Possible Usage Models for THz Communications <month year> doc.: IEEE 802.15-<doc#> November 2012 Possible Usage Models for THz Communications „Fixed“ THz WLANS with limited beamsteering Server farms In-room multi user WLANS Multi-processor gaming stations 4kx4k TV/in-room entertainment WLANs Business kiosk video download „Mobile“ THz WLANs with full active beamsteering and phase control Pedestrian plazas in buildings Broadband stadium access Automotive [Rail, Airplane] Thomas Kürner (TU Braunschweig) et. al. <author>, <company>

Further Questions to be discussed November 2012 Further Questions to be discussed Are existing 802.15/802.11 (at 60 GHz) MACs are able to carry a THz PHY? Or do we need do look into other MAC-Protocols? Signalling overhead in conjunction with high data rates How does a I/O interface look like? Are there any wireless backhaul issues? Which usage models will inherently avoid interference with passive services? Thomas Kürner (TU Braunschweig) et. al.
