Research output: Contribution to journalArticlepeer-review


This letter describes multipath power delay profile measurements of 900 MHz mobile radio channels in four US cities. Preliminary data show that for over 98% of the measured locations, RMS delay spreads are less than 12 fxs. In very rare instances, reflections from city skylines and mountains can cause RMS delay spreads which exceed 20/is and excess delays which exceed 100 fis. Such large excess delays have not been previously reported in the literature.
