In this article, the rectangular textile antenna is embedded with E-shape Electromagnetic Band Gap (EBG) Structure for reduction of SAR. It is positioned on human phantom model. The E-shape EBG array is positioned between ground and patch of rectangular textile antenna. It is resonant at 2. 4GHz.The substrate material for the rectangular Textile antenna is jeans cloth. The Specific Absorption Rate (SAR), Reflection coefficient and Impedance Bandwidth are obtained with and without EBG structure using HFSS software and also measured.

ABSTRAKPenerapan teknologi Long Term Evolution (LTE) di Indonesia belum optimal dalam pengalokasian spektrum dikarenakan keterbatasan spektrum, untuk mengatasi masalah tersebut 3GPP mengeluarkan teknologi terbaru yaitu LTEAdvanced yang mendukung fitur carrier aggregation (CA) yang memberikan throughput yang lebih tinggi dengan penggunaan spektrum yang lebih efisien. Pada penelitian ini dilakukan perencanaan jaringan LTE-Advanced menggunakan metode inter-band CA dengan menggabungkan dua band frequency yang berbeda yaitu bandwith 5 MHz di band 5 (850 MHz) dan bandwidth 10 MHz di band 3 (1800 MHz). Untuk mendapatkan performansi yang maksimal perencanaan jaringan LTE dan LTE-A dikombinasikan dengan penggunaan skema Physical Cell Identity (PCI) dan Soft Frequency Reuse (SFR). Penggunaan PCI meningkatkan SINR sebesar 1 dB dan throughput meningkat sebesar 200 Kbps, sedangkan penggunaan skema SFR meningkatkan SINR sebesar 9 dB dan throughput meningkat sebesar 13 Mbps.Kata kunci: LTE-Advanced, PCI, SFR, Carrier Aggregation. ABSTRACTThe implementation of Long Term Evolution (LTE) technology in Indonesia has not been optimal due to spectrum limitations. To overcome the problem, 3GPP issued the latest technology, i.e. LTE-Advanced, to support the carrier aggregation (CA) feature that provides higher throughput with more efficient spectrum usage. In this study, LTE-Advanced network planning was performed using the inter-band CA method by combining two different band frequencies, namely 5 MHz bandwidth on Band 5 (850 MHz) and 10 MHz bandwidth on Band 3 (1800 MHz). In addition, to generate maximum performance, the LTE and LTEA networks planning was combined with the use of Physical Cell Identity (PCI) and Soft Frequency Reuse (SFR) schemes. The use of the PCI managed to increase SINR by 1 dB and throughput by 200 Kbps, while the use of SFR scheme managed to increase SINR by 9 dB and throughput by 13 Mbps.Keywords: LTE-Advanced, PCI, SFR, Carrier Aggregation.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.
