In order to predict the path loss for the two types of scenarios, Mixed Path Model presents two modifications. First, a correction factor for long distances provided for ITU-R P.1546 is added. The second modification is to calculate coefficients for reflection and diffraction for vertical polarization. The results are similar to the measured data used, evidencing the good performance and applicability of the model.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123977203","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}

An influence of a bias point of Mach-Zehnder modulator on scenario of dynamical chaos development is investigated in details. It is shown that increase of a ring gain coefficient leads to changing of generation regimes. A rich set of the generation regimes is observed for the first time. It includes the continuous wave, rectangular periodic pulses, period doubled pulses, period doubled chaotic pulses, chaotic pulses, “weak” chaos, chaos, broadband chaos, and noise. The threshold values of a ring gain coefficient corresponding to changing of the generation regimes are determined. A shifting of the bias point to the maximum of transmission characteristics leads to a consistent disappearance of the regimes.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131565203","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}

Despite the news, there are also some concerns with the legacy automation processes, since industry has lots of data-gathering devices, most of them created and installed a long time before IoT concept emerge. The technology to bring legacy equipment to IoT solutions, indeed, is not totally new, since it involves the use of gateways. IoT gateways bridge devices to the Internet in the context of real-world applications. This paper presents a low cost IoT gateway prototype to bridge conventional Modbus RTU sensors/actuators to a MQTT IoT cloud. The methodology used consists in implementing bidirectional functional mappings between Modbus RTU and a MQTT broker. Two sets of events were defined in this mapping: one for Modbus alerts and other one for MQTT commands. The gateway prototype was validated in a scenario in which IoT Sensors generate events to update a monitor panel controlled by a CLP connected to the prototype. The results were promising since the integration allowed a transparent and efficient operation for the gateway in several different scenarios in the laboratory.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114336751","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}

Finally, the effectiveness of the proposed approach is experimentally assessed through the generation of two pairs of orthogonal SOPs.
