Optimization computer network and bluetooth technology for parallel analysis of data transmission in programming

Technological problems and transmit data can be given a solution using Bluetooth technology. Bluetooth technology is used to transmit data over a distance of about 15 m. This data transmission analysis aims to apply and implement damping on the glass wall using a bluetooth device, in sending data files to replace the function of the data cable. So with this problem, a room that is partitioned using glass walls is designed and built. The hypotheses made: The material barrier factor between the master and slave greatly affects the attenuation of the received signal. In addition to the above factors, attenuation is also influenced by the distance between the master and slave. With two glass skate partitions and the distance between the master and slave will affect the data transfer speed. This study is to determine the attenuation of the double glass wall between the user and the server on the LAN network, using 15 PCs that are placed in a glass-insulated room on the same floor. The Bluetooth used is class 2 with a power of 2.5 m watts with a range of 15 m. The result of this research trial is that attenuation in a room with a glass wall in the room produces power losses, only experienced by the signal between the master and slave, the farther the distance the signal attenuation is, the greater the power losses, which results in more the amount of reduction in transfer rate from master to slave. Communication between computers through the use of USB. Bluetooth is only a simulation signal propagation. One room is used the floor is insulated by glass wall with size of 3m x 3m to measure the master room, 5 x 5m for the slave room. The distance between the server room and the slave room 3m.
