One key factor influencing the coverage in mobile networks is related to the configuration of antennas and especially the antenna tilt setting. The power of the received useful signal in a cell can be increased with proper antenna tilt, causing a significant improvement in signal-to-interference-plus-noise ratio (SINR) which also leads to reduction of interference towards other cells. Dynamic antenna tilt optimization is even more important for the next fifth generation (5G) of wireless communications especially in ultra-dense scenarios for the provision of sufficient coverage and quality of service (QoS). In this work, the effect of wireless channel model selection for the goal of self-optimization of the base station (BS) antenna electrical tilt is investigated. A comparative analysis of the application of different propagation models is performed using an existing method for dynamic and adaptive tilt adjustment based on reinforcement learning (RL) methodology. Simulation experiments considering a cellular network with multiple cells in an urban scenario with randomly distributed users have been carried out and the achieved results show that the careful choice of channel model and related parameters is crucial for the antenna tilt self-optimization process.","PeriodicalId":256742,"journal":{"name":"2018 Global Wireless Summit (GWS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116566546","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 ultra wideband (UWB) technology is suitable for BAN system because of transmission by impulse radio and low power. However, signal distortion due to human body effect in human body-ultrawide band (HB-UWB) channel must be study. In this study, we evaluate HB-UWB channel which serious disturbed by the distortion. The distortion can cause extremely poor signal quality to wireless transmission channel even in free space because of the antenna characteristics and waveform distortion. Thus, the understanding of the effect from characterization of antenna and waveform effect is important. The measurement data of distortion analysis due the antenna and human body of HB-UWB for WBAN were presented in this research report. The receiver waveform template was present to maximize system signal to noise ration. The equation of Friis had been used to evaluate the results. The proposed method is practical for the HB-UWB evaluation, UWB antenna design, and provide more precision to identify the waveform distortion.

A virtual colloquial associate helps making the lives of people easier by performing the routine tasks that a user has to perform. It thus saves time for the user and makes the users life efficient and more Productive with controlled consciousness.

In teaching, the process can start from preparing the teaching materials, teaching activities, communicating with students and evaluating student knowledge level. Digital technology can be used to improve and facilitate each stage of this teaching process. However, effectively selecting digital tools for used in each stage can be difficult for teachers especially the ones in non-IT field due to the knowledge of the digital tools, lacking digital skill as well as the limited experiences on how to use them in teaching activities. In many countries, their ministry of education has been providing digital tools and many trainings trying to help teachers to effectively utilize digital tools in their teaching activities; however, the tool selection and the training approach that were used still not effective enough that the tools were used effectively and non-productively in teaching process. This paper reports the result of the developing digital skill for teachers and how they can use digital tools in teaching activities or process. This report is also one part of the major research project supported by the National Broadcasting and Telecommunication Commission (NBTC) of Thailand. The digital tools were collaboratively selected by teachers in the project then trained by researcher team. The tool utilizations in teaching activities are designed, implemented and concluded by community of teachers in the project.","PeriodicalId":256742,"journal":{"name":"2018 Global Wireless Summit (GWS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116045109","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 represents the main cause of death worldwide. Accordingly, preventing aged people from CVD has been extremely considered nowadays. The aim of this study is to determine proper recommendations to the elderly who have high risks of CVD complication for preventing themselves. Therefore, this paper applies the concept of an objective distance which is a measurement used as the indicator for recommendations. It defines the distance between the current status of the elderly people and objective level of each attribute for deriving the proper recommendations. Significantly, this distance provides the effective direction for their personal lifestyle adjustment. An experiment is performed in the context of hypertension, which is one of the main risk factors of CVDs. Data is gathered from 60 elderly people who are at the high risk of CVD in Chiang Rai, Thailand. A result of this experiment presents that the proposed objective distance can be efficiently employed for providing the appropriate recommendations to each elderly person. Also, they successfully modified their lifestyle behaviors for protecting themselves from CVDs, accounted for 90 percent accuracy.","PeriodicalId":256742,"journal":{"name":"2018 Global Wireless Summit (GWS)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128846861","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}
