Introduction

Under the Radio Regulations, as revised by the World Administrative Radio Conference, Geneva, 1979, the broadcasting-satellite service has allocations, or is permitted to operate, under certain conditions in the following bands, all shared with other services:

— 620 to 790 MHz, which is mainly used by the fixed, mobile, and terrestrial broadcasting services; 2500 to 2690 MHz to be shared with the fixed, mobile, broadcasting and fixed-satellite services;

— 11.7 to 12.5 GHz in Region I to be shared with the fixed and broadcasting services on a primary basis (and with the mobile service on a secondary basis);

— 11.7 to 12.2 GHz in Region 3 where it is to be shared with the fixed, mobile and broadcasting services;

— 12.2 to 12.70 G Hz in Region 2, shared with the fixed, mobile and broadcasting services;

— 12.5 to 12.75 GHz in Region 3 shared with the fixed, mobile and fixed-satellite services;

— 22.5 to 23 GHz in Regions 2 and 3, where it is to be shared with the fixed and mobile services (and, in the upper 0.45 GHz of that band, with the inter-satellite service);

— 40.5 to 42.5 GHz to be shared with the broadcasting service on a permitted basis; and

— 84 to 86 GHz to be shared with the fixed, mobile, and broadcasting services, except that these services cannot cause harmful interference to broadcasting-satellite earth stations operating in accordance with a plan yet to be adopted by a subsequent Administrative Radio Conference.
