The most significant advantage of SCM in optical communications is its ability to place different optical carriers together closely. On the other hand, Wavelength Division Multiplexing (WDM) is a multiplexer at the transmitter to join the signals together, and a demultiplexer at the receiver to split them apart. In WDM each laser is modulated at a given speed, and the total aggregate capacity being transmitted along the high-bandwidth fiber is the sum total of the bit rates of the individual lasers. In this work, we investigate various issues in this scenario in order to provide a cost-effective, high performance solution for high speed data rates by the available bandwidth of the electrical and optical components. Therefore, SCM must be used in conjunction with WDM to utilize any significant fraction of the fiber bandwidth. The results is present higher bandwidth for long distance communication system (SMF, 150 km) by using SCM/WDM for Radio over Fiber. Therefore, the efficiency of bandwidth utilization of SCM is expected to be much better than conventional optical WDM.","PeriodicalId":329128,"journal":{"name":"2008 IEEE International RF and Microwave Conference","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128002086","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}

Research has shown that factors such as temperature, humidity, liquid, phase and gas compositions, are critical in producing quality clonal materials using tissue culture process. Therefore, it is necessary to provide good physical and chemical conditions for production of quality products. Consequently, sensors are required to monitor and record the data in growth room. All sensors will monitor critical parameters that focus on temperature, humidity, oxygen, carbon dioxide, ethylene and also an optical sensor for liquid phase and composition that will be linked to the database and analysis software for storing and analyzing the monitored data. The integrated sensors are low cost because it used local products and low power consumption and fabricated to suit the biological laboratory environment. The purpose of these integrated biotechnology sensors system is to serve as an interface among user, as the disturbance analysis program and an expert system in identifying the disturbance. The system would monitor via a smart RFID telemetry system and provide automatically email or short message (SMS) notifications upon identification of a disturbance module. Radio-frequency identification (RFID) is an automatic wireless identification method using radio waves, relying on storing and remotely retrieving data from integrated sensors using devices called RFID tags or transponders. Some tags can be read from several meters away and beyond the line of sight of the reader which make easier for data transportation. For the best communication path, active RFID tags will be equipped with autonomous networking; which greatly improves the utility of the device. Eventually, this smart RFID technology system could improve the efficiency of inventory tracking and management for oil palm tissue culture growth.","PeriodicalId":329128,"journal":{"name":"2008 IEEE International RF and Microwave Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126695984","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}
