ABSTRACT LED (Light Emiting Diode) currently most of its use is only as an indicator or as lighting a room. In the development of this technology many innovations have been developed, namely LEDs can now be used as high-speed transmission media. Visible Light Communication (VLC) is a communication system that can be used as a process of delivering information using visible light. VLC provides efficiency in wireless communication systems because it offers new bandwidth and has not been used in wireless communications, and has good development potential.

ABSTRACT Technological developments have shown significant improvements, especially for the field of communication. This is evidenced by the many communication media both wireless and wired. In this project, visible light is used as a medium in communication systems, where terminal equipment has been made on VLC technology. The workings of this terminal equipment are when the terminal equipment acts as a receiver, the photodiode module will receive and read the lights on and off from the LED lights to form binary code data. After receiving data in the form of binary code, the web will be converted to the same characters as the sending user. And at the same time the sender can also send information to the recipient, where information sent by the user will be converted to binary form as a command to turn on and off the LED lights according to the bits sent, bit "1" means the light is on and bit "0 "Means the lights are off. From the results of tests conducted in full duplex, the data received is categorized as good because the recipient can properly understand the characters sent by the sender.

A solar module as a collector of sunlight that will be converted into electrical energy, so far only used for various applications of renewable energy technology. This research proposes and demonstrates the application of solar module as receiver of Visible Light Communication System (VLC) as well as collecting energy at the same time. Using a solar module as a receiver causes the receiver does not require an external voltage source. This study tested the acoustic audio signal transmitted through the VLC system to be received by the solar module as a receiver. The results show that the transmitted audio signal has a signal change as a result of the magnitude/amplitude whose value changes with time. The change of voltage level over time causes the LED emission to have different light intensity. Maximum distance of the signal can be transmitted well at a distance of 120 cm at 656 mV voltage with a light intensity of environmental lighting test of 265 Lx. The maximum angle of the signal can be transmitted well at an angle of 20o at a voltage of 190 mV with a light intensity of the test environment light of 265 Lx. The change in voltage values is affected by the LED emission and the light intensity of the test environment light received by the solar module as a receiver. Testing indicates that the audio signal remains well transmitted even though the light energy received by the solar module is in maximum condition.

LTE (Long Term Evolution) is a Broadband Wireless Access (BWA) technology that allows high speed and a wide range of access. LTE is designed to meet the needs for Quality of Service (QoS), i.e. the ability to download up to 300 Mbps and upload up to 75 Mbps. This study investigated the impacts of user mobility on the LTE network for video streaming services. The approach employed in this study included multi-user with Distributed AntennaSystem (DAS) and various variations of user mobility speed. Observations were made on the condition of the user moving from one cell to another so that the handover occurred. The throughput value will increase by 33% and 47% when the userâ€™s distances are respectively 1250 m and 2000 m from eNode B. In addition, the delay value will reduce by 66.32% an 67.58% when the userâ€™s distances are respectively 1250 m and 2000 m from eNode B. Moreover, the PDR value will increase by 48.74% and 55.45% when the userâ€™s distances are respectively 1250 m and 2000 m from eNode B. The use of a distributed antenna system (DAS) model on LTE network has resulted in improved quality of performance when the user streams a video.
