Abstract

QoS (Quality of Service) of LTE networks can bring the providers to provide broadband services with high performance to end user.  Furthermore, the expected data rate transfer is up to 300 Mbit/s per user while the range of bandwidth varies from 1.4 MHz to 20 MHz.  The network worked in 1800 MHz bands, 64 QAM modulation technique and used 10 MHz and 15 MHz channel bandwidth.  There is a congestion problem for LTE network with 10 MHz channel bandwidth due to high utilization.  The paper tries to analyze the QoS parameters, named Key Performance Indicators (KPI) for LTE Networks to solve the problem using bandwidth expansion. The KPIs parameter that is measured by drive test is accessibility, retainability, PRB downlink utilization, and user number.  Based on the KPIs measurements results, it is showed that the proposed method to expand the bandwidth from 10 MHz to 15 MHz can avoid congestion problem and impact on improving the performance of LTE network.

Abstract

Perkembangan  teknologi  saat  memungkinkan  akan  konsep  rumah  yang  Hi  – Tech, pada saat ini TV, Home System Audio, mesin cuci, mesin pompa air, dan lain-lain adalah  contoh  beberapa  peralatan elektronik yang  penggunaaannya masih menggunakan tombol  atau  remote  control.  Namun  dengan  konsep  “  Hi-Tech  future  Home  “  dimana semua  peralatan  elektronik  yang  terhubung  dengan  internet  memungkinkan  dapat dikembangkan  dengan  mudah.  Voice  Command  Recognition  System  adalah  salah  satu konsep pengendalian perangkat elektronik dengan menggunakan perintah suara. Dengan konsep tersebut maka semua peralatan elektronik bisa dikendalikan dengan perintah suara dari penggunannya.Pada Jurnal ini akan menjelaskan perancang system voice command recognition yang  digunakan  untuk  aplikasi  peralatan  rumah  tangga  yang  dikendalikan  oleh  suara pengguna.  Perancangannnya  akan  menggunakan  teknologi  Google  Voice  Recognition system, Arduino Uno, Bluetooth dan teknologi transistor untuk mengefisiensi dalam hal biaya perancangannya. Dari  hasil  pengujian  dapat  disimpulkan  bahwa  sistem  ini  memiliki  kelebihan yaitu  mudah  untuk  digunakan,  penerapannya  sederhana  yang  dapat  membantu meningkatkan  kenyamanan  pengguna  (penghuni  rumah).  Akan  tetapi  kekurangan  dari sistem  ini  adalah  sangat  bergantung  kepada  server  google  untuk  dapat  mengartikan perintah suara yang ada, sehingga apabila paket data pengguna system ini terbatas dapat dikhawatirkan system ini tidak dapat digunakan.

Abstract

Electricity is one of the most important human needs. In the presence of electricity it can facilitate human work. But it should be noted that too large and uncontrolled electricity use will be wasteful and get high costs. The problem is that electricity is not monitored accurately, easily and efficiently. This study aims to design an electric current monitoring device with an IoT system. IoT is a concept with the ability to transfer data by network, no need humans to humans or humans to PCs. In this concept, the SCT 013-000 electric current sensor is connected to the load, it will be show electric current value in the LCD, if the electric current which is determined exceeds the capacity, Wemos D1 including Wifi ESP 8266 will be sending a notification to the telegram. The system has been implemented with ironing load for 3.29%, the dispenser load is 0.20% and Magicoms get load for 1.07%. The delay time also has been implemented in the relay for 1.50 second when relay is on and 0.78 second when relay is off. When the notification send to the telegram also have a delay for 6.2 second. So, monitoring of electrical system using internet of things with smart current electric sensors has been done.
