Abstract

This research motivated by the influence kind of substrate to the dimensions of the antenna, gain and impedance, to get the design of antenna with the characteristic consistent with the standards and need of the designer takes the right material. This research to prove the effect of microstrip substrate. The substrate according to the design (features) and desirable for a rectangular microstrip antenna 2,4 GHz. Method used is analisis from the result of the simulation using CST studio suite, the process follow some steps: (1) study literature (2) determining the types antenna (3) determining the specifications of the microstrip antenna (2,4 GHz frequentz of resonance, return loss <-9,54 dB direction) (5) calculating the dimention of the antenna based on the theory (4) simulation using CST studio suite (5) analyzing the result of simulation. From the research can be concluded that there is a value £r of the gain the rectangular microstrip antenna where the larger value £r and the gain will be smaller. There is an influence in the value £r foward the bandwidth to the square antenna microstrip. Which is the more larger the value £r bandwidth make the value smaller. There is an influence in the value £r foward beamwidth to the square antenna mictrostrip, which is the more larger that value of £r, beamwidth will be larger. To design the antenna with high value more than 90° 5dB that is use for the value of £r between 1-3. To design the antenna with the beamwidth that value more than 0,03 GHz that use for the material with value of £r between 1-3.Keywords : kinds of substrate, gain, banwidth, beamwidth, antenna microstrip, CST studio suite

Abstract

The development of Internet use has spurred Wireless Sensor Networks (WSNs) technology so that it becomes a widely researched and applied device. With the need to use high WSNs, the quality of features provided such as high data transfer speeds and the smallest possible disruption is something that should be available. Although some uses of WSNs do not require high speed and have a tolerance for interference, there are very few types of use. Nevertheless, routing protocols are provided to meet the types of data transfer requirements. The protocols available for each type will be analyzed and compared to find out the best performance.Keywords: data transfer, routing protocol, WSN.

Abstract

This research was conducted on the basis of the weakness of the received signal by service users (MS) caused by certain factors such as the geographical structure of a city, many buildings so that the path loss (Path Loss) resulted in data connection failure or call failure. This study serves to determine the comparison of Pathloss values in the Medium-Sized City and Large City Regions in Padang city with a 231-Hata cost propagation model. The measurement method used is the drive test using the Network cell Info LTE application and then analyzed with a model cost 231-Hata, the results of measurements with the RSRP standard research were carried out in the morning and evening for five days. The results showed: In Air Tawar BTS (Large City) by measurement and calculation of the Cost 231 Hata model, compared to the RSRP PT.XL Axiata Padang standard, the signal quality is medium category. While the Lubuk Buaya (Medium-Sized City) BTS is measured, and in the calculation of the Cost 231 Hata model. Compared to the RSRP PT.XL Axiata Padang standard, the signal quality is in Medium category. From the results of measurements and calculations there are differences in pathloss values that are not too significant. This is due to several factors such as building height, road width and geographical structure of the area.Keywords: RSRP, Pathloss, Drive Test, Cost 231 Hata,4G LTE

Abstract

The research was conducted by analyzing the optical fiber attenuation of the DWDM performance in terms of power received on optical fiber communication systems link Padang-Lubuk cone in PT. Telkom Padang. Optical fiber has a very small damping. Therefore optical fibers become the primary choice in telecommunications networks. To improve the transmission quality is better then the use of DWDM technology, DWDM technology is a method to insert a number of channels were transmitted in a single optical fiber. Instruments in this study is the Power Meter and OTDR JDSU MTS-2000 type, the type of cable used G.655 Single Mode type. Link Power Budget method is used to determine the performance of DWDM caused by attenuation based on the value of the received power output receiver. On the link Padang - Lubuk cone highest attenuation occurs in core 1 of 29.742dB with 100.035 km cable lengths, and the core 10 of 31.8 dB with 119.998 km cablelengths. Based on the large fault or attenuation/km core 1 of 0.297 dB/km, the core 10 of 0.265 dB/km and the standard ITU-T was 0.35 dB/km. Value attenuation/km core 1 and core 10 is still in normal conditions and under standard ITU-T 0.35 dB/km. Based on optical fiber attenuation, the results of analysis of the link power budget is the value of Rx is smaller than the value of Rx sensitivity of -27 dBm, it can be said performance DWDM optical fiber communication systems in normal and can be used to operate because the power output can still be accepted by receiver in the device. Keywords:optical fiber cable, optical fiber attenuation, DWDM, link power budget.
