Distributions of delay spread and correlation bandwidth at 0. 9 and 0. 5 correlation for Gaussian wide-sense stationary uncorrelated scattering (GWSSUS) channels associated with 100 small-scale areas at different locations within a 2 × 2. 5 km region of New York City are presented. For delay spread the maximum value observed was 312; s and l0 percent of the areas exceeded 212 s; for correlation bandwidth at 0. 9 correlation the minimum was 20 kHz and 10 percent of the areas were less than 30 kHz; for correlation bandwidth at 0. 5 correlation the minimum was 55 kHz and 10 percent of the areas were less than 130 kHz. The region is representative of the heavily built-up areas of many large cities in the United States.
