Abstract

In response to a petition, the Commission proposes the reallocation of forty-eight 25 kHz channels in the 928-929 and 952-960 MHz band segments to the Private Operational-Fixed Microwave Service and the Domestic Public Land Mobile Radio Service for distribution automation and wide-area control and repeater operations, respectively. The spectrum from 928 to 929 MHz is presently reserved for Land Mobile. The 952-950 MHz band is currently allocated to the Private Operational-Fixed Microwave Service and the International Control Services.

摘要

应一份请愿书的要求，委员会提议将928 - 929 MHz和952 - 960 MHz频段中的48个25 kHz信道重新分配给专用运营固定微波服务和国内公共陆地移动无线电服务，分别用于配电自动化和广域控制及中继器操作。928至929 MHz的频谱目前保留给陆地移动使用。952 - 950 MHz频段目前分配给专用运营固定微波服务和国际控制服务。
