Arecibo Coordination Zone

This Report and Order establishes a Coordination Zone that covers the islands of Puerto Rico, Desecheo, Mona, Vieques, and Culebra within the Commonwealth of Puerto Rico (the Puerto Rican Islands). The Coordination Zone requires applicants for new and modified radio facilities in various communications services within the Coordination Zone to provide notification of their proposed operations to the Arecibo Radio Astronomy Observatory (Observatory) near Arecibo, Puerto Rico, and operated by Cornell University (Cornell), at the time their applications are submitted to the Commission. The Coordination Zone and notification procedures will enable the Observatory to receive information needed to assess whether an applicant's proposed operations will cause harmful interference to the Observatory's operations and will promote efficient resolution of problems through coordination between applicants and the Observatory.
