4. Public Service Communications. a. State of California backbone network (law enforcement, management ). b. Law enforcement systems - state, county, city - mobile, relay, and base station equipment. c. Forest service units. d. Fire and government emergency systems - county and city operations . e. Common carrier networks - telephone, data, television services - remote area voice links. 5. Specialized Services a. Space tracking and monitoring facilities (Goldstone area), b. Railroad hump radars. These system categories are in the frequency range cited for the file retrieval and are susceptible to SPS power densities previously displayed. The quantitive functional degradation induced into particular major equipment categories deployed near the candidate Mojave site is indicated in Table 4.7. The derivatives of these performance factors are presented in the Mojave evaluation report.* Those functional systems included represent high priority operations that encompass relatively large geographic areas around the periphery of the rectenna site. The percentages indicate the characteristic changes for the various systems because of SPS illumination. Various railroad, lav; enforcement, and emergency communication services will be incorporated into the functional categories as soon as degradation analysis is completed. The equipment presently uses very high frequency (VHF) and UHF analog voice or low data rate modes, and will therefore be minimally affected. Relays and base stations for these services could be readily modified where necessary by shielding and antenna pattern adjustments. Common carrier links will also be scored for future assessment analysis. These will include relays and mode stations. The elements of performance degradation cited for the functional systems represent average overall operating modes and geographic range. For example, instrumentation radar systems detection and tracking performance includes operation over a full hemisphere coverage, and the range of cross section magnitudes for military target vehicles (e.g., tactical fighter *SPS EMC Evaluation - Mojave Rectenna Site, DOE report (to be published).
