Background TGad Channel model development procedure [1]
Jan 2010 Background TGad Channel model development procedure [1] Statistics for a single link for a given environment Each instance generated from the developed channel model determines LOS and reflected paths between two devices Does not capture statistics of the channels between two independent links 1. Define environment 2. Collect statistics of temporal and spatial (AoA, AoD) characteristics of - LOS - 1st - order reflected paths - 2nd - order reflected paths 3. Curve fit collected statistics with approximation temporal spatial Minyoung Park, Intel Corp.

Jan 2010 Example All the channels are generated from the channel model independently and does not capture the relative location between two links AoA and AoD generated by the channel model independently from link-1 and link-2 Conference room boundary AoA generated by the channel model LOS Interfering link Reflected path Reflected path LOS LOS Reflected path Reflected path AoA and AoD generated by the channel model independently from link-1 AoD generated by the channel model Link-1 Link-2 Minyoung Park, Intel Corp.

TGad Evaluation Methodology (EVM)
Jan 2010 TGad Evaluation Methodology (EVM) TGad EVM defines three scenarios Conference room 8 STAs + 1 AP fixed locations Living room single link (TV – STB, 3m separation) Enterprise cubicle 3 STAs in each cube + 1 AP STAs have random (x,y) and fixed z; AP has fixed location Minyoung Park, Intel Corp.

Proposed approach - conference room scenario
Jan 2010 Proposed approach - conference room scenario Conference room scenario Generate a set of channel realizations with inter-cluster parameters for all possible links defined in the scenario with ray-tracing Total number of channel instances: Link-n Channel realization table A fixed set of channel realizations with inter-cluster parameters 1 Read the channel between a pair of devices from the table 2 Block part of clusters + human blockage 3 4 Generate intra-cluster parameters Apply antenna model and beamforming 5 Calculate received signal power 6 Signal power Link-n Static Dynamic Minyoung Park, Intel Corp.

Proposed approach - home living room scenario
Jan 2010 Proposed approach - home living room scenario Home living room scenario Only one link Use the developed living room channel model 1 Generate all possible clusters and inter-cluster parameters Block part of clusters + human blockage 2 3 Generate intra-cluster parameters 4 Apply antenna model and beamforming Calculate received signal power 5 Signal power Minyoung Park, Intel Corp.

Proposed approach - enterprise cubicle scenario
Jan 2010 Proposed approach - enterprise cubicle scenario HDD monitor laptop Link-n AP Enterprise cubicle Fixed locations for all the devices Fixed channel allocation Generate a set of channel realizations with inter-cluster parameters for all possible links defined in the scenario with ray-tracing Total number of channel realizations: links between STAs in the cubicles + links between laptops and AP in the ceiling = Channel realization table A fixed set of channel realizations with inter-cluster parameters 1 2 Read the channel between a pair of devices from the table Block part of clusters + human blockage 3 4 Generate intra-cluster parameters 5 Apply antenna model and beamforming Calculate received signal power 6 Signal power Link-n Minyoung Park, Intel Corp.

Proposed STA locations within each cubicle and channel allocation
Jan 2010 Proposed STA locations within each cubicle and channel allocation STA locations (x,y,z) in meters measured from the reference point per cubicle STA1 (monitor) =(0.5,0.5,1.0) STA2 (laptop) =(1.0,0.25,1.0) STA3 (HDD) =(0.25,1.0,1.0) Channel allocation Cubicle 1, Cubicle 2, and Cubicle 5 use the same channel STA3 STA2 STA1 Reference point Minyoung Park, Intel Corp.
