Some of the techniques employed to provide this control are: the extensive use of lead shielding, extra thick steel reinforced concrete walls, and corridor design utilizing short hallways with numerous zigzags, all of which also not being conducive to the propagation of radio-frequency energy. The purpose of this paper is to describe a highly successful and reliable method of providing UHF radio cummunications throughout several radio-frequency isolated buildings. The system to be described will rely on slotted line transmission lines, multiple antennas and full duplex in-line RF power amplifiers. Engineering design considerations discussed will include: theory of operation, intermodulation product concerns, and the selection of commercially available equipment for ease of installation and maintenance.","PeriodicalId":230854,"journal":{"name":"32nd IEEE Vehicular Technology Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117090447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technique has seen limited application, however, due to the requirement of stable microwave audio links to each of the base stations. A system that circumvents this requirement is described. Automatic equalization periodically compensates for changes in amplitude response and phase delay, allowing operation over conventional private lines leased from the telephone company. The system uses these same facilities to synchronize continuous tone-coded subaudible squelch (CTCSS). The simulcast electronics interfaces to the dispatch system through a microcomputer that also controls the signalling subsystems, providing the dispatcher with the ideally simple \"push-to-talk\" operation.","PeriodicalId":230854,"journal":{"name":"32nd IEEE Vehicular Technology Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123582114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
