• S-V Model can match measured channels in terms of the population means of Mean Excess Delay, RMS Delay Spread, and Number of Significant Paths for three scenarios:• NLOS, 0 to 4 meters, office• LOS, 0 to 4 meters, office• NLOS, 4 to 6 meters, office
• Variation of measured channels is very wide, even within a single scenario.• A heuristic channel taxonomy is proposed.
• Single set of S-V parameters for each scenario is probably not sufficient to capture the wide variation among channels from a given category.
• Recommendations• channel model should consist of a defined set of channel impulse
response realizations• make sure all channel types within a given scenario are represented
