The 4.9 GHz Band Transferred from Federal Government Use
Lokale automatische Übersetzung · Originalsprache der Quelle
Zusammenfassung
In this document the Federal Communications Commission (FCC) denies petitions for reconsideration of the FCC's decision to prohibit aeronautical mobile operations in the 4940-4990 MHz (4.9 GHz) band. While the FCC believes that it could fashion no general rule that would adequately protect radio astronomy operations without being so restrictive as to limit the utility of pursuing aeronautical mobile operations in the 4.9 GHz band, the FCC nonetheless recognizes the public safety community's interest in utilizing the 4.9 GHz band for aeronautical mobile operations. Thus, the FCC provides a mechanism whereby such operations could be allowed on a case-by-case basis provided that there is a sufficient technical showing made that the proposed operations would not interfere with in-band and adjacent band radio astronomy operations.
