Accommodation of Broadcast Satellite (Sound) and Mobile Satellite Services in the 2300-2450 MHZ Band

摘要

This report provides a feasibility assessment of accommodating the Broadcast Satellite (Sound) Service and a Mobile Satellite Service uplink in the 2300-2450 MHz range. The assessment is based upon measurements by the Institute for Telecommunication Sciences of microwave oven and radio environment characteristics. Projected characteristics of the proposed services are considered. In preparing for the 1992 World Administrative Radio Conference (WARC-92), the United States considered allocating spectrum in the frequency range 2300-2410 MHz to the Broadcast Satellite (Sound) Service (BSS) and allocating spectrum in the frequency range 2390-2450 MHz to a Mobile Satellite Service (MSS) uplink. A concern in implementing these allocations is the operation near 2450 MHz of approximately 80 million microwave ovens in the United States and 200 million worldwide. Therefore, the United States has proposed that 2310-2360 MHz be allocated to BSS and 2390-2430 MHz be allocated to the MSS uplink. The frequency 2450 MHz - 50 MHz is designated for use by industrial, scientific, and medical (ISM) applications. ISM devices use radio frequency (RF) energy for purposes other than communications. Though consumer microwave ovens are not the only ISM devices in this band, they are by far the most prevalent.
