The Government of Indonesia through PERMENKOMINFO number 25 in 2014 allow the use of frequency sharing between the Fixed Satellite Service and Fixed Service in extended C-Band frequency. Frequency sharing conditions can lead to potential interference so both services need a good coordination so that both services can operate properly. In this study conducted a simulation of frequency sharing between the FSS and the FS in the extended C-Band frequecy using software SPECTRAemc. Found cases of interference in the area of South Lampung involving an FSS station transmitter and several receivers FS stations that being around. The parameters used to evaluate the level of interference at the receiving station is a carrier-to-interference (C/I) parameter. Then it is necessary to find appropriate mitigation techniques to reduce the level of interference. Mitigation techniques done by changing the position of the earth station of the starting position so that it can be determined the minimum mitigation distance of the earth station. Then do also some changes in both parameters of the earth station and the terrestrial station to obtain a value of C/I above the threshold. From the simulation using software SPECTRAemc result that FSS stations and FSS stations can operate without disturbing each other when the FSS station moved as far minimum 7,21 km from its original position towards 213.56° azimuth. Besides, it is necessary to change the antenna polarization FSS stations to isolate the interference signal at the receiving antenna and the FS statiosn is necessary to increase the transmit power of the FS transmitter station to increase the value of C/I.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125260313","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}

It contains valuable information for many purposes of several domains such as billing, fraud detection and analytical purposes. However, in the real world, these needs face a big data challenge. Billions CDRs are generated every day and the processing systems are expected to deliver results in a timely manner. In our case, the system also has constraint that is running in limited computation resources. We found that our current production system was not enough to meet these needs. We had successfully analyzed the current system bottleneck and found the root cause. Based on this analysis, we designed and implemented a better performance system which is based on MapReduce and running on Hadoop cluster. This paper presents the analysis of previous system and the design and implementation of new system, called MS2. In this paper, we also provide empirical evidence demonstrating the efficiency and linearity of MS2. In a test case of telecommunication mediation system, our test has shown that MS2 reduces overhead by 44% and speedup performance by nearly twice compared to previous system. From benchmarking with several related technologies in large scale data processing, MS2 is also shown to perform better in case of CDR batch processing. Running on a cluster consists of eight core CPU and two conventional disks, MS2 is able to process 67,000 CDRs/second.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134130813","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}

By using it, the organization is able to collect, process, and provide data faster, share knowledge, enforce their employee to communicate and collaborate with any devices. Digital workplace can be enabled by implementing many recent technologies such as big data, cloud computing, search-based application, and internet connection. But in this paper, we argue that technology is not enough to help the organization to do its business and reach its goal. According to these arguments, we propose the conceptual framework of digital workplace diffusion. This conceptual framework integrates diffusion theory, user's engagement, and controls. Controls are contained IT governance, risk management, compliance. We believe that user engagement and control are one of the keys for successful digital workplace diffusion. User engagement measurement is able to show the degree of employees' understanding and acceptance to the digital workplace. Meanwhile, control is used to help the organization in managing, monitoring, ensuring the digital workplace is aligned to the requirements and regulations.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123331083","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}
