 60 GHz Indoor Radio Propagation Future Home WLAN Architectures

This study is part of a RNRT1 project named "COMMINDOR"2. This exploratory project concerns the very high data rate (155 Mbps) and small range (about 10 m) radio communication systems for future home networks, which will permit multimedia equipment interconnection and control. The study is based on several measurement campaigns realized with a channel sounder based on the sliding correlation technique. This channel sounder has a 500 MHz bandwidth and a 2.3 ns effective time resolution. The measurements have been performed in residential furnished environments. The study of the angles-of-arriva (AOA) emphases the importance of openings (such as doors, staircase, etc.) for the radio propagation between adjacent rooms. A particular attention is paid to the infuence of human activity on radio propagation. It is shown that people movements can make the propagation channel unavailable during about one second. From the characterization study of the indoor radio propagation, several recommendations concerning the deployment of the very high data rate 60 GHz wireless networks are derived
