The control functions for simpler systems are adequately provided by standard remote control units, using options to provide for a variety of needs. More complex systems require special control circuitry and control consoles whose design is part of the overall system design. A duplex backbone system such as used on cross-state turnpikes is typical of such complex systems. Party llne vs. multl-channel design of such systems is contrasted and use of various devices such as receiver voting discussed. Console design is illustrated by discussing features of the Massachusetts Turnpike Control Console. Range of control design is indicated by mention of two-way mobile telephone requirements and the potential field of remote control from portable control consoles, such as remote control of a switching locomotive.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1958-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120948150","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}

Interference problems usually start with the first installation. For about eight or nine years, our companies had varying amounts of interference troubles, and we firmly believed that the thing to do to correct such conditions was to complain loud enough and long enough and the radio vendor would come up with some answers. Each year we had more mobile units, and exposure to interference increased. Channel loading was also increasing, and narrow band sets were getting closer and closer, potentially increasing interference.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"28 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1957-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116632238","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 suppressor design reported was one that provided optimum performance. During the course of the development program, several other types of suppressors were investigated. One type, although slightly inferior in performance to that described, is very attractive because of its simplicity. While it is not satisfactory for use in high gain (10 db) antennas, it is suitable for use in medium gain (4–6 db) antennas, and offers interesting cost reduction possibilities. The design and performance of a 6 db antenna for use in the 450–470 MC band is described.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1957-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124889470","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}

This system would be able to provide mobile telephone service of better quality than at present to many times the present number of customers. This could be made possible by means of an integrated switching and transmission design based upon a broad block of frequencies. All mobile units would be controlled over a data channel from a digital common control system at central. The research, development, and production programs required to bring such a system into being would take a number of years, possibly as many as ten. Technical feasibility seems reasonably certain. To achieve economic feasibility might require a substantial effort. Realization of the system would have to be gradual and would require the cooperation of radio manufacturers, airplane and automobile manufacturers, and telephone companies.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1957-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123990712","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}

Phasing and heterodyne distortion factors in overlap coverage areas must be minimized. After many months of laboratory and field testing, a satisfactory solution has been developed and applied to a system using wire lines for base station and control point interconnection. This method provides precision control of carrier frequencies, and phase equalization of modulation by building out the wire lines so that transit times are equal. After two years of operation this method has proven to assure satisfactory distortion-free reception.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1957-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128383239","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}

In order to gain these advantages, it is necessary to provide an interconnection facility for these many remote stations. Considerable use must also be made of modern high speed switching and common control techniques.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1957-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125918731","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}
