| 520 | 3 |a"Calculations were made of the minimum separation distance required to permit sharing of the 406.1-410 MHz band by the radio astronomy service and the mobile satellite and land mobile services. Based on assumed characteristics for the systems and using median-path-loss values, this distance was found to vary from about 200 to 500 km, depending on band loading by the mobile services. If interference can be tolerated for less than 50 percent of the time, separations greater than 500 km may be required"--Abstract, page 1. |
