The phenomenon it describes has had an amazing impact on electronics over the last few decades, continually making devices cheaper, faster and smaller. Moore's law is an example of prediction about technological growth - it is not founded in laws of nature, like Ohm's Law, for example, but is essentially an economic prediction based on observations of previous trends in scientific research and industry. In this article, we take a look at a range of such laws or predictions, in particular those with relevance to communications technology understanding where they have come from and what their impact might be in the future.","PeriodicalId":371133,"journal":{"name":"Communications Engineer","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128889501","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 upward march of computer clock frequencies and the massive deployment of radio users of these frequencies have fueled this concern. There has always been difficulties in dealing with physically large equipments and the need to establish testing of everyday electronics above 1 GHz has brought objects into the \"large compared with a wavelength\" category. In this paper, the author discussed the increasing importance of electromagnetic compatibility at higher frequencies. All the presented discussions apply to the traditional \"open area test site\" which has been adopted by CISPR. At the seminar, opinions were divided on the wisdom of CISPR's choice of traditional test methods.","PeriodicalId":371133,"journal":{"name":"Communications Engineer","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122366874","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 wireless revolution that started with the first broadcasts, continued with cellular telephony, exploded with WiFi and is now ready to invade every aspect of human life. In this paper, the author examines the prospects for wireless mesh networking. The article details the network infrastructure, wireless cities, and the single, dual, or multi-radio configuration. The prospects of both WiMAX and wireless mesh equipment coexisting in the same place, at the same time, and to perform more or less the same function might have been ludicrous only five years ago, but then again, no one can really accuse the wireless industry of lacking ideas when it comes to getting to that elusive last mile.","PeriodicalId":371133,"journal":{"name":"Communications Engineer","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131187572","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}

Although the receiver on Cassini captured and correctly interpreted data during tests in which both the Huygens space probe and the Cassini spacecraft would maintain the same relative position, there was substantial data loss when the tests simulated the craft's planned trajectories. Subsequently, additional in-orbit performance mappings could only ascertain the receiver deficiency. An analytical model of the receiver's symbol synchronizer was developed. In addition to explaining the dynamics of cycle slips in the symbol synchronizer, the model provided the Task Force with the remaining operational corridor of the receiver. This combined information formed the crucial basis for evaluating possible recovery scenarios by radically revising the orbiter/probe relative geometry.","PeriodicalId":371133,"journal":{"name":"Communications Engineer","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129596584","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}

While Cingular's position has improved over the last few years with its acquisition of AT&T, reports show Verizon consistently outperforming the market every quarter in the critical areas of customer loyalty and underlying strength. Cingular, however, believes it can stay ahead of the competition by bringing the wireline broadband experience to the mobile market. To achieve this goal, the company has begun a comprehensive upgrading of its entire network. The company is also working on acquiring technology that could allow customers to view brief segments of live television programming.","PeriodicalId":371133,"journal":{"name":"Communications Engineer","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125195877","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 idea for cognitive radio has risen from the need to utilise the radio spectrum more efficiently, and to be able to maintain the most effective form of communication for the prevailing conditions. By using intelligence built into a radio, it will be possible to look at the spectrum, detect which frequencies are clear, and then implement the best form of communication for the prevailing conditions. In this way cognitive radio is able to select the frequency band, the type of modulation, and power levels most suited to the conditions and the application. Although the basic idea for cognitive radio is fairly straightforward, the practical implementation poses many problems. As a result, work is progressing to investigate the best methods of achieving a workable system.","PeriodicalId":371133,"journal":{"name":"Communications Engineer","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133096839","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}
