We present a simple design and realization of a low-cost FMCW radar. The modular design, separated the system into baseband and RF system, makes the working frequency changeable and the bandwidth programmable. The baseband is built from low-cost microcontrollers, whereas the RF system consisting of basic components of an SFCW system. We present a realization of a S-Band UWB radar with a programmable...
The energy consumption in residential has been increased over the past years. Many researches to conserve electrical consumption have been presented. Providing residents with information on their energy consumption has become a feasible option to promote energy saving in residential sector. In this Paper, the electrical energy monitoring systems are designed based on a non-intrusive sensors, Bluetooth...
The proposed NMS, called ITB NMS, is a web-based centralized management system used to manage and monitor the current condition of the entire existing network infrastructure clearly and concisely. ITB NMS is used to monitor a device or devices connected to the network-based LAN, WAN or Internet. ITB NMS is able to monitor the condition of a device or monitor the activities being performed by a device...
In this paper some telecommunication regulatory incentives are described. Network sharing is one of among other incentives that has been proposed. However this incentive creates some disturbance to the telecommunication level of playing field. This paper examines the solution of network sharing and co-investment by multiple operators and potentially other sources, including the government itself,...
This effort aims to design and fabricate a triple frequency rectangular patch antenna, by attaching a single stub element of a varying length (rectangular-shaped), to the top left corner of radiating edge of the patch, to act as a tuning network. The patch and the stub are excited through a 50 Ohms insert-fed line, connected to a midpoint of the patch. The whole structure is embedded on a single FR4_epoxy...
In this paper, the process of generating a signal frequency modulated continuous wave (FMCW) using direct digital synthesizer (DDS) will be presented starting from the design process simulation using the software on the computer until the realization and measurement of the generation of such signals on a module DDS, the kits from Analog Devices. Generation conducted a baseband signal with a bandwidth...
This paper presents an investigation of the effect of various changes in each dimension components that build Split-ring resonator (SRR)-based bandpass filter (BPF) to its characteristic. The most suitable dimension is used to develop three elements SRR-based BPF design that intended to operate at around center frequency 2.4 GHz for wireless application and deployed and fabricated on Rogers RT/duroid...
Filter in telecommunication is a device which has function like a frequency band selector. it plays an significant role especially to select the frequency band that is wanted to be passed through. At this advanced technology era where every device is getting compact in design and size, the filter model also has been challenged in order to meet and fit the recent situation. The microstrip filter is...
The CS (Compressive Sampling/Compressed Sensing) is an emerging technique in signal processing, which enables the development of better methods and devices. This talk presents a brief review on the progress of CS after a decade of its developments. First, the principle of the CS and the difference with classical sampling is explained. Then, early developments on CS-methods and related applications...
Long Term Evolution (LTE) is one of the latest generations of the mobile cellular technology, while High Altitude Platform Station (HAPS) is envisaged to be the novel wireless infrastructure. Compared with existing wireless system such as terrestrial and satellite system, HAPS have been proposed to be a complementary technology of mobile cellular system. HAPS channel characteristic can be approached...
Low noise amplifier (LNA) presented in this paper is intended for L-band communication application, where the topology of LNA consists of two-identical stage cascade LNA. Matching network used in this paper optimizes noise figure. The cascade LNA design achieves high 35.56dB gain and low noise figure of 0.628 dB with only 38.52 mW power consumption. Broadband vector signal analysis demonstrates high...
Nowadays the widespread use of variety of smart phones and tablets with wide range of multimedia application support is driving more data service users towards full mobility causing a rapid increase in demand for mobile data rates. These new devices and multimedia applications require high data rates and reduced latency to provide better Quality of Service (QoS). To address these requirements the...
Obtaining a high range resolution is an important issue in a detection and ranging system, such as in a radar (Radio Detection and Ranging) or sodar (Sonic Detection and Ranging). A frequency-domain system, such as the SFCW (Stepped-Frequency Continuous-Wave), capable to offer a high range-resolution due to its capability of wide-band scanning, as showed in the SFCW-GPR system. Despite its simplicity,...
The use of a bigger and more reliable transmission network such as Dense Wavelength Division Multiplexing (DWDM) is proven to support telecommunication providers in implementing broadband technology. Analyzing the DWDM implementation in PT. XYZ, this study focuses on the transmission network employing the techno-economic method. The use of this method involves two purposes. First, it aims at establishing...
Video applications are essential nowadays. Even though almost everyone has access to it right now, the means and ability to access it is not uniform. Some of the important aspects to consider are the bandwidth available on the user and the video codec compatibility. Therefore, we need to find a video codec which can be played on most currently available devices and apply lossy compression to get smaller...
The growth of telecommunication devices has driven the development of technology of Mobile IPv6 (MIPv6), which supports the concept of seamless communication. One of MIPv6 extention is Hierarchical Mobile IPv6 (HMIPv6) were developed to reduce the delay at the time of vertical handover process by utilizing Mobility Anchor Point (MAP) whose enhancement to shorten the process of configuring the IP address...
In this study, the implementation of monitoring system is made, aimed for home surveillance. The sensor of the system is camera. The camera will capture image of the room and will evaluate whether an intruder is detected or not, by subtracting the image with the background frame. When the intruder is detected, the system will automatically activate the alarm to alert the home occupant. In the same...
