A novel approach will be used to find a way to use upcoming transmission standards to build a multi-gigabit rotary transmitter. Channel models of a so-called multi-mode wave orbit were developed to determine and optimize the key characteristics of the novel channel. A test setup has been used to measure the channel and compare it to the model. It could be shown that with the help of several optimizations, a channel can be created that provides a stable channel capacity of over 10 Gbps at a bandwidth of 1.76 GHz for diameters of 1.1m at over 100 rpm. Due to the simple construction and the possibility to use off-the-shelf components, this approach becomes interesting for a variety of rotary transmitter applications.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128779160","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}

To minimize the loss, deep learning techniques are utilized to detect leaf infection and have wildly outperformed the traditional method of manual detection. However, deploying such models is a challenge since devices in the field normally have limited resources and low computational power while large datasets have to be used. Therefore, in this paper, we benchmark the most popular deep learning models for multi-leaf disease detection to gauge which model is the most suitable for real deployment. Using a real-world large-scale dataset from PlantVillage and a Raspberry Pi 3, we found that MobileNet V3 provides a reliable accuracy of 96.58%, small Inference/Initialization time of 127 ms and 11 ms respectively, requires only 7.4 MB of memory in total, and hence the most appropriate choice for a real farm.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124732876","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}

Once a server received a confirmed message from an end device, it responds with an acknowledgement message to make sure that the uplink message was successfully delivered. For doing this, the protocol reserves two receive windows that follows uplink message transmission in the specified intervals. However, when GW responds with an acknowledgement message in one of the receive windows, it fails to receive messages from other end devices since it operates in half-duplex mode. This can cause high data loss as the number of confirmed messages increases. In this paper, we study how the increase of confirmed messages and message traffic affects packet delivery ratio. The simulation results shown that up to 24% number of uplink messages is lost or collided when 1000 end devices transmit data with 0.1% duty cycle and the confirmed message ratio is 0.2.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126529999","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 design includes a horizontally polarized (HP) dipole array and a vertically polarized (VP) monopole antenna. The dipole array is excited by a feeding network with an in-phase 1:4 power divider to achieve omnidirectional radiation in the horizontal plane. Each HP element is fed by an out-of-phase power divider for improving polarization purity, and consequently, achieving a high isolation. The final design yields an overlapped impedance bandwidth of 48.08% (3.27 – 5.34 GHz), a port-to-port isolation of >40 dB, and satisfactory conical patterns in both modes. With the features of wideband, conical pattern, high isolation, the proposed antenna is a good candidate for indoor access point in the IBFD systems.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128394228","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}

This paper focuses on evaluating the performances of these VPN technologies integrated into the operating system for routers.

In this paper, design and implementation of a small-size WiFi-based prototype of a V2V-V2I communication unit for low speed vehicles is presented. WiFi, a popular wireless communication technique, was chosen since it is not only a cost-effective choice, but it is also suited for low-speed vehicles like motorbikes, bikes, tracking UAVs, and ground robots.
