International Conference on Telecommunication, electronic and Computer engineering 2019, ICTEC 2019

作者： Suryanegara, Muhammad Graduate Program in Telecommunications Management Department of Electrical Engineering Depok Universitas Indonesia Indonesia

The way 5G operators manage infrastructure, enterprise and customers will be radically different compared to preceding generations. This paper aims to provide new perspectives on the 5G operating model by presenting a visual guide on how mobile network operators should deliver value to their prospective 5G customers. The model presented enriches the eTOM framework by elaborating on the implications of virtual network operations, the consequences of an mmWave band, the value of the non-human customer, the security concerns, the role of the content provider in a new ecosystem, and the anticipation of the next generation technological platform. © 2020 IOP Publishing Ltd.

This paper aims to identify what new features need to be improved in the IoT services implemented in the Jakarta Smart City platform. We use sequential steps to construct the Kano Model and first define 10 attributes representing features as recommended improvements for the future IoT. The relevant survey was conducted among institutional users of the IoT services under the platform of the Jakarta Smart City. The findings show that 2 attributes fall into the category of Must Be, which are strongly expected by the users. These are the features that improve working productivity and efficiency and those that guarantee security and privacy. The rest of the attributes fall into the category of Indifferent, which users do not consider as significantly affecting their satisfaction in the future. © 2020 IEEE.

Due to the particularity and complexity of the underwater environment, the perception ability of Autonomous Underwater Vehicles (AUVs) has become a hot issue in recent years. In this paper, the detection system was developed for bioinspired Spherical Underwater Robots (SURs) based on the pressure sensor array. Firstly, the sensor array based on the SUR model was proposed using pressure sensors, adding new dimension to near-flow detection and perception method. Then, the detection system was constructed and the hydrodynamic pressure variables are analyzed. Next, the data acquisition of the pressure sensor array was described. Furthermore, the SUR prototype was assembled carrying the pressure sensor array. Finally, a series of locomotion experiments were performed to verify its performance. The experimental results validated the effectiveness of the proposed detection system, which had a certain reference value for AUV underwater detection and state estimation.

Relying only on behaviors that emerge from simple responsive controllers; swarms of robots have been shown capable of autonomously aggregate themselves or objects into clusters without any form of communication. We push these controllers to the limit, requiring robots to sort themselves or objects into different clusters. Based on a responsive controller that maps the current reading of a line-of-sight sensor to a pair of speeds for the robots' differential wheels, we demonstrate how multiple tasks instances can be accomplished by a robotic swarm. Using the dividing rectangles approach and physics simulation, a training step optimizes the parameters of the controller guided by a fitness function. We conducted a series of systematic trials in physics-based simulation and evaluate the performance in terms of dispersion and the ratio of clustered robots/objects. Across 20 trials where 30 robots cluster themselves into 3 groups, an average of 99.83% of them were correctly clustered into their group after 300 s. Across 50 trials where 15 robots cluster 30 objects into 3 groups, an average of 61.20%, 82.87%, and 97.73% of objects were correctly clustered into their group after 600 s, 900 s, and 1800 s, respectively. The object cluster behavior scales well while the aggregation does not, the latter due to the requirement of control tuning based on the number of robots.

Before implementing 5G technology, each operator first needs to know their existing network capability. The operator's network must be able to meet the stringent 5G network requirements, including a very low latency, especially for the URLLC (Ultra Reliable Low Latency Communication) scenario. This scenario requires 1 ms latency for applications to run smoothly. In this paper, we use a case study from one of the operators in Indonesia to obtain measurements of the network, evaluate it, and then develop strategic steps that will allow the operator to determine whether the network can implement 5G URLLC. A correlation is observed between the latency and the distance from the site to the data center in the operator's network in Indonesia. The maximum site to data center distance to achieve 1 ms latency is 21.4 km using the existing 4G network infrastructure. We also discuss the optimum design for a new data center location and an efficient schema for building new 5G infrastructure. © 2020 IEEE.

Recent studies on modern wireless communication systems are focusing on Massive Multiple- Input Multiple-Output (MIMO) technology for its high potential. MIMO systems require high resolution Analog-to- Digital Converters (ADCs) in the Base Stations (BS) to reduce quantization noise. However, using high resolution ADCs causes higher power consumption at the BS and the hardware costs increase. Reducing the resolution of the ADCs at the BS causes severe non-linearity errors due to additional quantization noise. In other words, MIMO systems cannot achieve high performance without highly linear and low resolution ADCs. In this paper, a 3-bit highly linear Time- based ADC (T-ADC) is presented. The proposed circuit exhibits high linearity, simple design and low power which make it the best solution for the problems that limit the performance of the MIMO systems. The proposed ADC exhibits a linearity error of 0.56 % with a dynamic range equals to 800 mV and at small power consumption of 2.2 mW. The supply voltage used equals to 1.2 V using industrial 65 nm TSMC CMOS technology. The clock frequency equals to 4 GHz at a maximum input frequency of 2 GHz. © 2021 IEEE.

The increasing demand for energy in urban environments necessitates innovative solutions to harness untapped energy sources and enhance energy efficiency. In the context of Bahrain's efforts toward sustainable smart city development, this research article presents a comprehensive study on power generation using speed breakers as a novel energy-harvesting mechanism to supplement the electricity grid and promote energy efficiency in urban areas. The proposed energy-harvesting speed breaker (EHSB) system using rack-and-pinion mechanism employs a mechanical-to-electrical energy conversion mechanism, transforming the kinetic energy generated by vehicles passing over speed breakers into electrical energy. The study includes the design, construction, and testing of a prototype of the power generation system using speed breakers. The results of the study show that the EHSB system is a viable and sustainable method for generating electricity. The system is capable of generating significant amounts of energy, and it has the potential to contribute to the energy needs of communities located near highways and busy roads. The findings of this research provide valuable insights for Bahrain's policymakers, urban planners, and energy stakeholders, highlighting the potential of innovative energy-harvesting solutions such as the energy-harvesting speed breaker system in promoting energy efficiency and sustainability in urban environments. By incorporating the EHSB system into Bahrain's smart city development strategy, the nation can take a significant step toward a greener, more energy-efficient future.
