We select a small office as a typical application scenario and carried out extensive measurements with the Vector Network Analyzer (VNA) and frequency extension units in the room. A ray tracing simulator is applied for reproduction of the measurement results and a good match in spatial distribution of prop-agation paths between measurement and simulation is achieved.Purpose: Information of IEEE 802.15 IG THzNotice: This document has been prepared to assist the IEEE P802.15.

Motivation

• The millimeter and sub-millimeter wave communication is a competitive solution to the future multi-Gigabit short range data transmission in femto cell

i tenvironments– Carrier frequencies of 100 GHz and 300 GHz– Bandwidths of several GHz– Data rates of several tens of Gbit/s

• Technology for this application at 90 GHz and 300 GHz is being developed within the European H2020-IBROW-Projekt [2]

• The channel characteristics are crucial for the system development.– Extremely high free space path loss– Different reflection and diffraction characteristicsDifferent reflection and diffraction characteristics– Specular spatial distribution of propagation paths

• This study aims at providing some channel knowledge and comparison of target f i i t ith V t N t k A l (VNA)

Propagation Path Loss (EM Part)• The propagation path losses of different paths from measurement and simulation are

shown.• The antenna gain is subtracted from the raw measurement data.g• The path loss at 300 GHz is as expected higher than at 100 GHz.• Difference between measurement and simulation suggests a further calibration.

Outline





Conclusion

• Channel measurements are done at 100 GHz and 300 GHz with VNA.

• Ray Tracing simulation is carried out to reproduce the measurement results.

• A good match is achieved between measurement and simulation in spatial g pdistribution.

• A calibration of EM parameters is necessary for a better match of propagation path losses.

• The channel at 300 GHz has higher path loss, more serious fast fading and more specular spatial distribution.
